The most common causes of a dripping faucet

-A worn out washer: Over time, washers can become worn out and no longer provide a tight seal. This can cause water to leak past the washer and drip from the faucet.

-An incorrect installation: If a faucet is not installed correctly, it may not be properly sealed and water can escape and drip from the faucet.

– Loose parts: If any of the parts on a faucet are loose, they may not be sealing properly and water can escape and drip from the faucet.

-Calcium buildup: Calcium buildup can cause the internal parts to not fully close, allowing water to pass through.

How to fix a dripping faucet

There are a few different reasons why faucets drip, but the most common cause is a worn out washer. Washers are made of rubber or synthetic materials, and over time they can get hard and brittle. When this happens, they can’t seal properly and water will leak past them.

If you have a dripping faucet, the first thing you should do is check the washer. If it looks worn out, replace it with a new one. You can buy washers at any hardware store.

If the washer is not the problem, then the next step is to check the O-ring. The O-ring is a small rubber ring that seals the connection between the valve seat and the spout. If this O-ring is damaged or missing, water will leak from the spout.

To check the O-ring, remove the handle from your faucet and look for the small rubber ring under the metal plate. If it’s damaged or missing, you can buy a replacement at any hardware store.

Once you’ve replaced the washer or O-ring, reassemble your faucet and turn on the water to test it. If your faucet is still leaking, you may need to replace the valve seat or the entire faucet.
