Kitchen Faucet Leaking Under Sink and How to Fix It

Most of these leaks can be solved with the simple tightening of compression fittings around the shutoff valves. Grab a wrench to tighten the valve and use your hands to tighten the compression nut. While this tightening should fix your problem 90% of the time, sometimes your sink will leak directly underneath the tap itself. In order to reach these valves and tighten them up, get some adjustable pliers and get to work.

Check the Drainage Pipe

If you notice leaking only when the sink is full of water, your problem is most likely with the drain itself. You will need to shut off all the water and take apart the drainage pipe, remove it clean it and replace it ensuring that everything connected to it is sealed tightly. Use some plumbing putty to pack around the connections and valves to prevent any water from leaking through. If this does not work, you may even need to get a new drain seal to stop the leaking in the sink.

After you attempt to fix any plumbing problem, you should always try to see if the leak returns. The last thing you want to see is all your time and effort go to waste as you discover your sink is leaking once more.

If you still find that you have a leaking problem after trying to fix your leaking sink, you will need to contact a professional. A plumber may just be the answer to your faucet fixing problems.
