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
What's included:
  • One pressure regulator (3/4 in.)
Install notes:
  • 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
