Replacing a Water Pressure Reducing Valve in Broken Arrow

Homeowners in Broken Arrow noticed a water hammer sound and needed a plumbing diagnosis for their water pressure system.

Our crew diagnosed the issue and determined the existing pressure reducing valve needed to be replaced.

Our plumber replaced the old valve using a new three-quarter-inch PRV double-sided union, along with propress adapters, expansion adapters, expansion tees, expansion nineties, an expansion ball valve, and male expansion adapters.

Casey and Jared were assigned to this Broken Arrow visit. The call was to diagnose water hammer, and the pressure reducing valve was located in the master closet. The work description identifies the existing valve as starting to fail and hammer. The customer gave Casey verbal approval for the replacement. There is no recorded before-and-after pressure reading in this job, so we are not attaching a guessed pressure number to the repair.

The replacement scope described two possible connection paths. First, the plumber would try to unthread and remove the existing PRV. If the new valve lined up and used the same thread pattern, it could be installed in the old valve's position. The union threads needed to fit correctly. This was a fit-and-connection check, not simply a matter of choosing a valve that looked similar from outside the wall.

If the new valve was different in size, the approved description allowed for rebuilding the manifold for the shutoff and PRV. That alternate scope involved cutting out the old pressure regulator and the old shutoff valve, then using suitable fittings to install both replacements. The description presented that as a conditional route with additional work, not as proof that every piece of the manifold ultimately had to be rebuilt.

The parts notes identify a three-quarter-inch, double-sided-union PRV. The list also includes two three-quarter-inch press-to-expansion adapters and two half-inch press-to-expansion adapters. Two three-quarter-by-half-by-three-quarter expansion tees were listed, along with one half-inch expansion elbow and four three-quarter-inch expansion elbows. A three-quarter-inch expansion ball valve and two three-quarter-inch male expansion adapters were also included in the material notes.

Those sizes help explain why the connection plan mattered. The work involved the regulator, its union connections, the shutoff arrangement and transitions between existing plumbing and expansion fittings. It was not a faucet cartridge repair or a replacement of all the water piping in the home. The job-specific material notes describe the components prepared for work at this one valve location.

The test sequence in the scope was to restore water to the house and check for leaks and proper operation after installing the new valve. If the manifold-rebuild route was needed and the connections passed those checks, the description also called for putting the drywall back in place. We are keeping that conditional wording because the description does not identify which connection route was used in the final installation.

A failing pressure reducing valve can cause water hammer noises and improper water pressure throughout your home plumbing system.
