FAQs on Backflow Prevention

The prevention of backflow is achieved through the installation and proper maintenance of backflow preventers. These specialized devices are strategically placed in plumbing systems to ensure that water flows in one direction, preventing the reverse flow of contaminants into the clean water supply. 

Various types of backflow preventers, such as Pressure Vacuum Breakers (PVB), Reduced Pressure Zone Devices (RPZ), and Double-Check Valve Assemblies (DCVA), serve distinct applications based on the degree of potential hazard. Regular inspection, testing, and maintenance by certified professionals are crucial to guarantee the efficacy of backflow prevention systems. 

Adherence to plumbing codes and regulations, which often mandate the installation of backflow preventers in specific settings, is fundamental to safeguarding public health and maintaining the integrity of the water supply.

A backflow preventer plays a crucial role in maintaining the safety and integrity of a plumbing system by preventing the undesirable reversal of water flow. Its primary purpose is to safeguard potable water supplies from contamination, ensuring that water flows in one direction only — from the public water supply into the consumer’s plumbing system.

Here’s a breakdown of the key purposes and functions of a backflow preventer:

  • Contamination Prevention:

Cross-Connection Control: A backflow preventer is installed at strategic points in a plumbing system to guard against cross-contamination. Cross-contamination occurs when non-potable water (water that is not safe for human consumption) flows backward and mixes with the clean, potable water supply. This can happen in situations where there is a sudden drop in water pressure, creating a vacuum that draws contaminants into the water supply.

  • Protection from Backflow Incidents:

Backsiphonage Prevention: Backsiphonage happens when there is a negative pressure in the water supply system, pulling water from the consumer’s plumbing back into the public water system. This can occur during events such as a water main break, firefighting, or other situations that cause a significant drop in water pressure. A backflow preventer acts as a barrier, preventing this backward flow and protecting the public water supply from potential pollutants.

Backflow due to High-Pressure Situations: In certain circumstances, such as high-pressure events in the consumer’s plumbing system, water can flow in the reverse direction. A backflow preventer ensures that this high-pressure water doesn’t contaminate the public water supply.

  • Compliance with Regulations:

Mandatory Installation: Many jurisdictions and water authorities mandate the installation of backflow preventers to comply with plumbing codes and regulations. This is a critical measure to safeguard public health and ensure that water supplied to homes, businesses, and public facilities remains free from contaminants.

  • Versatility in Applications:

Diverse Settings: Backflow preventers are versatile and can be installed in various settings, including residential, commercial, and industrial properties. They are commonly found in irrigation systems, fire sprinkler systems, boilers, and other areas where there is a potential for cross-connection.

  • Types of Backflow Preventers:

Variety of Designs: There are different types of backflow preventers, each designed for specific applications. These include pressure vacuum breakers (PVB), reduced pressure zone devices (RPZ), double-check valves, and atmospheric vacuum breakers, among others. The selection of the appropriate type depends on factors such as the degree of hazard, system design, and local plumbing codes.

A backflow preventer serves as a critical component in ensuring the safety and quality of our drinking water. By preventing the backward flow of water and potential contaminants, it plays a vital role in protecting public health and maintaining the integrity of plumbing systems across various settings.

Your house is equipped with a backflow preventer for a crucial reason: to safeguard the purity of your drinking water and prevent any contamination that could compromise your health and the integrity of the public water supply.

Here’s a detailed explanation of why your house has a backflow preventer:

  • Protecting Potable Water:

The primary purpose of a backflow preventer in a residential setting is to protect the potable water supply. Potable water is water that is safe for human consumption. Without a backflow preventer, there is a risk of contaminants entering your home’s plumbing system and subsequently flowing back into the public water supply.

  • Preventing Cross-Contamination:

Cross-contamination occurs when there is a reversal of water flow, allowing non-potable water (water not suitable for drinking) to mix with the clean, drinking water supply. This can happen due to a drop in water pressure, and the backflow preventer acts as a barrier to ensure that water only flows in one direction — into your home.

  • Compliance with Plumbing Codes:

Many building codes and regulations mandate the installation of backflow preventers in residential properties. These codes are in place to protect public health and ensure that water supplied to homes meets strict quality standards. Compliance helps prevent potential health hazards associated with contaminated water.

  • Diverse Residential Applications:

Backflow preventers are installed in various areas of residential plumbing systems, including irrigation systems, boilers, and fire sprinkler systems. These devices are tailored to specific applications and help maintain the quality of water throughout your property.

  • Preventing Backsiphonage:

Backsiphonage is a situation where a negative pressure in the water supply system causes water to be drawn backward into the public water system. This can occur during events such as water main breaks or firefighting activities. The backflow preventer acts as a defense mechanism against backsiphonage, preventing the potential entry of contaminants into the public water supply.

  • Ensuring Safe Water for Everyday Use:

From cooking to bathing, and from washing dishes to drinking water, the backflow preventer ensures that every drop of water flowing into your home is free from harmful contaminants. It provides peace of mind, knowing that the water you use for daily activities is safe and meets the highest standards of water quality.

  • Maintenance of Public Health Standards:

Public health authorities emphasize the importance of maintaining the quality of water in the entire water distribution system. The installation of backflow preventers in residential properties contributes to the overall integrity of the public water supply, protecting not only your household but the entire community.

Your house has a backflow preventer as a proactive measure to ensure the safety and purity of the water you use. It’s a critical component of modern plumbing systems, aligning with stringent regulations and standards aimed at protecting public health and maintaining the integrity of the water supply infrastructure.

A backflow preventer, commonly referred to as a backflow valve, comes in various designs, each tailored to specific applications and degrees of protection. The appearance of a backflow valve depends on its type, but generally, it consists of a device with distinct components designed to allow water to flow in one direction while preventing backflow. Let’s explore the common types and their visual characteristics:

  • Pressure Vacuum Breaker (PVB):

A PVB is often installed above ground and has a distinctive shape resembling an inverted “U.” It typically consists of a valve body with two check valves and an air inlet valve. The air inlet valve is positioned at the highest point of the device to prevent water from siphoning back into the main water supply.

  • Reduced Pressure Zone Device (RPZ):

The RPZ is a more complex backflow preventer with a larger, bulkier appearance. It features two independently acting check valves, a hydraulically operating relief valve, and a zone located between the check valves where water pressure is reduced. The relief valve opens to the atmosphere if backflow occurs, preventing contaminated water from entering the public water supply.

  • Double-Check Valve Assembly (DCVA):

The DCVA is a compact backflow preventer with two check valves arranged in series. It often resembles a compact metal or plastic housing with two valve bodies and test cocks for periodic testing. The test cocks allow for the verification of proper functioning without disassembling the unit.

Atmospheric Vacuum Breaker (AVB):

An AVB is a simpler, compact device often used in low-hazard applications. It consists of a single check valve and an air vent that opens when the water supply is turned off, allowing air to enter and prevent backsiphonage. Visually, it is relatively small and may be installed above ground on plumbing fixtures like outdoor faucets.

  • Dual Check Valve:

This is a basic backflow prevention device consisting of two check valves arranged in series. It is typically smaller in size and may be used in low-hazard situations. Its appearance is straightforward, with two valves housed in a compact unit.

  • Detector Check Valve:

In some settings, a backflow preventer may also include a detector check valve. This valve contains a sensing mechanism to detect any anomalies in water flow, providing an added layer of protection. Visually, it shares similarities with other backflow preventers but may have additional components for detection purposes.

Visual inspection alone may not be sufficient for ensuring the proper functioning of a backflow preventer. Periodic testing and maintenance, often conducted by certified professionals, are essential to verify that the device is in good working condition and providing the necessary protection against backflow. The appearance of the backflow preventer is just one aspect; understanding its internal components and how they function is crucial for ensuring water safety in various plumbing applications.

    My water heater cracked, I called several companies to get quotes. The prices I got from the other companies even with me purchasing the water heater myself was crazy high! Joey came out from Knockout and with me getting the water heater myself they're price was 1/3 the price of the others. Joey pointed out that the water heater pan should have been 'piped outside' to prevent the water pouring out in the garage, I said yes, do it, how much, it was already included in the price he gave me! In the process of replacing it, they discovered the platform was rotted, from the pervious water heater/owner. Joey got a hold of Chris at Best Option Restoration, who arrived within the hour, and discovered that the walls were also water damaged. So this meant everything had to be torn out surrounding the water heater, and meant the water had to be shut off. Joey ran out and got supplies to make a 'make sift' situation, so we could have water till the demo was completed. They came right back as soon as the demo was completed to install the new water heater. Knockout Plumbing turned a real nightmare ordeal, to painless! Awesome, knowledgeable, professional, and most importantly in these types of situations, very prompt!

    Thanks to Knockout Plumbing and your very helpfult technician in getting all of our plumbing needs resolved, and at a very reasonable price.

In less than 3 hours, every item on the list was operating as new and at a very nominal fee! I highly reccommend Knockout Plumbing to anyone.Larry w.

    I recently had Knockout Plumbing come out to my home to replace two toilets. I first spoke with Christin who was very professional and pleasant. She explained how everything would work and even got me on the schedule in the same day! Joey came out and did the installation. He explained everything to me before beginning, and before I knew it, he was done. I will definitely be using Knockout Plumbing in the future. If you need a plumber, these are your guys!
    Chris Fantozzi
    Went to a homeowners home for a burst water heater as a restoration expert, and needed a plumber to come out and handle the initial source to be able to handle the residual damage to the home. I called knockout and they were there a half hour later and took care of my homeowner. The homeowner was very pleased and said they will continue to use knockout for future endeavors. Very pleased.

    Needed a plumber in a hurry. THEY called us back. I'm very impressed. Most would have made us call them back. They came the same day and saved the day for us. I think Dan helped us (joked about being the "old guy" of the group.) Fast friendly and efficient. I'm so glad they called back.

    Laurie Toner
    My story is a simple one. Im an old lady on disability who woke up to a clogged toilet. I was out of money until my next pay day. After explaining my situation to 5 plumbing companys i still was turned down. Knockout was the only company that would fix my plumbing BEFORE i could pay. They were more than gracious with their help and promptly got me on their schedule the very next morning. Again i say thank you for working with me. L. Toner
    Steven Feld

    donna phillips
    CALL THEM FIRST! Fast and very accommodating! I called in the morning because my AirBnb guest informed me that the garbage disposal was backed up. The scheduler was so nice; she scheduled me for same day service! The technician Joey called to say he could come early, which normally would have been great, but I live 40 minutes from the condo. (My guest was not expecting him for 2 hours) He agreed to see if my guest was home. Joey knocked, but the guest didn't answer, so he agreed to come back at the originally scheduled time.When Joey returned, the guest still didn't answer the door, but Joey was so patient, he waited for me to unlock the door remotely and then went in, fixed the disposal, and was outta there in 10 minutes! I cannot say enough how much their flexibility meant to me.** Side note, I originally had scheduled with a different "large" company, and I rescheduled my clients TWICE to meet him out there, and he never showed!! 😡
    Dolly Cutruzzula
    I was in a desperate situation and found a referral to this company, and they did not disappoint! Their customer service is spot on, and Joey was prompt, professional and honest! Will definitely recommend this company!

He went above and beyond.I would definitely use Knockout Plumbing in the future and ask for Dan! Thanks again.

    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
    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

    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!

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

    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!

    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.

    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.

    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.

    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.
