WATER UNDER THE KITCHEN SINK AGAIN? THE TAP IS RARELY THE PROBLEM - THE WASTE AND TRAP USUALLY ARE
Recently completed in an office building in Mauritius: a leaking kitchen sink on one floor and a clogged sewerage pipe serving the toilets on another. Two of the most common plumbing calls we get, and two jobs where the quick fix rarely lasts.
WHY SINKS LEAK UNDERNEATH
- Old waste fittings: the plastic nut and washer under the bowl harden and crack with age and hot water.
- Mismatched parts: a trap patched together from different sizes and sealed with tape or silicone.
- No support: a loose waste pipe gets knocked every time the cupboard is used, and the joints open.
WHAT FAILS
Silicone or tape around a dripping joint. It holds for a week, then the water finds its way out again - straight into the cupboard base, which swells and rots long before anyone notices.
THE LASTING FIX - WHAT WE DID
1. Traced the leak to the sink waste and trap connection.
2. Removed the old fittings and fitted a new waste outlet, PVC trap and elbow, correctly sized and aligned.
3. Tested under full flow with the tap running - no drip at any joint (see the video).
4. On the other floor: cleared the clogged sewerage pipe serving the toilets and restored normal flow.
A slow drip under a sink or a toilet that keeps blocking is not just an inconvenience in an office - it damages joinery, floors and the ceiling of the floor below.
