Fix a Leaking Toilet
A leaking toilet can waste a lot of water and cause damage fast. Here’s a practical checklist to help you find the cause and fix it safely.
1) Identify where the leak is coming from
Most toilet leaks come from one of three places: the tank-to-bowl connection, the supply line/shutoff valve, or the base (wax ring). Dry the area, then watch for fresh water to pinpoint the source.

2) Fix common leak points
Supply line/shutoff valve: tighten the nut slightly; replace the supply line if it’s corroded or dripping.
Tank bolts/gasket: if water appears under the tank, replace the tank-to-bowl gasket and bolt washers.
Base leak (wax ring): if water seeps from the base after flushing, the toilet likely needs to be lifted and the wax ring replaced.
When to call a pro
If the toilet rocks, the floor is damaged, or you suspect a cracked tank/bowl, it’s best to hire a licensed plumber.
