    I have 3 toilets with extremely sticky Mansfield Flush Valves on 160 Toilets after 6 years.

    I read somewhere that this is caused by suction and bad gaskets after use of chlorine in the tanks. (My wife does that before we leave on trips due to growth in the tanks) ?

    1. Should I replace the whole Valve or just the Gasket ? :confused:
    2. If replacing the parts, Should I use :confused:
    A. Fludimaster
    C. Replacement Mansfield mechanisms ?
    D. Other recommendations.

    Thanks for your recommendations.

    Repair parts for internal seals of a fill valve are generally not'd need ones made specifically for that valve. If a toilet is not designed for dual flush, don't try to make it into one as it rarely works well. If your toilet can accept a replacement fill valve, I'd use either a Korky Quiet-Fill or a Fluidmaster and replace the whole valve. If you can get exact replacement parts for the existing valve, using those should fix it. Keep in mind that long-term use of chlorine products in the tank WILL destroy all rubber parts - not only gaskets but the flapper valve and maybe other seals in the toilet.

    The poster is saying "flush valve". Does he mean "fill valve"? Or not?

    "Sticky" I thought meant that it was hard to flush, so maybe we need some clarification about what the problem is.

    Replace it with Korky products. Korky 528 Fill Valve and Korky Plus flapper in the proper size.

    And tell your wife to knock off the Clorox Tablets. Particularly if you're doing it while being away for a long time. The tablet instructions themselves say that if the toilet isn't flushed X times per day,t he concentration of the bleach solution will be damaging. And that's from Clorox.

    If she really wants some BOWL cleaner to be auto-dispensed (no need to worry about the appearance inside the tank...I mean really NO need), she can get one of those systems that runs the refill water over a tablet in a box and then down the refill tube. That keeps it away from all the rubber seals.

    They make replacement seals for the flush valve of the 160 Mansfield.
    It's a pretty simple repair.

    Thanks for the advice.

    Replaced the 3 Red Washers and works fine now that I got the minor leaks stopped.
