This pressure regulator controls and stabilizes incoming water pressure to the appliance, helping maintain consistent operation and protect internal valves and seals. Fits systems that use a 3/4 inch inlet regulator. What it does:

• Reduces high incoming water pressure to a safe, steady level for the appliance
• Prevents pressure-related leaks, valve chatter, and premature wear on seals
• Helps maintain consistent water flow for reliable cycles and operation
• Commonly replaced when irregular pressure, humming valves, or water leaks occur

• One pressure regulator (3/4 in.)

• Turn off water supply and power to the appliance before starting; relieve system pressure first
• Inspect connection fittings and seals; use appropriate thread sealant if required by the OEM
• Tighten to manufacturer torque recommendations and check for leaks after restoring water
