Leak under a sink or basin in Aberdare and the Cynon Valley
A drip inside the cupboard traced and stopped — a waste connection, a trap seal, a tap tail or a flexible hose.
How you know you need it
A damp patch at the back of the cupboard, a bucket that has become permanent, or the chipboard base starting to swell.
Why people put it off
A bucket works. Until the cupboard floor goes soft and the job becomes a joinery job as well as a plumbing one.
What is involved
Finding which of the four or five joints under there is actually leaking, and replacing the failed part rather than the whole assembly.
