How To Fix Your Leaking Sink

 Posted Friday, March 24, 2017.

It's never fun when you realize that your sink is leaking. Most of the time homeowners will only realize the issue when they notice that, while doing dishes, there is suddenly a large puddle on the floor. Luckily fixing sinks is much easier than fixing a toilet or shower drain. After turning the water off, mopping up any standing water and removing all the items from under the sink, here's what you need to do to fix your sink:

Fixing a Water Supply Leak

  • First locate the shut off valve and the accompanying compression fitting. Most of the time, it's the compression fittings that have become loosened over time.
  • Using two different adjustable wrenches, hold the shut off valve with one while using the other adjustable to tighten the compression fitting.
  • Next check your faucet connection to see if there is a leak coming from there. If so, you will need locking pliers instead to get into the small space behind the sink.

    Fixing a Drain Leak
  • P-traps are usually the culprit of drain leaks due to a loose connection, blockage or corrosion (for metal pipes).
  • First, try tightening any of the screws attached to the P-trap using an adjustable. Run the faucet again to see whether this solves the issue.
  • If there is still a leak, turn the water off and remove the entire fixture and give is a thorough cleaning with warm water and mild detergent. While this soaks, clean the drain to ensure nothing is stuck or blocking it.
  • After re-attaching the P-trap, run the water again to test. If there is still a leak, you will need to replace the part by heading to your local hardware or home improvement store.

    Fixing Other Leaks
  • Other common leaks are usually the sink drain which, after time, can become detached from the basin.
  • First, unscrew the sink drain from the basin and use plumber putty to re-secure the sink drain. Be sure to let the putty sit for at least an hour before using the sink again.
  • Sometimes water can flow behind the faucet and pool under the sink without you seeing any visible signs of leaks or pooling water. In this case, the issue is a bit more serious and we recommend you contact a professional plumber as this will require extensive disassembly and further diagnosis.

If you're having an issue with your plumbing, it's important to get it fixed as soon as possible in order to prevent further damage to your home as well as pay more for utilities due to leaking parts.
