Water leaking from under bathroom sink cabinet in Quebec City - source mystery

Jack Thompson · · 3 replies

I noticed some water damage and a slight puddle forming under my bathroom sink cabinet in Quebec City. Not sure if it’s a leak from the faucet, drain pipe, or just condensation. The cabinet is about 10 years old and has had some humidity issues. How do I best diagnose without tearing everything apart? Any advice on cheap leak detection or moisture meters available locally?

Try using food coloring in the sink basin and watch the pipes for drips after a flush.

You can buy a simple moisture meter at Canadian Tire for under $50, helped me locate hidden leaks.

Check all rubber gaskets and connections under the sink—often replacing a faulty seal solves the problem.
