How to Replace a Sink Washer
Modern faucets are designed as ball, disc, cartridge and compression units. (Consult the second resource below to determine the type of the faucet in need of repair). Ball-type faucets include a cam washer that over time may become brittle and break. Faucet specifications vary from company to company, so it is important to make a note of any maker identification information located on the faucet. If a maker's name or model numbers are not imprinted on the unit, take a photo of the faucet and bring it to the plumbing shop. Knowledgeable salespeople will be able to quickly assist in identifying the maker. Does this Spark an idea?

How to Replace a Sink Washer
-
1
Turn off the water by tightening both the hot and cold water supply handles under the sink. If these are not present, the main water line will need to be shut off. This is usually located outside the home, or in a cement box near the street, although some older homes have the main shut-off located in a basement or crawl space. Consult the link in the resource section for directions to shut off the main water line.

2
Unscrew the handle ring to expose the cap of the faucet. Place a small towel over the cap, and use the pliers to unscrew the upper part of the unit. If the screw cap has a calcium buildup or is difficult to move, put a small amount of WD-40 oil on the junction where the screw cap meets the main faucet, and try again.
