Is Your Home's Water Pressure Too High?
A pressure reducing valve (PRV), also called a water pressure regulator, controls the incoming water pressure from the municipal water supply before it reaches your home's plumbing system.
When a PRV begins to fail, water pressure may become too high, too low, or inconsistent. Excessive water pressure can contribute to leaks, noisy plumbing, fixture problems, and unnecessary wear on your water heater and other plumbing components.
9th Inning Plumbing can test your home's water pressure and determine whether your PRV needs adjustment or replacement.
Signs Your Pressure Reducing Valve May Be Failing
High Water Pressure
Water pressure that is consistently higher than it should be.
Fluctuating Pressure
Noticeable changes in pressure when using faucets, showers, or fixtures.
Noisy Plumbing
Banging, humming, or other unusual plumbing noises can sometimes accompany pressure problems.
Leaking Fixtures
Excessive pressure can place additional stress on faucets, valves, supply lines, and other components.
PRV Won't Hold Adjustment
If pressure continues to rise after the regulator is adjusted, the valve may need further evaluation or replacement.
Professional PRV Replacement
When replacement is necessary, 9th Inning Plumbing can remove the existing pressure regulator, install a properly sized pressure reducing valve, and test the system after installation.
We check the incoming pressure and adjust the new PRV to provide appropriate operating pressure for the home.
Services include:
PRV testing • PRV replacement • Water pressure adjustment • Water pressure troubleshooting • Main shutoff and pressure regulator evaluation
Expansion Tank Installation & Replacement
Protect Your Plumbing from Thermal Expansion
When a PRV or other backflow-prevention device creates a closed plumbing system, water expanding as it heats can increase pressure within the system.
A properly sized and charged thermal expansion tank provides space for that expanded water and helps manage pressure changes associated with the water heater.
9th Inning Plumbing provides expansion tank installation and replacement as part of our water pressure and water heater services.
Services include:
Expansion tank installation • Expansion tank replacement • Tank pressure adjustment • System pressure testing

Frequently Asked Questions
FAQs
What does a pressure reducing valve do?
1
A pressure reducing valve regulates incoming municipal water pressure before the water enters your home's plumbing system.
How do I know if my PRV is bad?
2
High, low, or fluctuating water pressure and a regulator that no longer maintains its adjustment can indicate a PRV problem. Testing the system pressure is the best starting point.
An expansion tank helps accommodate the increased volume created when water is heated in a closed plumbing system.
