Why does toilet tank leak only when flushed?
The only-when-flushed toilet leak could be caused by loose mounting bolts or a worn-out wax gasket while the all-the-time leak could be caused by a loose water supply line connection, a problematic water shutoff valve, or a faulty seal between the toilet tank and its base.
Why is water leaking from my flush tank?
The most common cause of a leaking toilet tank is when the flapper fails to seat properly and form a tight seal against the valve seat. This lets water leak from the tank into the bowl. It may be caused by the flapper being out of position.

How do you know if your toilet flush valve is bad?
You can spot a faulty fill valve by listening closely to strange sounds that might be coming from your toilet. The sound of water constantly running through the tank can indicate fill valve problems.

When should a flush valve be replaced?
The flush valve assembly also includes the flapper, which seals the opening and holds water in the tank until a flush is initiated. The clearest sign that a flush valve needs to be replaced is when water continues to run, even after the flapper and other possible causes have been addressed.
How tight should a toilet tank be?
Bolts Don’t Have to Be Extremely Tight In some cases, hand-tightening and a quarter-turn is all you need. It’s important to keep in mind that the toilet tank is not intended to take weight and strain. The tank-to-bowl bolts are merely there to ensure the rubber seal between the tank and bowl is snug and leakproof.
Can you tighten a toilet too much?
If you tighten it too much, you can pull the closet bolt out through the flange, ruining the flange or breaking the porcelain. DO NOT tighten it as tight as it will go, like you’re building something or working on your car – you’ll break the flange, chip or crack the porcelain or both.
