Plumbing – Toilet drainage leak

drainleakplumbingtoilet

We have a problem with our toilet. When we flush it, water rises in the bowl, then slowly leaks away through the drain onto the floor. I took a video of the problem to possibly send to a plumber. However, firstly I wanted to know if it is possible to fix it ourselves.

The water seems to be leaking through cracks in the caulk where the drainage pipe goes into the floor. I was wondering if unclogging the toilet and re-applying the foam/paste would solve the problem, or if it would only serve as a temporary fix. We haven't tried this yet because:

  1. We currently don't have a plunger.

  2. We don't want to worsen the problem in case a plumber needs to come

All help is welcome and thanks in advance!

That is not at all how a toilet should connect to the floor. You'll need to remove the toilet, clean away all the caulk, and set it anew.

In my part of the world we use a ring of waxy material, sometimes with an embedded rubber flange, to make the seal between the toilet and the floor. This is a one-time use product and must be replaced if the toilet is re-set.

Anytime you encounter caulk in plumbing you can assume that something is very wrong. If it hasn't failed already, it soon will.
