Knock out plumbing is fantastic from the start (driving to your house) to the finish.Their technicians are the best... very knowledgeable and polite. They aim to please!
keith rozelle
Dan originally came out and gave me a quote to Install a high-pressure Mister system. Dan was on time and punctual and very professional. Both of his guys Thomas and Jordan put in a super long day and did the most amazing job. They were very concerned about me being happy with the work, I own an air-conditioning company with lots of employees, and the way they did business was exactly how we do business. I was pleasantly surprised. I would recommend these guys to anybody

Angela Janke Longenecker
In discovering water seepage in our kitchen, the only plumber I knew to reach out to, through a networking group I was in, was Knockout Plumbing. The owner of the company, Dan Harper, was at our house promptly the morning after I called. With not knowing how much, or how long, water had been seeping, Dan first saw we have to dry out the area and find the leak. He was responsive to all our questions with this being the first time my husband and I have experienced this, Dan explained everything he was doing and why. He has answered all of our millions of questions, been at our house when he said he would and has a fantastic team of plumbers. I love that Knockout is a family owned, small business. I much prefer to support small business and highly recommend Knockout and Dan Harper if you want your work done right, done promptly and have someone who answers their phone.
Joyce Petrowski
Technician was punctual, respectful, helpful and very professional. Will definitely be using them again and referring them to friends and family
NikkiH
We ran into an emergent issues with my grandmothers water heater. It had burst and needed to be replaced asap. Knockout Plumbing was so quick to assess and replace her water heater and even checked her water pressure in her shower, at her request, and adjusted for her. They took the time and effort to make sure she was taken care of. I highly recommend their company to anyone in need of plumbing services.
Andrew Rubenstein
Exceptional service. Highly recommend their team. Could not have been more responsible, respectful and knowledgeable. An absolute pleasure .
cindyscott mathe
Knockout Plumbing has been amazing, the serviceman Matt was kind through and completed the tasks asked of him.
Tamara Rivas
Emergency service on a major holiday! Dan was nothing less of exceptional! He got off a plane receiving my call and came right over. And it was the 4th of July…it wasn’t even an hour before he arrived-he literally saved our holiday as well as my business in proceeding for the day. I would 1,000% recommend this business to anyone. I am a forever customer and his work was far above satisfactory! Thank you, Knockout Plumbing!⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️
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
He was very good at what he fixed. He was here on time. He is very friendly.
Jon Simmons
This is the 2nd time since moving to AZ that we have needed a plumber. I would never use anyone but Knockout.Dan is the man. He is always on time, professional, and does amazing work. All at a reasonable price. Use these guys. You won't have to worry if the work was done right. Thank you so much Dan and Knockout Plumbing
Anita Jordan
Matt was here and install two new hose bibs for me. Everything works and nothing is leaking anymore which is wonderful. Matt was very personable and did a great job! He even answered questions I had about the hot water tank and advised me on the settings. Thanks Matt!
Christine Salley
Was having flooring done and found a leak from the fridge. Called and had plumber out next day, very helpful and knowledgeable. Fixed my problem and made me very happy. Second experience with Knockout, will definately used again.
Jose Acosta
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!
Erica Faye Schmidt
Had a water emergency over the weekend KNOCKOUT PLUMBING was at my residence within a hour and had it repaired within minutes the job was professional in the repair was very well done very impressed with this business-defintely will use again and recommend
Steve Malone
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.
Christin Barros
Knockout Plumbing did an excellent job replacing my sink and installing an RO system. The crew was on-time, knowledgeable and professional. My family and I can now drink safe water while being environmentally friendly! Thanks Knockout for your outstanding customer service.

They are helpful and on time. Gave us some good advice about our old home.
Jack Hamblet
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.
Karen Nielsen

Justin R.
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.
Am Norgren
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!

Hayley Kirk
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.
Mark Taylor

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!
R R
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!
S Sk
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

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!!!

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.

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!
Jamie
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
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!
