You don’t have to panic if you discover that your kitchen sink is leaking underneath, and you don’t have to contact a Santa Cruz plumber immediately. Everything you need to know about fixing a leak beneath the sink is provided here!

Kitchen sink leaking underneath

The most frequent cause of water under your sink is a drain leak. Plumbing pipes under your sink may gradually and regularly leak water that runs down the drain due to shifted plumbing lines, corroded pipe connections, or wear and tear.

How to Stop Leaking Sink

Tighten the pipe slip nuts to begin repairs, starting with the one closest to the sink. Use silicone tape or epoxy putty to seal the area around the slide nuts if the pipe leaks even after that. Rubber gaskets in the pipe may need to be replaced if the leak persists.

Determine Where the Sink is Leaking

The first step in fixing your kitchen sink is to locate the leak. Depending on where the leak is, there may be many various ways that your kitchen sink may be addressed. To find the source of the leak, do the following actions.

Check If The Drain Leaks

After filling your sink with water, drain it. This kind of leak occurs when water is seen seeping from the sink as it drains. The cause of the leak in your kitchen sink will determine how to repair it. Attempt to ascertain if there is a blockage, corrosion, or merely a loose object. Just tightening the bolts at the intersection of the pipes will solve the issue. If not, the plumber’s putty may be used to finish the task. The drain may be removed, replaced with a new plumber’s putty, and put back in place.

Check If The Faucet Leaks

Although they might be inconvenient and increase water costs, leaky faucets are usually the simplest to find. Every time someone turns on the faucet, you can observe water dripping from the top of the sink. Make careful to examine under your kitchen sink for leaks since faucet leaks may also occur there. All you have to do to repair it is swap out worn-out gaskets or failing washers. Sometimes, you must replace the whole faucet because of a significant leak. Although changing your kitchen faucet is not too difficult, if you find it uncomfortable, have one of our local plumbers install your sink instead.

Check The Water Supply Leaks

You may not be aware of a leak in your water supply until it starts to pour out of your ceiling, creating a significant mess and perhaps water damage! Plug the drain on your sink, turn on the water, and let it run to see whether the source of your leak is your water supply. Your water supply leaks if there’s a leak under the kitchen sink while the water is flowing but not draining. Try to locate the pipe or junction where the water is escaping and tighten it. If that doesn’t stop the leak, you may need to replace the connector’s corroded or failing gasket.

Inspect For A Clogged P-Trap

The bent portion of a pipe under the sink is called a P-trap. Since the P-trap is hidden, you may immediately detect a leak. Its primary function is to stop foul odors from escaping down the drains, but it may also catch food particles and debris. A leak may occur at the P-Trap if debris builds up.

Check For A Corroded P-Trap

Corrosion is another potential reason for a leaky P-trap, particularly if your sink has metal components. Should this be the case, you could have to get a new trap altogether. If you’re uncomfortable replacing the P-Trap or locating a substitute trap, contact a nearby professional for plumbing repairs.

Look For A Damaged O-Ring

A screw holds the faucet handle in place, and an O-ring—a small linked disc—is one of the countless components that comprise your kitchen sink. Regular use may wear out or loosen the O-ring, resulting in a leak around the faucet’s handle. If the O-ring is damaged, just replacing it should resolve the problem.

Check For A Worn Washer

One of the most prevalent reasons for sink leaks is worn washers. The washers wear out because they are forced on the valve seat every time the faucet is used. Leaks surrounding the spout may become apparent if your washers are worn out. I just swapped out the washer.

See If You Have Valve Seat Corrosion

The valve seat is the fitting that links the spout to the faucet’s body. Water that gathers around the valve seat may corrode and cause a leak near the spout. Regular cleaning of the valve seat is recommended, or you may pay a plumber.
