How Do I Repair a Leaking Bathroom Faucet?

The first step in fixing a leaking bathroom faucet is to shut off the water supply and close the sink drain. Tape the jaws of the wrench to avoid putting scratches on the fixture. Remove mineral deposits on the faucet parts by using vinegar oil. The necessary tools needed for this task include a flat-head screwdriver, an adjustable wrench, replacement O-rings, washers and penetrating oil, such as CRC.

There are four kinds of faucets. Therefore, it is vital to know what kind of faucet a bathroom has before fixing the problem. Use a wrench to loosen the nut. The stem appears after loosening the packing nut. Depending on the faucet type, the stem twists off from the valve or pops right off.

Inspect the O-ring and washer at this point since they can be the cause of the leaking faucet. If the washer has an issue, remove it and put the replacement on the valve seat. The replacements must be an exact fit. A homeowner can seek the help of a plumber to buy the right size of O-rings and washers for his faucet. After making sure everything is intact, reassemble all the faucet parts accordingly and then turn the knob slowly to see if the problem is resolved.
