The two most common trenchless sewer repair options are pipe lining (also known as cured-in-place pipe lining or CIPP) and pipe bursting:

  • Pipe Lining (CIPP): This method involves inserting a flexible, resin-coated liner into the existing damaged pipe. The liner is inflated and cured in place using heat or UV light, creating a new, structurally sound inner pipe within the old one. It’s suitable for repairing pipes with cracks, corrosion, and minor deformities without excavation.
  • Pipe Bursting: In this technique, a new pipe is pulled through the old damaged pipe, breaking it apart while simultaneously replacing it with the new pipe. The bursting head breaks up the old pipe, pushing the fragments into the surrounding soil. This method is used when the old pipe is severely damaged and needs replacement.

Both methods minimize the need for extensive digging, reducing disruption, costs, and environmental impact associated with traditional trench digging methods when repairing or replacing sewer lines.

Fixing tree roots in a sewer line requires a strategic approach to prevent further damage and restore proper flow. Here’s a general process:

  • Camera Inspection: Begin with a sewer camera inspection to locate the root intrusion and assess the extent of the damage.
  • Root Removal: Use mechanical tools like augers or cutting blades to remove the roots from the pipe. Hydro jetting can be effective in breaking up and flushing away smaller roots.
  • Chemical Treatment: Apply root-killing foams or chemicals to inhibit root regrowth. These treatments can be effective if used cautiously and following manufacturer guidelines.
  • Pipe Lining: Consider using pipe lining techniques to rehabilitate the damaged pipe. This involves placing a resin-coated liner inside the existing pipe, creating a new, durable inner surface that resists root intrusion.
  • Regular Maintenance: Regularly schedule professional inspections and maintenance to prevent future root intrusion. Trim trees and plants near the sewer lines.
  • Professional Help: Tree root removal from sewer lines is best handled by experienced plumbers or rooter services to ensure proper techniques are used and to prevent further damage.

Mitigating root intrusion involves a combination of root removal, preventive measures, and repairs to ensure the sewer line’s functionality and longevity.

The effectiveness of a water filtration method depends on the contaminants present and the desired water quality. There isn’t a single method that’s universally best, but several options are highly effective for specific purposes:

  • Activated Carbon Filtration: Effective at removing chlorine, volatile organic compounds (VOCs), and some taste and odor issues. Can be enhanced with additional filtration media.
  • Reverse Osmosis (RO): Highly effective at removing a wide range of contaminants, including minerals, heavy metals, bacteria, and viruses. Produces very pure water.
  • UV Water Purification: Destroys bacteria, viruses, and pathogens using ultraviolet light. Often used in combination with other methods for comprehensive treatment.
  • Ion Exchange: Effective at removing minerals like calcium and magnesium that cause water hardness.
  • Distillation: Heats water to create steam and then condenses it to produce purified water. Effective at removing many contaminants.

Choosing the right method depends on water quality, specific contaminants, and your needs. Combination systems can provide comprehensive filtration. Consulting water treatment experts and conducting water quality tests can help determine the most effective method for your situation.

The average life expectancy of a water heater varies depending on factors such as the type of water heater, usage, maintenance, and water quality. Here’s a general guideline:

  • Traditional Tank Water Heaters: On average, a well-maintained tank water heater can last around 8 to 12 years. Regular flushing to remove sediment and checking the anode rod can extend its lifespan.
  • Tankless Water Heaters: Tankless units generally have a longer lifespan, lasting around 15 to 20 years or more with proper maintenance. Since they don’t store water, there’s less risk of tank corrosion.
  • Water Quality: Hard water with high mineral content can lead to faster sediment buildup and reduce a water heater’s lifespan.
  • Usage: Frequent or heavy usage can wear out components faster, shortening the heater’s lifespan.

Regular maintenance, such as flushing, checking components, and addressing issues promptly, can help maximize the longevity of your water heater. It’s recommended to consult the manufacturer’s guidelines and consider professional inspections for a more accurate assessment of your specific water heater’s expected lifespan.

Drinking water from a water softener system depends on the type of water softener and its design. Conventional ion-exchange water softeners replace calcium and magnesium ions with sodium ions. While softened water is safe for most people to drink, it might contain higher sodium levels, which can be a concern for individuals on sodium-restricted diets, those with hypertension, or heart conditions.

To ensure safe drinking water:

  • Separate Tap: Install a separate tap for drinking water that bypasses the water softener. This way, you can have access to both softened and unsoftened water.
  • Potassium Chloride: Opt for potassium chloride as a regenerating agent instead of sodium chloride. This reduces sodium levels in the softened water.
  • Reverse Osmosis: Use a reverse osmosis system for drinking water to remove not only excess sodium but also other contaminants.

Regular maintenance, monitoring sodium levels, and considering the specific needs of household members will help you make an informed decision about drinking water from a water softener system.

    Daisy Weingarten
    Friday evening, after work, I came home and noticed a pretty serious water main leak in our front yard. I called around to a few places with no one really available, I saw Knockout’s reviews and decided to try them. I got in contact with Dianna, she stopped what she was doing so she could take my information and find someone asap, let me know she is going to get in contact with the closest person to come out right away. Sure enough, not even an hour later, Dan shows up. By this point the sun has gone down but Dan doesn’t care, he’s totally on it. He is probably thee most knowledgeable person I have spoken too in regards to plumbing, he broke it all down and explained to us whats going on, what our options are. He also explained that they only use quality materials with 25 year warranties, and the quote I got? SUPER affordable. Best part? He could come the NEXT MORNING!! Dan also took the time to reexplain everything as much as I needed and was totally patient with us. He helped us shut off the water as our shut off wasn’t doing any good. He really cared about making sure we weren’t going our weekend without water. Dan and his team are so personable, knowledgeable and prompt. He was right on time the next morning, ready to go. Joey was also there helping get the job done, he also took the time to explain things to me when I had questions. They just earned my support for as long as their in business (which is local and family owned btw!), seriously, don't waste your time with anyone else. Even though I only spoke to 3 and met 2 of them, I just know the whole team are rockstars!! Thank you Knockout for saving us!! You guys are the best!
    Daisy Savage

    This is my second experience with Knockout and even with a different plumber they did not miss a beat. I had the pleasure of working with Matt this time for a water heater issue. He texted me and asked if he could come early which was great for me and I really like the excellent communication from this company throughout the entire process. My heater was 10 years old so unfortunately had to be replaced. Matt explained the differences between a tank and tankless system including providing me all in pricing which I absolutely love in this era of extra fees for absolutely everything. Amazing Matt had already replaced my heater within about an hour of my initial appointment time!What more can you ask for? Fair, knowledgeable, communicative, great customer service, fast, clean, and friendly!! Thanks again to my go to plumbing company!

    Justin was FANTASTIC!! Our water softener failed causing all of our pipes, valves, faucets and water heater to be clogged. Justin worked 12 hours on the first day ensuring we could use our toilet and get water in our kitchen. He was back early the next day to install a new softener, tankless water heater, faucets, shutoff valves and check all our appliances for any damage. Knockout also provided financing with no payments and no interest for 12 months. We are very grateful to Knockout Plumbing for their professional and caring service.

    Mike was great, he came out and really saved the day for us. He quoted and completed the job same day. Unclogged the sink and fixed a broken pipe in our historic home. Everything is clean and working well.

    It is hard to find good service these days, but my experience with Knockout was excellent. Dan is who came to rescue us and we are really impressed with him and this company. He is definitely a master of his craft, very honest and up front, and just a pleasure to deal with. I don’t normally get around to doing reviews and usually forget but I had to come on here and make sure I did due to our experience with them.We sprung a leak from our main 1” feed line coming up through the wall in the garage that crosses over the attic to our laundry room at the water softener loop, and made a pretty good mess. We were able to catch it after coming home from dinner around 12am before it became a disaster and ruined everything like our last leak we had. I shut off the supply to the house and the wife and I started looking at plumbing companies and reviews to put in an emergency call. We called 4, 24hr companies and Dan was the only one to call back at all, and within minutes.He was able to come out promptly and arrived at 5:30am to assess the situation, and perform the need repairs quickly. He would have been there at 2am but needed to track down 50’-60’ of 1” pex pipe. He gave me a very reasonable quote and did a fantastic job on the repairs. It was done within a few hours and was a pretty extensive repair. Had to run 50’ of pex through the attic to the laundry room. He cleaned up the areas really well when he was done and was on to the next rescue.Overall we are completely satisfied and will be using Dan and Knockout Plumbing for all of our future needs for sure. Very pleased.A+++ service.

    On Monday night, I realized I had a problem. The only toilet in my house was bubbling when we ran the shower. That’s when I found Knockout Plumbing. They were responsive and quick to address the sewer line issue. Thomas went above and beyond to resolve the problem, and the rest of his team was professional and efficient. Highly recommend!

    Knockout Plumbing is a top notch company that you can truly rely on. They respond quickly, have great employees that work hard, respond timely, & well managed. They care about their customers and want to get to the root of the problem and use quality parts and finishes. They shoot you straight, fit you into the schedule in a very timely manner, and if you have a true emergency they will get there right away. All their plumbers are knowledgeable and just genuinely nice people. I have called them out for nearly every issue or install one could need a plumber for (I run a property management company) and they always take great care of my clients and their homes. Can’t recommend them enough.
    Robin Gates
    Thomas with Knockout Plumbing was very helpful in determining the root of our leak and was quick to repair it. I highly recommend Knockout Plumbing, and their entire team! The owner Dan takes great pride in their clients with great customer service. I will definitely be using them in the future and will recommend them to my friends and family.
    Bryan Seppala
    We have used Knockout Plumbing twice now and couldn’t be more impressed with their professionalism, response times, quality of work, and their care of their customers. We highly recommend Knockout Plumbing for all your plumbing needs in the East/Southeast Valley. Special shout out to our tech Thomas; great customer service and communication! 5 stars all the way.
    Brian Stanley
    I though I might have a slab leak or some outdoor leak, came by the next day at appointed time, looked it over and determined it was the irrigation lines, gave me a little education and did not charge me. Nice guys and very competent. Would recommend to anyone.

    Great Company

    Tech Cody arrived withing the two hour window. He was professional and knowledgeable. He was able to attach the pvc to the garbage disposal and stopped all leaks very expeditiously.Would highly recommend this company.
    Kimberly Beck
    So helpful and knowledgeable! On time and great communication via text to let you know they’re coming. I like they send a picture of your tech so you know who to expect at your door. Fast and polite service. Thanks again!

    Quick response when I was in a bind. Professional staff and workmanship. No one ever likes to pay for repairs but in the end, money well spent.
    amber thomas
    These guys are extremely professional, Joey replaced our shower cartridge and valve in less than 90 minutes. They also had the lowest estimate of all the companies we contacted. We couldn't be more satisfied with the entire process, you can tell Dan (owner) runs a tight ship. We definitely found our go to company for anything plumbing related.
    Victoria DeGarmo
    We had a leak in our irrigation line (that we don’t use) and the source was coming off our hose line in our backyard. I called Tuesday afternoon and Cody was here by 8:30a the following morning. He was able to cap off the irrigation line and installed a new hose bib and it turned out even better than I thought because he capped off the line all the way to the ground getting rid of a lot of the ugly pipping. Super professional and they were upfront with pricing and it was reasonably priced as well. Will definitely be calling them again for future plumbing needs! 10/10!

    I had a clog in my kitchen sink Josh from Knockout came out to fix it he was very professional, nice and friendly he did a great job. Price was very reasonable. I will definitely use him again and I already have told two people about him. Great young man. Thanks, Josh, for your help.
    Barb Hoffman
    The whole crew was polite, on time, efficient and friendly. We had our previous solar water heater and gas water heater removed and replaced with a tankless system. After adjustments, the system works very well! Hot water comes quickly and endlessly. We also had a whole-house water softener system installed. They cleaned up well and checked up to make sure we were satisfied. We recommend Knockout to call for all your plumbing needs!
    Tammy Whitten
    They sent Cody, and he was such a professional. He was polite, and explained everything in detail, even gave us a heads up on future fixes we need to keep an eye on. He’s Honest and hardworking, we got excited when he was assigned as our plumber again. We’ve had nothing but amazing experiences with this company and their worker, Cody.
    Heide Cunningham
    A big shout out to Josh from Knockout plumbing. Highly recommend for all your plumbing needs. Josh went above and beyond bringing new toilets , installing and disposing of the old ones. Very knowledgeable, great guy. He was on time. Did an awesome job!! We love our new toilets. Thank you Josh!!!! Oh and he got everything done in one day.
    Savannah Harper
    Knockout Plumbing did an amazing job. Very punctual and reasonably priced. Will definitely be using these guys again in the future.

    Clean, on time, personable, and professional. A bit expensive, but, I guess all plumbers are.
    Livia Flood
    We had Knockout Plumbing install a gas line to the kitchen so we can install a gas stove. Terrance was great to work with and the price is so very reasonable. Highly recommend!
    Shelah Rycraft
    We had a leak that totally destroyed our flooring knockout Plumbing was contacted within the hour they had restoration out here and they were right behind them. Getting to the source of the problem shutting the water off the following day a total re-pipe of our home . Dan was professional and very understanding and empathetic to our current situation. Since then he has been here multiple times fixing toilets replacing and working on our irrigation to our fruit trees. Very much joy to have around. His personality and knowledge is very reassuring. This company is the only company that will ever perform any work in my home regarding water. As well as I will look to him for referrals of companies that I might need to accomplish other areas that might need repair. Thank you for all your hard work Sheila rycraft
    Matthew Giltner
    I actually use to work for dan and his family. Dan is one of the best bosses I’ve ever had. He is really genuine and hard working. The only reason why I left the company is because I moved back to Chicago. Working for dan or getting service from knockout plumbing. He really knows how to make you feel like family!!!

    Excellent customer service by David Layne. He came out on a Saturday at 5:00PM to repair our water heater. Not only did he do great work but he was polite, courteous, and very caring. We appreciated his positive attitude and follow up service.
    Christin Breeding
    We hired Knockout Plumbing to install two new toilets in our home. They were responsive, timley and quick to install. They cleaned up after the job, were knowledgable and their prices are extremly competitive. Thank you Knockout Plumbing for your excellent work. We look forward to working with you for our future plumbing needs.
    Scott Baglien
    Great service! Communication is too notch and they are very knowledgeable! Thanks Joey
    I find Knockout Plumbing to be responsive, understanding, professional, and willing to explain clearly what the issue is. Also, explained what I could do better without being judgemental. Great company. Will continue to use them.
    Zoa Loper
    David arrived on time, was very pleasant and professional. The job was completed timely and everything was tidied up once complete. Price seemed fair. I would use them again.
    Sumanth Varma
    The knockout team installed the gas lines, pool heater and gas fireplace. They did a professional job and were good to work. Cleaned up after they were done. I also recommended them to do my neighbors pool.
    marty breeding
    Dan and his crew are top notch!! I would highly recommend him. His passion and quality is like no other.
    Jared Elmendorf
    Had a slow water leak at my main riser outside. David arrived on time, was very friendly and professional, and assessed the situation quickly. Provided me a reasonable quote right away and "knocked out" the work within an hour. Very satisfied customer here!
    David and Terrance installed a new faucet for us today, and it was a great experience. They were polite and cleaned up, and our new faucet is perfect! Scheduling was easy, too. Would highly recommend Knock Out Plumbing!
    Jeffrey Miller
    The only plumbing company I deal with anymore. Most recently, we had our very old sewage line / clean-out give up and cause sewage to back up into our bathrooms. Knockout Plumbing came out quickly to evaluate the issue and made the repair work happen quickly. The work was heavy and required the lines to be dug out and completely replaced. David and Terrance worked hard to get everything done quickly and provide great communication along the way. We even had them install a new tankless heating system to boot.Thanks again!
    Jennie R
    Dan and Diana from Knockout Plumbing are AMAZING! Dan had to come out to fix a blockage that was caused by the builder leaving a piece of broken pipe in the main sewage line in my house. They are professional, personable and very knowledgeable. Definitely goes above and beyond even called me over the holiday weekend when he was out of town to come and fix my issue when water started backing up in the showers and sinks. They are a family and community oriented business and they have earned my business for life! Sorry Dan and Diana you are stuck with me! LOL If you need reliable, professional and reasonable plumber you need to call Knockout Plumbing, they are indeed a Knockout! 🙂
    Kaitlyn Trow
    I’ve been told by SO MANY plumbing companies that fixing my toilet will cost a FORTUNE something I can’t afford to fix with the prices they were telling me. I spent MONTHS trying to get this problem fixed and I eventually lost all hope and a lot of money just for my toilet to still not work.However, I decided to give it a try one last time. I found Knockout Plumbing online and gave them a call. Joey Leduc came by that same day! To come check out the toilet that has been causing me so much stress and to my complete shock Joey fixed my toilet with the snap of his fingers! He made it look sooo EASY! And he didn’t charge me an arm or leg. Thank you so so much Joey. I will forever use Knockout Plumbing! I wish I could rate this 100 stars!
    Tamira Burns
    Knockout Plumbing replaced the kitchen sink, pipes and service lines in my 100 year old home. The cabinet opening had to be recut and squared. Dan was patient and efficient. The job was done perfectly and he hauled away the old sink, pipes and service lines and even the boxes from the new sink and faucet. The price was fair and workmanship top notch! Highly recommended.
    Jeff Hutchinson
    We had an outside faucet that had baked in the sun for years. It had seized up, and we couldn't even remove the hose. Dan came out, gave us a resonable price and was willing to fix the issue right away. It was 106 out there and he had to cut pipe, rethread, attach a new extension and faucet (sorry, layman's terms). Anyway, it's better than the original, totally happy with his work.
    Aphrodite Gkigki
    Awesome service! Among the very few companies that service areas out in the desert and on top of it, they do an amazing super professional job. Called for a clogged drain and they showed up on time, were professional and friendly. Dan explained what was wrong and that my drain required more work and quoted me a very reasonable price. Extremely happy and satisfied with the service and professionalism. Will definitely use again and highly recommend to everyone!
    Zariah Shambre
    Joey Was Amazing!! We had a urgent plumbing need at 4pm, he was there by 5!! Done and done!! Thanks you Joey for being awesome at what you do!!
    Bill Berry
    Phenomenal service, quality and professionalism! Dan arrived on time, thoroughly examined the necessary repairs, clearly explained what was needed and provided top notch workmanship! Definitely use this company...integrity at it's finest! Will 100% refer to others.
    Chris Petersen
    I had a great experience with Knockout Plumbing. David arrived right on time, fixed my issue quickly and charged a fair price for the work. I have already recommended Knockout Plumbing to friends and would definitely use them for future repairs.
    Heather Saline
    Knockout Plumbing did a wonderful job replacing our old water heater with a new tankless water heater. They were very professional and had GREAT customer service. I highly recommend them for anyone who needs any plumbing needs. Thanks again!
    jacob laberteaux
    Great service for a great price. They were able to unclog my drain in a quick and clean manner. Highly recommend this company for any plumbing work.
    Johanna Richards
    Knockout was amazing! Their quote was slightly higher than a competitor but I listened to my instinct and was SO GLAD I hired them. Unexpected problems came up and we went from just planning a patch to installing an entire new sewer system and navigating issues with a lot of people involved. Dan was very helpful patiently explaining everything several times and giving me options. He even helped advocate for me with my city. Dan and Joey and the crew went above and beyond multiple times and didn’t charge for the extra things that came up along the way or the extra time it took to get it taken care of. We were under a tight deadline and they made it happen. Would highly recommend to any friends with sewer related issues.
    Martin Burgos
    Came out the same day and fixed my issues with no bs sales tactics! Thank you!
    Ron Sears
    They provided some clean up services at a Multifamily property we own. They were very reasonable on the price, did a great job and took care of it quickly. I’ve been very pleased with their service.

    Last summer (2020) I was faced with one of the biggest challenges of my life. A close relative who lived for a decade in the townhouse I owned -- a three-bedroom, 2.5-bath house with laundry room, backyard, and two-car garage on a corner property -- in Gilbert had to have multiple bypass surgery and had to move out of state for recovery and beyond. Unfortunately, I discovered that the home was in serious disrepair and I had to embark on an almost eight-month cleanup, repair and remodeling project. Since I live in New York City, am a senior, and we were (still are) in the midst of a plague that prohibited travel, completing the project with any chance of success in preparing the property for a profitable sale seemed almost impossible. To make a very long story short, my experience with suppliers and service providers was mixed, from con artists who tried to rip me off and those who succeeded to the incompetent, and from the simply adequate to the extraordinary -- which is where Knockout Plumbing comes in. Thankfully, the Knockout Plumbing team, headed by David "Dan" Harper, were there from the start of the repair process, which began with fixing some leaks. Turns out that Knockout Plumbing repiped the entire home (eliminating copper), put in a new water heater, installed new toilets, bathtub/shower combo and findings, and worked with a separate supplier who created a walk-in shower in the master suite. Dan received and installed new vanities/sinks I sent from Wayfair, and he purchased and installed a kitchen sink, dishwasher, and garbage disposal. In addition, Dan and his crew went over and above the stellar plumbing work, often just checking in on other work being done around the house, keeping me posted on non-plumbing progress. He referred other knowledgeable, dedicated specialists to me and always took the extra step; and when we encountered an unexpected problem, he always found a solution. I could go on forever, but simply put, here's my Report Card: Quality of work: A+; Work ethic A+; Customer service/customer care A+; Trustworthiness: A+; Pricing: A+; Attention to detail: A+; and Responsiveness/Availability: A+. P.S. The house sold first day on the market, well above what was expected at the beginning of the process. I would not have survived this, let alone have achieved such profitable results, without Knockout Plumbing!
    Jason Meraz
    Dan was awesome I called him, as I accidentally broke a pipe , he was at my house in less then 15 minutes he went above and beyond to fix a pipe that is no longer up to code I definitely recommend him ! I will be using him as my local plumber from now on. Very pleased with the professionalism.
    Laurel McGee
    Knockout Plumbing came to my home based on my inaccurate report of what I thought was a problem. It turned out to be a much simpler situation. I am very grateful for the experience of the tech who fixed it. Fast, courteous, experienced and thoughtful. I highly recommend this company for big and small plumbing needs.
    Cathy Vaivao
    Great service, called for leak same day showed up and found leak needed restoration company sent over a company recommended by them all done with one phone call to Knockout plumbing!! Thank you for the great service! I do property management as well and had a property with an alley that people tend to dump trash Dan and Joey w/knockout volunteered to bring their trailer and pick up all the trash to help out! Not only do they repair plumbing issues but also help out our community to look better!! Thanks again Knockout!!!
    Ellen Hecker
    Dan was responsive to all of my questions as well as offering honest suggestions without any pressure for me to follow through with them. He uses technology to keep us informed of his status which was greatly appreciated.
