Types of Kitchen Sink Leaks

The first step toward fixing your kitchen sink leak is to find it. There are three types of leaks:

How you fix this kitchen sink leak depends on why it is leaking. Try to determine if you have a blockage or if there is corrosion or if something is just loose.
  • Water Supply Leaks. Plug up your sink’s drain, then turn the water on and let it run. If there’s a leak under the kitchen sink while the water is running but not draining, then the leak is in your water supply. See if you can find the joint or pipe where the water is getting out.
  • Other Leaks. You may have a leaky faucet that is dripping water down under your sink. The leak may also be in one of the traps under your sink. Keep looking until you determine what is leaking.
