Water Leak From a Faucet, Sink or Pipe: Causes and Repair

From $117.76 fixed price4.9 from 136 Google reviewsSame-day slots

A dripping faucet, a puddle under the sink or a damp patch around a pipe joint usually has a simple cause: a worn part inside the faucet, a loose or corroded flexible hose, or a failed seal at a joint. Left alone, even a slow drip wastes water, stains basins and can rot the cabinet under the sink.

What to Do Right Now

  1. 1Turn off the water. Use the small isolation valve on the pipe under the sink or basin. If there is none, or the leak is on a pipe, close the main water valve, usually next to your water meter.
  2. 2Protect the area. Dry the floor and cabinet, and put a bowl or towel under the drip so you can see how fast it leaks.
  3. 3Find the source. Dry everything with a cloth, turn the water back on briefly and watch: the spout (worn cartridge or washer), the base of the faucet, the flexible hoses, the trap under the sink or a pipe joint.
  4. 4Check the easy fixes. A flexible hose connection that has worked loose can be tightened gently by hand. Do not over-tighten, as that cracks fittings.
  5. 5Take a photo of the leak and the parts around it. It helps the plumber bring the right parts.

Stop and call a plumber if

  • Water is coming from inside a wall, from the floor tiles or from the ceiling
  • A pipe has burst or is spraying
  • Water is near a power socket, switch or appliance
  • The leak continues with the valve closed

Common causes of faucet, sink and pipe leaks

  • A worn cartridge or washer inside the faucet, which causes a steady drip from the spout
  • A loose, kinked or corroded flexible hose under the sink or basin
  • A failed seal where the sink meets the waste pipe or bottle trap
  • A cracked or corroded joint on an exposed copper or uPVC pipe
  • High water pressure wearing out seals faster than usual

What Affects the Price

  • Whether the faucet can be repaired or needs replacing
  • Faucet and hose leaks versus a leak on the pipe itself

Faucet, Sink & Pipe Leak Repair FAQs

StringsSG fixes water leaks from faucets, sinks and pipes from $117.76 at a fixed price. Replacing the faucet, a flexible hose or repairing an exposed pipe each have their own price in the table on this page, and you see the total before you confirm.
Leaks under a sink usually come from a loose or worn flexible hose, the seal where the sink joins the waste pipe, or the bottle trap. Dry everything, run the tap and watch each joint to see which one drips first.
Yes. A constant drip adds up to a lot of wasted water over a month, shows up on your water bill, and the worn part usually gets worse over time. It is normally a quick repair.
A ceiling leak often comes from the unit above rather than your own pipes. In an HDB flat, contact your HDB Branch to investigate inter-floor leakage. If the leak is from your own exposed pipes, a plumber can repair it.
