Is your kitchen sink leaking? This is a frustratingly common occurrence that many homeowners experience at least once in their lifetimes. When you find a leak under your kitchen sink, though, you don’t need to worry, and you don’t need to call a Santa Cruz plumber right away. Here’s what you need to know about how to fix a leak under the sink!

Types of Kitchen Sink Leaks

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

  • Drain Leaks. Run water into your sink, then drain it out. If you see water leaking while the sink is draining, then you have this type of leak. 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.
