Reduced Pressure Zone (RPZ) Assemblies

Expert RPZ Valve Inspections and Code-Compliant Installations

RPZ valves — also known as Reduced Pressure Zone assemblies — are mission-critical devices in any plumbing system where contamination risks are present. These assemblies are specifically engineered to prevent backflow caused by pressure differentials that occur during main breaks, hydrant use, or sudden demand spikes. Without an RPZ valve in place, hazardous substances such as fertilizers, pesticides, industrial cleaning agents, or bacteria-laden water can reverse-flow directly into the potable water system. That’s why RPZs are required by law in all cross-connection scenarios where the public water supply could be compromised.

Our licensed technicians at Drain & Plumbing Services provide precision installation and annual certification of RPZ valves for both residential and commercial systems. Whether you're managing a healthcare clinic off Milwaukee Avenue, a food processing facility near Wolf Road, or a retail complex along Lake Cook Road, we ensure your backflow assemblies are installed correctly, tested on schedule, and meet all municipal and IEPA standards. From permitting and inspection paperwork to equipment replacement and emergency servicing, we handle it all with the accuracy and professionalism Wheeling property owners depend on.

DPS Will Help You With Backflow Inspection and Paperwork

In Wheeling and throughout Lake and Cook Counties, the use of RPZ assemblies is regulated under Illinois EPA standards and enforced locally through municipal plumbing inspections. Our certified plumbing technicians handle every step of the process — from initial evaluation and RPZ selection to precise installation, testing, and annual re-certification.

We also submit all necessary documentation directly to your city or village water department, taking the guesswork off your plate. Whether you’re upgrading an outdated backflow preventer or installing a new assembly for a commercial build-out, we ensure complete compliance, safety, and efficiency.

Gwen

Sink/ Faucet/ Bathtub Repair Buffalo Grove, IL Happy to leave a good review for a great plumber! Mike from Drain & Plumbing Services saved my day (and my condo) when he came out to diagnose the leak in my shower. I expected to have to break my tile and shower apart (based on another company's recommendation) - but Mike was able to remove and replace my cartridge the same day, stopping the leak. I couldn't have asked for more!

Nancy

Water Filtration System Deerfield, IL I had a problem with our commercial coffee maker that had a plumbed in line and I called this morning. Within a few hours this excellent plumber came to my rescue and showed me how the plumbing worked for the machine and showed me it was working perfectly. He was kind, fast, efficient, polite, competent and overall I had such a great experience I asked him if I could leave him a good review because I felt so strongly about the excellent service I received. Going forward, I will always call this man for all my plumbing needs. He proved himself valuable today and that means something. He didn't ask me for a review - I wanted to provide it so more people would know about quality people like this man. Thank you so much for your service today.

Anne/Steven Wold

Sewer Clog Removal Deerfield, IL I needed to have my sewer rodded out every year. Last year I contacted Drain and Plumbing Services. They came out and cleaned out my sewer and I did not experience any back up problems, the whole year so I called them again. Yuri came out, and upon his suggestion last year, I chose the hydrojet system and afterwards, Yuri told me that it was very clean and that I probably would be good for two years. He was on time, explained what he was going to do, was very professional and very pleasant. He is very knowledgeable and I trust him implicitly. I would definitely recommend this company to come out and help with any plumbing problems. They are all very accommodating, especially Anna and Yuri, who I talked with, and they do an excellent job! They are my "go to" plumbing company for any plumbing needs. It is wonderful to be able to have such confidence in a service company, a rarity in today's world.

Zaneta W.

Sump Pump Replacement/ Repair Arlington Heights, IL Thank you for replacing my broken sump pump right on time before the storm. You saved my basement from major flooding. Best plumbing service in Arlington Heights!

Richard K.

Mainline Rodding Palatine, IL I highly recommend Drain & Plumbing Services. They had sent Uri to fix by sewer backup. He was at my house within an hour. He was able to clear out root in my drain in less than an hour. Other plumbers have told me I have broken pipes and need an expense cleanout install that would cost over $5K. Uri's honesty and knowledge showed me that it wasn't needed. All other plumbers have tried to make more money off me, but this company honest. This company will always be my first choice for plumbing from now on!

Sump Pump Replacement/ Repair Vernon Hills, IL Drain & Plumbing Services repaired my exterior spigot that was leaking water into my basement. They also replaced my sump pump that had gone bad including a battery backup sump pump accessory for which I requested. Everything was done professionally.

Thomas Davis

Toilet/ Sink Clog Removal Elk Grove Village, IL This company was awesome. After trying to unclog my kitchen sink for 2 days myself, I decided I needed to call a professional. After talking to more than 10 plumbing/drain companies, I chose 24/7 Drain Cleaning because they said they can come out the same day. 24/7 Drain showed up at my house within 2 hours after contacting them the same morning and unclogged my kitchen sink within 15 minutes. Without a doubt, I would call this company again if I ever run into a clogged sink I can't fix myself.

Kayla Hurst

Toilet/ Sink Clog Removal Elk Grove Village, IL I called yesterday to afternoon because our basement sink from our laundry wasn't draining. I was able to make an appt for a 2hr window for today from 9a-11a. They were right on time and went right to work. We have a 100 year old home we recently bought so I was a little nervous about the workload/price. He unclogged our sink and was able to drain it into our floor drain - which was literally all the way across the room from the sink. He was nice, super fast, knowledgeable and ridiculously reasonable. Will use again if needed! Thank you!

David Y.

Sink/ Faucet/ Bathtub Repair Winnetka, IL I am typically wary of plumbers thinking they’ll take advantage and overprice things. This is the first plumbing company I’ve worked with that felt trustworthy to me. They advertise the fact that they strive to provide good value, and that they understand customers have budgets. They did excellent work, had a sense of urgency to correct my problem and I felt very comfortable with the pricing. Feels good to now have a go-to plumber for the future.

RPZ Valve Backflow Testing Services Wheeling, IL

Certified RPZ Backflow Inspectors Near Wheeling, IL

When Are RPZ Valves Required?

Reduced Pressure Zone assemblies are required in any setting where a cross-connection could allow contaminated water to flow back into the public water supply. These high-risk scenarios include irrigation systems, fire sprinkler lines, commercial boilers, chemical mixing stations, medical equipment, and any plumbing configuration where back-siphonage or back-pressure may occur. In communities like Wheeling and throughout Lake and Cook Counties, these devices are mandated by local plumbing codes to protect the health and safety of the public.

Even small fluctuations in water pressure — due to firefighting activity, hydrant flushing, or a main break — can create the conditions for backflow. Without a properly functioning RPZ assembly in place, these pressure drops could allow dangerous substances like fertilizers, cleaning agents, or bacteria-laden water to contaminate your entire system — and in some cases, the city supply.

RPZ valves act as a physical barrier and pressure control point, ensuring flow stays safe and unidirectional.

Annual RPZ Backflow Testing Near Wheeling, IL

Under the Illinois Plumbing Code and regulations from the Illinois Environmental Protection Agency (IEPA), all RPZ backflow prevention assemblies must be tested every 12 months by a licensed and certified backflow inspector. This ensures the internal check valves, relief valves, and pressure zones are functioning as designed.

At Drain & Plumbing Services, we perform thorough testing, identify signs of wear or malfunction, and file compliance reports with local water authorities on your behalf. If your system fails, we can repair or replace the assembly promptly to prevent water service interruptions or legal penalties. We proudly serve residential, commercial, industrial, and municipal clients in and around Wheeling, IL.
