Leaking Kitchen Sink Trap? How to Stop It Before It Damages Your Kitchen Cupboard
A leaking kitchen sink trap might start as a slow drip, but if left untreated it can soak and damage your cupboard, create bad smells, and even cause mould growth. At Afterglow Plumbing & Heating, we’re an emergency plumber in Birmingham who has repaired countless sink leaks — often saving customers from costly kitchen replacements.
Why Your Kitchen Sink Trap Might Be Leaking
There are several common reasons a sink trap can start leaking:
- Broken Waste Screw – Sometimes the problem is in the waste fitting itself, where the screw has snapped or corroded.
- Perished O-Rings or Rubber Washers – Seals can dry out, harden, and stop forming a watertight joint.
- Over-Tightened or Cracked Nuts – Plastic fittings can split if they’re tightened too much.
- Misaligned Pipework – Even a small shift can break the seal.
If you spot a drip, it’s important to act quickly. What starts as a minor leak can soak into cupboards, flooring, and walls, leading to swelling, stains, and expensive repairs.
When to Fix a Leaking Sink Trap
- Immediately – Small leaks can quickly turn into constant drips.
- Before Mould Appears – Moisture trapped in cupboards can lead to mould and mildew.
- Before Cupboard Damage – Chipboard swells when wet and often can’t be repaired.
