Pressure Regulator Valve (PRV) Repair & Replacement
PRV repair and replacement for Los Angeles homes u2014 protect your pipes, fixtures, and appliances from high water pressure damage.
The pressure regulator valve controls the water pressure entering your home from the city main. Most homes should be operating between 40u201380 PSI u2014 anything above that accelerates wear on fixtures, causes pipes to bang, and can damage appliances like dishwashers and washing machines. In Los Angeles, city main pressure frequently runs high, making a functioning PRV critical.
PRVs typically last 10u201315 years. When they fail, pressure either climbs too high (causing banging pipes, leaking fixtures, and appliance damage) or drops too low (weak flow throughout the house). We diagnose, repair, or replace PRVs same-day and set the output pressure to the correct range before we leave.
