My Bathroom Faucet Is Leaking Under The Sink

A leaking faucet is a common household problem that can waste a lot of water and increase your utility bills. If you have a bathroom faucet that is leaking under the sink, there are a few things you can do to fix it yourself.

First, you need to identify the source of the leak. To do this, turn on the faucet and look for any water dripping from the base of the faucet, the connections to the water supply lines, or the drain. Once you have found the source of the leak, you can begin to repair it.

Faucet Base Leak

If the leak is coming from the base of the faucet, it is likely caused by a worn-out washer. To fix this, you will need to replace the washer. To do this, first, turn off the water supply to the faucet and open the faucet to release any remaining water. Then, use a wrench to loosen the packing nut at the base of the faucet. Once the packing nut is loose, you can remove the faucet handle and the stem. The washer is located on the end of the stem. Remove the old washer and replace it with a new one. Reassemble the faucet and turn on the water supply to check for leaks.

Water Supply Line Leak

If the leak is coming from the connections to the water supply lines, it is likely caused by a loose or damaged connection. To fix this, you will need to tighten the connection or replace the damaged part. To do this, first, turn off the water supply to the faucet and open the faucet to release any remaining water. Then, use a wrench to tighten the connection between the water supply line and the faucet. If the connection is damaged, you will need to replace the damaged part. To do this, cut the damaged section of the water supply line and insert a new section of pipe. Use a wrench to tighten the connections between the new section of pipe and the faucet and the water supply line.

Drain Leak

If the leak is coming from the drain, it is likely caused by a worn-out or damaged washer or gasket. To fix this, you will need to replace the washer or gasket. To do this, first, turn off the water supply to the faucet and open the faucet to release any remaining water. Then, use a wrench to loosen the drain nut. Once the drain nut is loose, you can remove the drain assembly. The washer or gasket is located on the bottom of the drain assembly. Remove the old washer or gasket and replace it with a new one. Reassemble the drain assembly and tighten the drain nut. Turn on the water supply and check for leaks.

Tips for Preventing Faucet Leaks

Second, replace the washers and gaskets on your faucet every few years. Finally, do not overtighten the connections on your faucet, as this can damage the parts.

By following these tips, you can keep your bathroom faucet from leaking and save yourself money on your water bill.
