 toilet running
Author: bozat (OR)

We are having trouble with a toilet that's only 8 years old running too much. Hubby has replaced the "guts" twice and it does the weirdest thing now. Every once in a while you hear water running in it for 5 seconds or so and then it stops. Very annoying at night since it's the bathroom in the master suite and it is close enough to hear from the bedroom. Any suggestions?

After market fill valves work very well in many toilets.After market flush valves or flappers as they are commonly known,often do not.Look for a tiny amount of movement of the water in the bowl when the toilet is sitting idle, or put a few drops of food coloring in the tank while the toilet is sitting idle.If the water in the bowl changes color, the flapper is leaking.Start by making sure the chain to the flapper is loose and not interfering with it closing.Let us know and we'll take it from there.

Try to find a "Coast" brand flapper. They are blue in color and seal very well. Examine the seat on the flush valve (that the flapper closes on) for any warpage or dirt.

YES, repair the toilet properly, but without seeing it we cannot tell you HOW to do it.

I REMOVE Coast brand flappers, I have NEVER installed one. I only use Korkys.

Korky flappers are the best. They are the only ones I will use except for some speciality ones that need to be OEM.

Toilets are designed to Fill n Flush, not run. As suggested by others you may have a faulty flapper that is not mating with the flush valve and "venting" A heavy duty food coloring tab will confirm this. You might also have a "nick" on the base of the flush valve or a crack which is allow water to bypass, thus causing the refill value to fill for 5 seconds.

Best Wishes

I even use the Korky "specialty" flappers for those applications. I NEVER purchase OEM flappers.

In addition to those possibilities another one would be the refill tube siphoning the water out, and there could be other possibilities as well. Only by being there could we give a definitive answer.

was it completely rebuilt? or just a flapper replaced

i recommend a complete rebuild...take the tank off replace the flush and fill valve with factory originals

many 'service' plumbers replace flappers, but i dont...i dont want the call back....when it leaks i replace the whole flush valve....not 1 call back this way

The "call back" would be because of HOW you did it, NOT because you replaced the flapper. I replace many flappers EVERY week and do NOT have call backs. IF I rebuild the entire tank everytime, I could not sleep at night knowing I had been "gouging" my customers. But there are MANY plumbers, and companies that do sleep well at night, dreaming about the balance in their checking accounts.
