Q:Does the fill valve pin poke through the bottom of this seal? Just changed it and pin sticks through and water keeps going , doesn't shut off.
by|Dec 1, 2023
1 Answer
Answer This Question

A:  yes, the pin goes through the middle of the seal. If the fill valve is not shutting off completely flush it out to clear it from any debris that might have come from the pipes that may be obstructing the seal from closing.

    Q:My tank fills so that water goes into the overflow. This seal was changed and issue not resolved . Does it mean the valve needs to be replaced
    by|Dec 1, 2023
    1 Answer
    Answer This Question

    A:  You may just need to break in the seal as they sometimes sit on the shelf too long and stiffen up. Soak the seal in hot tap water for a couple minutes and then bend and flex seal to help soften it up and reinstall in the cap.

      Q:Will the fluid master 242 fill valve seal fit the Kohler k4421 toilet
      by|Sep 16, 2023
      1 Answer
      Answer This Question

      A:  The model you provided for the kohler does not let is know what fill valve model number you have. If you have a Fluidmaster fill valve currently in there then yes this seal will replace it. If you have a different brand fill valve then no as it's proprietary to our brand only.

        Answer This Question

        A:  No it won't. The issue you have is a leak within the components in the middle of your tank.

          Functions perfectly in the FluidMaster 703a series fill valve in my Glacier Bay toilet. Sadly, the rubber doesn't do well with my water, so I have to replace it every year or so. Luckily, it's a lot cheaper than replacing the whole fill valve. I tried coating it in silicone grease, hopefully it helps it last a little longer.

                  Bought it, replaced a broken one that kept my toilet constantly filling. Replaced in less than 2 minutes and everything is back to normal.

                      Water continues to run in the tank on occasion. For a few seconds. Mostly this product did the trick.

                        The new seals cured the problem in 4 toilets in the house and adjacent apartment. I told your associate my problems with the tiolets and he recommended replacing the valve seals. Excellent advice!

                          It was a relief to find this solution to enable my toilet tank to fill vice replacing the entire fill valve assembly.
