    What to do if Watts Premier Water System filter housing leaks?
    • M

      If water leaks from the blue/white filter housing: * Ensure the bowl is properly tightened. * If there is a kinked o-ring: Turn off the water supply and release the pressure. Replace the o-ring if necessary. Lubricate it and make sure it is seated properly in the filter bowl before reinstalling.

    Why is my Watts Premier Water System producing water slowly?
    • W
      weberbradleyAug 3, 2025
      Several factors can cause low or slow water production. Check the following: * Ensure incoming water pressure is at least 40 psi. If it's too low, Watts Premier sells a booster pump. * Confirm the water supply is on and the Adapta Valve is fully open. * Inspect tubing for crimps and straighten or repair them. * Replace clogged pre-filters. * Replace the membrane and Flow Restrictor if the membrane is fouled.

    What to do if Watts Premier Water System constantly running and won't shut off?

      If your system won't shut off, there are several potential causes: * Low water pressure: Ensure a minimum of 40 psi incoming water pressure. * Crimp in supply tube: Inspect the tubing and straighten or repair as necessary. * High water pressure: Verify that the incoming water pressure does not exceed 80 psi. A pressure relief valve may be required. * High pressure in: Empty the storage tank of water and set the tank air pressure to 5 psi.

    Why does my Watts Premier Water System faucet leak from the airgap feature?
    • D
      David PierceAug 12, 2025
      Airgap faucet leaks can occur due to: * A crimp in the drain line: Check the tubing. * A restriction in the drain line: Straighten all drain lines, clear any blockages, and cut off any excess tubing. * A clogged drain tube: This is often caused by the dishwasher or garbage disposal. Disconnect the 3/8" black line at the drain, clean it out with a wire, and then reconnect it. Blowing air through the line may not always remove the clog.

    Why is my Watts Premier Water System making noise from the faucet or drain?
    • B
      Bradley DunnAug 15, 2025
      Noise issues can stem from a few sources: * Air gap faucet: The sound is inherent with air-gap faucets. * Location of drain saddle: Check the diagram for proper location of the drain saddle. * Restriction in drain tube: Clear any blockage that may be caused by debris from the garbage disposal or dishwasher. * High water pressure: A pressure regulator is required if the pressure exceeds 80 psi.

    Why is there a small amount of water in my Watts Premier Water System storage tank?
    • A
      Annette FullerAug 20, 2025
      A small amount of water in the storage tank could be due to: * System just starting up: It normally takes 6-10 hours to fill the tank. Low pressure and/or temperature can drastically reduce production rate. * Low water pressure. * Excessive air in the tank bladder: Tank pressure is set at the factory and should be 5 psi when empty. Add air if below 5 psi and bleed air if above 5 psi. Check only when the tank is empty.

    Why is the water from my Watts Premier Water System milky colored?
    • C
      Connie MccarthyAug 26, 2025
      Milky colored water is often due to air in the system. This is normal when initially starting up the RO system and should disappear within 1-2 weeks of normal use. If it reoccurs after filter changes, drain the tank 1 to 2 times.
