Blocked sink, bath or shower in Aberdare and the Cynon Valley
A slow or blocked waste cleared, and the trap cleaned out properly rather than chemically masked.
How you know you need it
Water standing in the basin, a gurgle from the overflow, or a smell that comes back a day after you pour something down it.
Why people put it off
Supermarket drain unblocker is cheap and sometimes works, so it gets bought four times before anyone phones a plumber.
What is involved
Clearing the trap and the waste run, and checking why it blocked — a trap that keeps filling is often a fall problem rather than a debris problem.
