    Frequently Asked Questions

    Q. "What are the most commonly replaced toilet parts?"
    A.This depends on several factors; each time you use your toilet the trip lever, flapper, and fill valve are operated. You will find, however, that the flapper and fill valve are the parts most exposed to water and will be the first ones to wear out in most cases.

    Q. "How long 'should' the parts inside of my toilet last?"
    A. That depends on a number of variables and which parts. Water quality is one of the major factors. If your water source is heavily chlorinated then many parts won't last long. Or if you have a lot of sand or grit or have a low pH or "aggressive" water source then parts simply won't last as long as the 'average' length of time. Also the quality of the parts matters. The replaceable parts such as flappers and washers/seals generally will last at least 4 to 5 years on "average." If you use a bowl cleaner some flappers won't even last one year. If your flapper has black "goo" on it then it is either due to age or quality of your water and if it feels soft then it's best to change it.

    Q. "How do I replace the seal for a Kohler canister-style flush valve?"
    A. As with any flush valve replacement/repair, you'll need to ensure your tank is emptied of water before beginning. Unhook the trip lever from the chain on the side of the canister, and remove the refill tube from the stop on top of the canister. Grasp the stem inside the canister, then turn the stop counterclockwise to remove it. Lift the canister off of the valve base, remove the old seal and slip on the new seal. Replace the canister on the valve bottom, place the stop back on the stem and turn clockwise to tighten. Remember to clip your trip lever back to the canister and replace the refill tube.
