Please note: Some older models of the 6003/6004 used a different set of replacement parts with a tank ball as opposed to a flapper. Unfortunately, those older-style parts for have been discontinued and have not been available for quite a while, but we do have an example of an older parts guide for you to look at if you're curious about how the internal parts of this toilet have changed.
Q. "I installed a new fill valve and it will not shut off completely. The water has reached the float, and the float appears to close the valve. How come the fill valve continues to run?"
A. 1) It could be there may be dirt or debris between the plunger and the seat or in the incoming line of the valve. It is best to turn your water off, remove the plunger from the fill valve. Turn the water back on for a few minutes to flush any dirt or debris out of the valve and the water line. During this process, you may want to cover the fill valve with your hand or a cup to prevent water from spraying you or your ceiling.
2) It may be the float needs to be adjusted. Do not bend the float rod. Adjust the plunger fulcrum arm. To lower the water level, place a screw driver under the middle of cross lever and above the support of the float rod and press firmly on the float rod next to the fulcrum.
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 chemical bowl cleaner some flappers won't even last one year. However, some toilet bowl cleaners isolate cleanser from the internal workings of the toilet therefore, maximizing the life of your toilet parts. 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.
