Protect the Plumbing System From Excessive Water Pressure
A PRV controls the pressure entering a home or business from the public water supply. When pressure is too high or the valve is failing, pipes, fixtures, toilets, water heaters, appliances, and supply connections can experience unnecessary stress.
The current service page supports pressure testing, valve selection, installation, replacement, adjustment, and code checks. The new page should connect PRV work to expansion tanks, water heaters, leak prevention, and main-line service.

Signs You May Need Pressure Reducing Valves
These signs can indicate that pressure reducing valve service or further diagnosis is needed.
Very High Pressure
Fixtures deliver unusually forceful flow or pressure readings exceed the desired range.
Pressure Fluctuation
Pressure changes noticeably throughout the day or during fixture use.
Banging or Water Hammer
Pressure and fast-closing valves can create noisy pipe movement.
Recurring Fixture or Supply Leaks
Faucets, toilets, hoses, and appliance connections fail repeatedly.
Water-Heater Relief Discharge
Pressure or thermal expansion may be affecting the system.
Low Pressure After the PRV
A failed or restricted valve can reduce flow throughout the property.
Old or Corroded Valve
The installed PRV no longer adjusts or holds pressure consistently.
Common Causes
The underlying cause determines the appropriate service, repair, or replacement approach.
- High municipal supply pressure
- High municipal supply pressure
- Aging or worn PRV internals

How Specialty Diagnoses the Issue
Specialty Plumbing follows a structured diagnostic process before recommending the work.
- 1Measure incoming and downstream pressure.
- 2Compare static and flowing conditions.
- 3Inspect the valve for age, corrosion, leakage, restriction, and adjustment response.
- 4Evaluate whether thermal expansion is contributing to pressure spikes.
- 5Recommend adjustment, replacement, or related system correction.

VIEW ALL SERVICE AREASFrequently Asked Questions About Pressure Reducing Valve Service
What does a pressure reducing valve do?
It reduces and regulates the pressure entering a property from the public water supply.
How do I know whether my pressure is too high?
A plumber can measure static and flowing pressure. Repeated leaks, forceful flow, or relief-valve discharge can also be warning signs.
Can a PRV be adjusted instead of replaced?
Sometimes, if the valve is serviceable and responds correctly. Aging, leakage, restriction, or failed adjustment may require replacement.
Can a bad PRV cause low pressure?
Yes. A failed or clogged valve can restrict flow to the entire property.
Why do I need an expansion tank after installing a PRV?
A PRV can create a closed system. Heated water expands, so thermal-expansion control may be required.
Will a new PRV stop water hammer?
It may help when excessive pressure contributes, but pipe support, fixture valves, and arrestors may also need evaluation.
Do commercial properties use PRVs?
Yes, but sizing and system configuration may be more complex.
How often should a PRV be checked?
There is no universal interval; check it when pressure symptoms appear or during relevant plumbing inspections.
