Toilet leaking: tank, supply line or base?

Dry it all, find where the water starts, and close the toilet's valve until it's fixed.

6 steps

Tap a step to watch it again.

Wipe the tank, the supply line, the valve and the floor round the base completely dry with a towel.
Look at the bolts under the tank and the seam where it sits on the bowl. Drops forming there mean the tank is leaking. Beads all over the tank on a humid day are only condensation.
Run a dry tissue along the line from the valve on the wall up to the tank. A wet spot at a nut is the leak.
Flush, then watch the floor round the base. Water seeping out from under it means the seal under the toilet.
Turn the oval handle on the wall clockwise until it stops, then flush to empty the tank. That stops a tank or line leak until it's fixed.
Turn it by hand. Forcing an old valve can crack it.
Water from under the base, a cracked tank or bowl, or a valve that won't close: stop there and ask Handyman for a plumber.

Handyman says: Keep the water off. I'll find a plumber.
