Replacing Hot Water Shut Off Valve Under Kitchen Sink

Turn off the main water supply for the house.

Replacing hot water shut off valve under kitchen sink.

There are two basic types straight stops and angle stops and these valves normally remain on and are seldom closed functioning maintenance free for years. The water to a kitchen or bathroom sink is supplied through small copper or flexible neoprene tubes from a small control valve called a stop or shut off valve under the sink. The hot and cold water supply under the sink is turned off at the valves. The cold water supply line from the wall is dripping water slowly.

I have the faucet installed in the sink but not connected to the hot and cold water. I am replacing the faucet in my kitchen. These inexpensive little valves rarely get used and when they do sometimes they leak. You should see a large pipe usually made of pvc that has a vertical bend in it before running horizontally to the back wall or rarely down to the floor.

Under sink shutoff valves also called fixture shutoffs or stop valves allow you to turn off the water to the sink or other fixture without having to use the home s main shutoff. Open the cabinet below the sink and remove anything stored there. If this happens to you you can simply replace the valve with a new valve that matches the old one.
