Replacing hot water shut off valve under kitchen sink.

My water supply valve under the kitchen sink leaks. 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. Open the cabinet below the sink and remove anything stored there. These inexpensive little valves rarely get used and when they do sometimes they leak.

The hot and cold water supply under the sink is turned off at the valves. Start with the kitchen sink shutoff valve turn the taps to the off position. I am replacing the faucet in my kitchen. The cold water supply line from the wall is dripping water slowly.

Put a bucket under the drain pipe. Turn off the main water supply for the house. I have the faucet installed in the sink but not connected to the hot and cold water.
