Water Pressure Regulation & PRV Installation

Water pressure that’s too high doesn’t announce itself with a leak right away — it quietly stresses every supply line, fixture seal, and appliance connection until one of them fails. MQ Plumbing tests, diagnoses, and installs pressure regulation systems — pressure reducing valves and expansion tanks — for homes and businesses throughout Mint Hill, Charlotte, and the surrounding metro.

Pressure Reducing Valve (PRV) Installation

Regulates incoming municipal supply down to a safe, consistent range, sized and set for your home's actual demand.

Expansion Tank Installation

Absorbs the pressure spike created by thermal expansion in a closed plumbing system, required in most jurisdictions once a PRV or check valve is in place.

Well System Pressure Tanks

Pressure tank installation and sizing for private-well properties, coordinated with well pump work.

Whole-Home Pressure Testing

An on-site pressure reading and diagnosis before we recommend anything, so the fix matches the actual cause.

Normal vs. Problem Pressure

Residential water pressure should run between 40 and 80 PSI. Most municipal connections across the Charlotte metro deliver supply at 60 to 100 PSI, which means a meaningful share of homes here are operating above the safe range without a pressure reducing valve to bring it down. Above 80 PSI, a home’s plumbing system is under continuous stress — not enough to cause an immediate failure, but enough to shorten the life of every fixture and appliance connection over years.

Not sure if your pressure is in range?

We test on-site and give you a straight answer before recommending anything.

Normal vs. Problem Pressure

Why a PRV Is a Standard Install, Not an Upgrade

A pressure reducing valve isn’t an optional add-on — in most jurisdictions in our service area, it’s required whenever a backflow prevention device or check valve creates a closed system, because that combination traps thermal expansion with nowhere to go. A properly sized and set PRV protects every pipe, fixture, and appliance in the house from years of excess pressure, which is a meaningfully cheaper problem to prevent than to repair after the fact.

 Trustindex verifies that the original source of the review is Google. Max and his crew did an excellent job replacing my water heater. It was in tight quarters and they protected walls and flooring. The installation of the piping was nice and clean. They did a good job of cleaning up when they were finished.

 Trustindex verifies that the original source of the review is Google. We recently completed our basement project and hired MQ Plumbing for our full bathroom and whole-house water filtration system, and they did an outstanding job. The bathroom turned out beautiful with amazing attention to detail and high-quality workmanship. Our family is extremely happy with the final result. The whole-house Aquasana filtration system was also installed very neatly and professionally with a super clean and organized piping layout. Max was one of the best contractors we worked with during this project. He is professional, patient, and truly listens to every detail before starting the work. Unlike some contractors who become less responsive once the project begins, Max stayed responsive throughout and even came back twice after completion to make sure there were no leaks and that we were fully satisfied. You can clearly see that he takes pride in his work and cares about customer satisfaction. I would highly recommend MQ Plumbing and would definitely call Max again for any future plumbing needs.
