Toilet leak question...

Have you replaced ALL the innards? The entire flush valve (which requires removing the tank from the bowl)? Have you tightened the bolts that connect the tank to the bowl?

I don’t know the vaseline trick, so I can’t speak to that.

yup! got all of it replaced, took the tank off and replaced that part as well. all bolts (even the bolts holding it to the floor) were tightened by dad. apparently the vaseline trick is to put vaseline on the flap to help it seal properly to troubleshoot if it’s the issue.

Pretty hard to diagnose without seeing it. Sometimes a toilet gets hairline cracks in the porcelain that are nearly invisible—and impossible to repair.

I had this same sort of problem a few years ago when I installed a very good, but used toilet in my basement. I completely rebuilt the toilet and after installing it, the tank was always running water in to the bowl continuously. After many, many attempts to solve the issue, I found the the flush valve mechanism had a defect that was very hard to spot.

One trick you can try is to put food coloring into the tank after it’s full, the leak will pull the coloring to where it’s going out.

Usually but not always, it is the flapper and flapper seal. If it leaked for a bit (a few days), run your finger nail around the seal that the flapper sits on. What happens is the sealing edge gets a crack or a small erosion groove across the seal edge and at that point, it well never seal. The only remedy is to replace the flapper and seal fitting with new.

As dbray45 has correctly pointed out, a continuous leak of water into the tiolet bowl STARTS at the flapper valve lip. Replacing the innards from cheap supply houses (Lowe’s, etc) often doesn’t solve the problem as much of their supply is cheaply made offshore / elsewhere. The flapper lip and seat often have very small ridges, tears and cracks in them that cause continued leaking – despite being brand new. Do a thorough check of both the seat and the lip on the flapper valve to ensure this is isn’t the problem.
