Replace water shut off valve under bathroom sink?

  • by

If a shut off valve under a bathroom sink leaks or needs replacing, it is a relatively easy and inexpensive do-it-yourself project. Most modern homes have a shut off valve for each fixture, so the first step is to determine which valve is for the bathroom sink. Once the right valve is located, the next step is to turn off the water to the entire house. This is usually done at the main water shut off valve. With the water off, open the faucet at the sink to release pressure and allow any water in the lines to drain out. With the sink empty, unscrew the handle of the shut off valve so that you can access the valve stem. Next, use a wrench to loosen the packing nut that secures the valve stem in place. With the packing nut loose, the valve stem can be pulled out. The final step is to remove the old washer from the valve seat and replace it with a new one. Once the new washer is in place, screw the packing nut back on, screw the handle back on, and turn the water back on.
