Hi,

Water is slowly leaking into the bowl from the tank. I replaced the flapper and it did
Not help. I replaced the flush valve and no help there. I had to replace the flush valve
Since I broke it (old style flush valve) while checking it to see if that was the problem.
I replaced the flush valve and no help there. So, now everything in the bowl is new.

There is no water on the floor or anywhere outside.

Water leaks slowly into the bowl and the tank refills every few minutes to replace the
Lost water.

I turned off the water to the toilet bowl before going to bed and checked it next day
Morning. There is no water in the bowl. Zero. Not even a drop. It is completely
Empty.

What could be the problem?

Thanks,
Ram

From what you describ you have 2 separate problems. #1 tank leaking into the bowl- flush valve and flapper are the only connection. If the flapper is sealing then the foam washer under the flapper needs to be tightened. #2 " no water in the bowl" this is unrealted to the tank issue and can happen if your vent stack is clogging and causing siphoning. Or did you mean no water in the tank?

Sorry, I meant the tank, not the bowl.
There is no water in the tank after turning off the water overnight. All of it is emptied.

Okay, your new flapper isn't sealing to the flapper seat, could be incorrect flapper chain adjustment, or a bad seat. Check to make sure flapper is closing completley(chain adjustment will play a factor in this) Also check to make sure flapper seat(area where flapper seals to), is smooth with no noticeable gouges that would allow water to pass.

Try this kit. It is epoxied to old drain seat, so every thing is new.

Yep, these usually work great, as long as you take the time to get the seat very clean and very dry before installing.

Yes, flapper is closing completely. It is new and came with the flush valve, similar to the one suggested by hkstroud.


Thanks everyone. I will try all the suggestions.

If it is the flapper then why did the whole tank become empty? I would think there will be some water left after shut off
Water to the tank.

If the leak was the flapper there should have been about 3/8" of standing water in the tank in the morning. If it was near bone dry check the large foam washer between the tank and the toilet

Your tank can only drain all the water out of the tank and leave it bone dry from three places. The connection between the flush valve and the tank or the two tank bolts. As Bob pointed out if it leaked through the flapper you would have some standing water left. However, if the water drained out through these openings it would drain on to the floor and not, like a flapper leak, drain back into the bowl.
Are you quite sure the tank didn't have some water left? Regards, Tom

How do you replace the foam washer if that's the problem

That's called a "spud washer" (see image) You must remove the tank to replace it, I hope you used a spud wrench (see image) to tighten the flush valve nut. Good luck, Tom
