Do I Need a Pressure-Reducing Valve?
If you've noticed banging pipes, dripping faucets, running toilets, or appliances that don't seem to last as long as they should, your home's water pressure could be the culprit. Many homeowners don't realize that excessively high water pressure can quietly damage plumbing fixtures and appliances over time.
A pressure-reducing valve (PRV) is designed to regulate the water pressure entering your home, helping protect your plumbing system and improve its longevity.
What Is a Pressure-Reducing Valve?
A pressure-reducing valve is installed on the main water line where it enters your home. Its job is to reduce incoming water pressure from the municipal water supply to a safe, consistent level for your plumbing system.
Most homes perform best with water pressure between 50 and 70 PSI. Water pressure above 80 PSI is generally considered too high and can increase wear on your plumbing.
Signs You May Need a Pressure-Reducing Valve
Your home may benefit from a PRV if you notice:
Water pressure that feels unusually strong.
Pipes that bang or make loud noises when fixtures are turned off.
Faucets that drip even after replacing washers or cartridges.
Toilets that constantly run or require frequent repairs.
Water heater relief valve discharging water.
Washing machine hoses or dishwasher supply lines failing prematurely.
Frequent plumbing leaks or fixture failures.
Why High Water Pressure Is a Problem
While strong water pressure may seem convenient, it puts added stress on every part of your plumbing system. Over time, excessive pressure can shorten the life of:
Water heaters
Faucets
Toilets
Ice maker supply lines
Washing machine hoses
Dishwashers
Pipe fittings and valves
Installing a pressure-reducing valve can help prevent costly repairs while extending the life of your plumbing system.
How Do You Know Your Water Pressure?
The easiest way to check your home's water pressure is with a pressure gauge that attaches to an outdoor hose bib or laundry faucet. If the reading is consistently above 80 PSI, it's a good idea to have your plumbing system evaluated.
A licensed plumber can also test your pressure and determine whether a pressure-reducing valve is recommended.
Can a Pressure-Reducing Valve Be Adjusted?
Yes.
Most PRVs are adjustable, allowing a plumber to fine-tune your home's water pressure. If your existing valve is old, leaking, or no longer regulating pressure correctly, it may need to be repaired or replaced.
