RPZ / Backflow Testing & Installation


Commercial buildings are required to protect their potable water supply from contamination caused by backflow. An RPZ (Reduced Pressure Zone) or backflow preventer is a critical safety device that stops polluted or non-potable water from flowing back into the public water system.


We provide certified RPZ and backflow testing, installation, repair, and replacement for commercial properties. Our team ensures all devices are installed correctly, tested to local and state requirements, and fully compliant with plumbing and water authority regulations.

Our RPZ / Backflow services include:

RPZ & backflow preventer installation

Device replacement

Annual and required backflow testing

Compliance documentation & test reporting

Coordination with local water authorities

New construction & existing building systems

Proper backflow protection is not optional—it’s required for many commercial applications including irrigation systems, fire protection, boilers, and specialized equipment. We help business owners, property managers, and contractors stay compliant while keeping water systems safe and reliable.

Affordable and professional. What more do you need?

Oh yeah...being on-time and cleaning up well afterward was a real treat. Having NRH's number in my phone is great insurance. Will definitely use again.

The level of service I received with the entire team at NRH was absolutely stellar!

I’m glad I called them for a second quote as I discovered the other company was charging me 3X higher!Dave with NRH provided options that fit my situation, the pricing was FAIR and reasonable, plus he was able to work with what was already done. Dave gave me peace of mind when I needed it most.Thank you for being the local plumbing company that I can count on! Honest. Reliable. Homegrown

Dave with NRH plumbing was very helpful in solving our plumbing problems.

He goes the extra mile and did a great job!


Angie T.

New water softener and whole house filter. No pressure, friendly

and spent time explaining things and educating us as well as answering other unrelated plumbing questions. Timely and efficient install and no hiccups. Thanks Dave and Drew!

My laundry room floor drain was clogged. Sam and John came out to fix the problem

and they were so friendly and professional. I had tried to fix the problem myself with a snake, which actually did fix some of it, but they made sure it was completely fixed. John gave me some advice on what to do so it won't happen again, and left me with a can koozie and a $25.00 gift card.

If I ever hear of anyone needing plumbing services, I would be happy to recommend NRH Plumbing.

about the work they were doing along the way. We had a follow up question after they had finished the job and they were very responsive and nice.
