Leak Under The Sink

A leak under the faucet can be the hardest to notice for the obvious reason that most people don’t check for leaks under their faucet very often. If you suspect a leak under the sink it is a good idea to locate it and repair it right away before the water damages the vanity, wall, or even the bathroom floor. Start by taking everything out from under the sink and thoroughly drying everything off. Now you can run a bit of water to see where it is leaking from. Sometimes a faucet will have to be turned on all the way before it will leak and check both with hot and cold sides on. The leak can be very small so if you suspect one but can find it try leaving some dry paper towel all around the base of the vanity for a day or so and then check for water marks on the paper towels.

If the faucet leaks from underneath and you can verify that it is not the flex lines or the drain line leaking it could be a sign that you will need a new faucet. Changing the cartridge or the faucet stem can sometimes remedy the leak from underneath if you want to try to repair it. A faucet repair is less expensive and less time consuming, so if you like your faucet then you can try to repair it before you go through the process of replacing it.

Note: For a newer faucet that is leaking from any of these areas the first thing to do is to check the warranty and contact the manufacturer. Many manufacturers have lifetime warranties on faucet leaks. They can send you the parts you will need to repair your faucet or if it is a faulty faucet they may even send you a new faucet.
