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

A toilet leaking from the base when you flush usually means the wax ring seal has failed or the floor bolts are loose. Water escapes at the base during a flush because the seal isn’t tight. If the toilet rocks or isn’t secured to the floor, leaks are more likely. These are common toilet base problems we repair in Elkhart, Mishawaka, and Granger.

Quick checks:

• Gently see if the toilet wobbles.
• Watch for water pooling at the base after a flush.
• Avoid overtightening bolts; call a pro.
