Pressure Reducing Valve Replacement done right the first time

What's different about plumbing in Tempe
- Water: Tempe water comes from the Salt and Verde rivers and the CAP canal, and it is hard — typically about 13–16 grains per gallon. Scale builds up fast in water heaters and tankless units.
- Housing & pipes: Many 1950s–60s homes near ASU and in Maple-Ash still have cast-iron drains or Orangeburg sewer lines. Orangeburg is a tar-paper pipe that sags and collapses with age.
- Rentals: Tempe has a lot of student and rental housing. We schedule around tenants and send photos and written quotes straight to landlords and property managers.
From Downtown Tempe, Maple-Ash, South Tempe to the rest of Tempe, we handle PRV replacement every week. Flat-rate quotes go in writing before any work begins, and a real, Arizona-licensed plumber — never a sales rep — diagnoses the problem in your home.

Homeowner guide
Planning your prv replacement service in Tempe
Signs to watch
Banging pipes, a water heater relief valve that drips, toilets that run or refill on their own, faucets that spit, repeated supply line failures, or pressure that surges and drops are classic signs of a failing pressure reducing valve. A gauge on an outdoor hose bib reading over 80 psi confirms the valve is no longer holding pressure.
Before the appointment
Locate the main shut-off and the PRV, usually near where the main line leaves the ground at the front of the house, and clear plants or stored items around it. Plan for the water to be off for about two hours, and let us know if your water heater relief valve has been dripping or if you have a softener or leak-detection valve on the main.
After the work
We set the new valve to 55–65 psi, confirm it at a fixture, and check that the pressure holds without creeping up. Because a PRV creates a closed system, we also verify the water heater expansion tank is present and charged. A quick gauge check once a year catches a failing valve before it damages fixtures.
Homes across Tempe vary in age, piping material, pressure, fixture layout, and prior repairs. We diagnose those conditions on site, explain practical options, and provide a flat written quote before work starts. The goal is a durable repair or installation—not a one-size-fits-all recommendation.

FAQs
PRV Replacement questions from Tempe homeowners
What water pressure should my home have?
Arizona code caps household pressure at 80 psi. In Tempe we set most homes to 55–65 psi — strong showers without stressing the water heater, toilets and appliance hoses.
How do I know my PRV is failing?
Banging pipes, a dripping water heater relief valve, toilets that refill on their own, faucets that spit, or pressure that swings. A hose-bib gauge reading over 80 psi confirms it.
How long does a pressure reducing valve last?
Most last 7–12 years. Hard water in Tempe scales the internal seat and spring, so valves here often fail toward the short end of that range.
How long does PRV replacement take?
Most replacements take 1.5–2.5 hours, including shutting off the main, installing the new valve, setting pressure and checking every fixture. Water is off for most of that time.
