Toilet Tank Leak Issue... Ideas
Posted on 1/19/21 at 11:54 am

So other night heard a ghost fill in the middle of the night. Looked at all the parts in the tank and figured the flapper probably just a bit worn out. (We have been in the house 3 years so do not know the age of everything)
Fast forward the toilet ghost fills again in the night and I start investigating further. It is clear that the tank loses water extremely slowly, like probably takes 5-6 hours for it to drop enough for the fill to occur.
I want to verify that the leak is actually occurring around the flapper again, and I add food coloring. I observe it over 5-6 hours and no food coloring enters the bowl and the tank does not lose any water. However after flushing all the food coloring again from the toilet, I observe it starts losing water again...
Try again this morning,I shut off the water. I noticed that the tank has lost a small amount of water. Only thing I do is add food coloring... stops leaking!! It has been 3 hours and the water level in the tank has not dropped.
Just to verify, there is no water or wetness outside of the toilet on the floor anywhere. Is it safe to assume it is leaking into the bowl or not? I already replaced the flapper, should I try another one? Possibly the gasket?
TL;DR
Toilet tank leaking
Food coloring makes it stop???
Replaced flapper still leaking
Whats next?

Since you already have a new flapper, I'd look at replacing the tank gasket next. I've had one develop a very slow leak there before. The big gasket between the tank and the bowl.

Check the overflow tube for cracks.

Happened to one of mine a few years ago. Pretty simple fix, but if you're taking it apart to fix that, might as well go with a new column as well. Parts are super cheap, and they're very simple to repair.

check your overflow and fill valve...
had similar issue...had a slow dribble of water into toilet.. changed flapper then tank seal...
still had a slow dribble into toilet base...
looked at the fluidmaster fill valve and saw a dribble coming out from top...was not shutting tight...this slow dribble filled the tank high and would cause it to spill into the overflow and then into toliet...(changed fluidmaster again..was not old ..)
another toilet doing similar thing but different reason...had the shutoff height of fluidmaster set at same height of overflow tube...reset the fluidmaster shut off lower than overflow tube by an inche more and stopped (actually original setting was done by plumber when had a new toilet put in )

This will do it! I fixed one a couple of months ago that was trickling into the overflow tube. Adjusted the float down 1/2 inch or so and fixed the problem.

I have five toilets that and it seems like one is always in need of something.
One thing I've learned is just save the time and aggravation of throwing random parts and do a complete rebuild.
Also, there's a repair kit out there (couldn't find to link) at Lowe's or HD that will prevent the tank from refilling if the water leaks out slowly. I've used it on a few toilets that aren't used often (basement, bonus room). It'll save your water bill.

Thanks for all the replies, something so simple can be so aggravating.
Long story short, I finally got it to leak consistently and left it over night. It drained all the way down to just below the flapper seal. I check the seat and it does not look rough or pitted, but somehow water is passing through it.
Going to try one of those seat repair kits. Otherwise next step is replacing everything including disassembling the gasket etc..

Dang, thats a lot of water to be leaking.
I sanded my seat with wet dry sandpaper and it stopped the ghost flushing. Good luck and keep us posted.
