I have a toilet that constantly fills every five or ten minutes. I have replaced the fill & flapper valves but the problems persist. - Losing Water in Newport.
Leaks at the Flush Valve are possibly caused by a damaged flush valve seat which may have a hole or the rim is pitted or cracked. The seat is the large drain hole at the bottom of the tank. A temporary repair may be to sand the seat with a steel wool pad or wet/dry sandpaper. This will remove the calcium build-up. If the seat is damaged, replacing the seat will be the next option. “Fluidmaster, Inc” makes a Flusher Fixer Kit that can be cemented directly on top of your old worn flush valve seat. This is a quick fix that may not work on all toilets. If the seat kit does not work, you will need to replace the valve seat. This can be accomplished by removing the tank from the base of the toilet: Turn off the water to the fill valve, disconnect the water line and remove any water from the tank. Unscrew the two or three brass bolts under the tank and carefully lift off. Once the tank is removed, turn it upside down. Remove the rubber “Spud” washer from the tank. Spin the large nut from the threads and then push the valve seat through the tank. Reverse the procedure when installing the new valve seat. Always install a new “Spud” washer and new brass bolts and washers. Be sure your toilet tank is installed level, as this will aid in operation.
