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

A toilet leaking at the base when you flush usually means the wax ring failed or the closet bolts are loose. Other causes include a cracked flange or bowl, misalignment after prior work, or a severe drain clog pushing past the seal. Stop using the toilet to avoid subfloor damage. We service Englewood and Clifton.

• Gently rock the toilet; movement suggests loose bolts or a flange issue.
• Tighten bolt caps a quarter turn. If it still leaks, shut off water and call.
