Frequently Asked Questions

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 install the Fluidmaster 747 Fill Valve Service Kit?"
A. To install the Fluidmaster 747 Fill Valve Service Kit, you need to first turn the water supply to the toilet off. Using your fingers, turn the cap (usually blue but not always) connected to the copper (or plastic) riser tube a quarter of a turn counterclockwise to release the cap from the float assembly. A wrench should not be required. Once the cap is disconnected from the tabs keeping it in place, pull the float assembly straight off. Align the replacement Fluidmaster 747 fill valve service kit (float assembly) up and push it back into the cap and turn the cap clockwise a quarter of a turn until it tightens onto the tabs on the float assembly (fill valve service kit). Turn your water back on and check for leaks.
