RV plumbing systems are usually tested to a pressure of about 100 to 125 pounds per square inch (psi), but to prevent warranty problems, RV manufacturers may recommend only 40-50 psi. If your water supply pressure is approaching 100 psi, you are risking an expensive failure of your plumbing system. You should limit your pressure to 60-65 psi to be safe, and to do that, you can install a pressure regulator. The new U.S. Solid Water Regulator Valve will keep your water pressure at a safe level. Our water regulators are made using a hot casting process making them lead free. Each regulator is tested and contains lead well under the NSF lead-free requirement of 0.25%.
