Did you winterize the inlet valve........disconnect water line from valve then operate it to get water out of valve
OR pump anti-freeze thru the valve?


Sounds like inlet valve is leaking .......time to replace

Replaced the valve today. Will watch and wait to see if this solved the problem.

Thanks you all for the advise.

Do you have to winterize that toilet in the winter? Wondering if freezing water could be the culprit? Hard to get the water out of those valves.

Vacuum breakers are usually the culprit when it comes to intermittent leaks.

They have a small hole in top that gets plugged by a flapper when water flows from inlet valve to bowl. Then when water flow stops flapped drops allowing air in and water drains into bowl.

If flapper is worn out water can spurt out small hole before flapper closes it.

Vacuum breaker is at top of backside of toilet

Use the water pump instead of city water. You will know when it is leaking if the pump cycles on and off.

Sit on it, have someone else look for leaks while you are sitting on top of it. Sit on it, then remove yourself from sitting on it, all the while with someone else looking for leaks as you do so.

ID WHERE the leak is...then you can fix it.
Need to remove shroud and test/ID leak

Wrap TP around fittings on water supply line
Wrap TP on water valve assembly
Wrap/lay TP on/under vacuum breaker

Then which wad of TP gets wet is the leaker

Could be bowl band is loose

Tried that plus paper on floor to isolate drips,etc with no luck. Today there has been no leak!
