What causes a toilet to leak from the base when flushing?

A toilet leaking from the base when you flush usually means the base seal has failed. A loose toilet can also break the seal and let water escape during a flush. If the bowl is cracked around the seal area, the toilet may need full replacement. Technicians lift the toilet, replace the seal, and secure the base to stop leaks. This is common in homes around Peru, Logansport, and Wabash.

Quick checks:

• Dry the supply line; confirm the drip is only at the base when flushing.
• Gently rock the toilet; movement suggests loose mounting.
