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

A toilet leaking at the base when you flush is most often a failed wax ring seal. Loose or corroded closet bolts, a damaged or misaligned flange, or hairline cracks can also cause base leaks. We handle seal and flange replacement, tighten or replace bolts, and verify proper flushing and drainage with flat-rate pricing. Our Tucson-area team uses advanced leak detection to pinpoint issues and prevent repeat leaks.

Quick checks:

• Stop use and shut off water.
• Gently test bolt caps for looseness.
• Wipe dry, flush once, and look for water at the base.
