Phantom Toilet Leak


We have a constant and distinct drip-drip-drip inside the basement waste pipe that hooks directly the first floor master bedroom toilet. No water on the bathroom floor, and no phantom flushes. The shower drain is also hooked to same waste stack, but the drip occurs all day and night long after showers are done. Any ideas what needs fixed? Last plumber that looked at this only replaced the flapper. Thanks!

Phantom Toilet Leak


Hi and welcome to the forum.

Sounds to me like the flapper is still the culprit. Listen VERY carefully with the lid off and see if you hear anything.
Then take a stick and gently push down on the flapper to be sure it's sealing tightly. There might just be some crud under it the plumber missed too....

Could be the tube running from the inlet valve into the overflow tube, I've seen those leaking/dripping before.

Shut off the water to the toilet---See if the water level in the tank changes overnight.
no change--flapper is good. see if the dripping noise has stopped .

Overflow tube discharges into the bowl though, so there shouldn't be a constant drip drip, eh?

If the bowl is full every drop that drips goes down the drain

2 reasons this would cause a problem. Fill valve is leaking slightly enough to allow just the bowl primer to drip, OR, the tube for bowl primer is too long. If it is below the water level in the tank, it will siphon.

Posts like this one really make me itch to go LOOK and see what is happening.
The process of elimination is SO much quicker that way! lol
Here's hoping one of us has the solution.... (oh'mike still has the best idea for troubleshooting it I think.)
I love it when one of us helps solve these problems.... makes me all tingly inside... Po)
