Over time, the joints between pipes—especially PVC, stainless steel, or copper—can loosen, corrode, or crack, allowing water to seep through the connection points.
types of leaking sink/basin
Under-Sink Drain Pipe Leaks
Leaks under the sink are often caused by loose connections, worn washers, or corrosion in the drain pipes. If left unaddressed, they can cause water damage to cabinets and flooring.
Flexible Hose Leakage
Flexible hoses connecting taps to water supply lines can develop leaks from wear, poor installation, or loose fittings. Replacing or tightening hoses prevents drips and water wastage.
Bottle Trap or P-Trap Replacement
The U-shaped or bottle-shaped trap beneath your sink may crack, corrode, or develop worn seals. Replacing or repairing it ensures proper drainage and prevents leaks.
Loose Basin Tap and Valve Leaks
Basin taps and valves can leak at the base or spout due to loose fittings, worn washers, or corroded components. Proper repair or replacement ensures smooth operation and stops water loss.
Cracked PVC or Copper Waste Pipe Repair
Waste pipes can crack due to age, physical damage, or water pressure fluctuations. Timely repairs prevent water damage, foul odors, and plumbing failures.
Basin Overflow or Drainage System Issues
Overflow leaks or clogged drainage systems can cause water to back up, creating pooling or spillage around the basin. Clearing blockages and fixing overflow components restores proper drainage.
Detecting Concealed Sink / Basin Pipe Leaks
Not all sink pipe leaks are obvious. Water might drip slowly behind a cabinet, soak the floor from beneath, or leak into walls. To catch and fix these leaks early, we use modern diagnostic tools:
- Thermal Imaging Cameras – Detect hot water leaks inside walls
- Moisture Meters – Find dampness under tiles or flooring
- Dye Tracer Tests – Identify leaks in drainage or trap systems
- Acoustic Listening Devices – Locate leaks inside walls or concealed pipe runs
