Water pressure in Santa Ana can vary from around 50 psi to 100 psi across the distribution system. This fluctuation happens because of routine water system operations and peak water use times. Factors like building water softeners, plumbing restrictions, and point-of-use treatment devices can also influence water pressure on your property. The City can’t adjust water pressure at individual addresses. However, if you’re dealing with high water pressure, you can take steps to address it. For instance, you can install or replace a pressure regulator on your property to lower high water pressure.
