High water pressure is major cause of leaks, pipe damage, and wasted water. This water pressure is often well over 100 psi, and too often over 150 psi. However, the maximum recommended pressure for a residence is 80 psi.

Is 95 PSI water pressure too high?

But 95 psi is not exceptionally high, and I can tell you millions of homes have had water pressure above the recommended mark for decades, suffering no ill effects. So I would consider it a very low risk at 95 psi. Adding a pressure-reducing valve without an integral bypass makes the plumbing system “closed.”

What is good water pressure for a house?

Residential water pressure tends to range between 45 and 80 psi (pounds per square inch). Anything below 40 psi is considered low and anything below 30 psi is considered too low; the minimum pressure required by most codes is 20 psi. Pressures above 80 psi are too high.

Do I need a pressure relief valve?

Installing a pressure relief valve (PRV) before your tankless water heater is not only required in some regions depending on where you live, but is also a very important safety feature. The increased water pressure opens the pressure relief valve and water can escape to the exterior.
