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 you replace the 'seal' on the older style Champion®4 flush valve?"
A. The following seal replacement directions are for the original Champion®4 flush valve assembly #3175.002:
First, shut off the water supply to the toilet and flush the toilet to empty the water out of the tank. Disconnect the flush valve chain from the trip lever. Lift up the flush valve cylinder and remove the old seal by pulling it out of the groove and sliding it over and up the cylinder. Install the new seal by sliding it down over the flush valve cylinder. Make sure it is seated into the groove. Reattach the chain to the trip lever. Turn on your water supply. Check to make sure the seal is working correctly.
