Most homes should run between 40 and 80 psi. If a hose bib gauge reads higher, or if fixtures drip and toilets run often, the pressure reducing valve may be missing or failed. Use our water pressure check page to see where your reading falls.

Use our pressure check page with a hardware store gauge before you call. Knowing your reading tells us whether the valve is failing, missing or fine.
What we see in Upstate homes
Water pressure varies a lot across the Upstate because of elevation. Homes in low areas or near large mains can see high pressure, while hilltop homes and those near the end of a line can run low. We test before recommending anything.
Keeping it from coming back
Test pressure once a year. Valves drift over time, and catching high pressure early protects every fixture in the house.
Questions about pressure reducing valve service
What is normal water pressure for a house?
Between 40 and 80 psi is the usual safe range. Many plumbers aim for 50 to 70.
Why do I need an expansion tank?
When a pressure reducing valve or backflow device closes off the system, heated water has nowhere to expand. The tank absorbs it.
Can low pressure be fixed?
Sometimes. It can be a failing valve, clogged pipes or a supply issue. We test to find out.
