Replace Top Entry Ball Valve 2012-04-18

Top Entry Ball Valve and the more cheaply made gate valves are designed to shut off the water supply to a location, such as an irrigation system, or a device, like a water heater or sink. Most in-line valves inside a home are typically gate valves, but they may rust out quicker. So, if you need to change a defective gate valve, go with the more durable ball valve. The ball valve consists of a handle on a shaft attached to a metal ball with a hole in it. When the handle is turned in the water flow direction, the hole is covered up, preventing the flow of water through the valve.

1 Shut off the water supply. Once the water supply has been turned off, turn on a valve or faucet in order to relieve any water pressure in the line.

2 Determine which type of pipe supplies you will need. If the valve is in PVC pipe you will need PVC pipe cleaner and cement. If the valve is in copper piping you will need to sweat the pipe joints and Forged Steel Ball Valve into place.

3 Remove the old valve from the pipe. Using the hacksaw, cut the pipe on each side of the valve. You do not need to cut it especially close to the valve since you will be splicing the pipe.

4 Splice a section of new pipe into the opening. Measure the opening, making certain to allow for the width of the new valve. Cut a section of pipe and secure it in place on one end with the pipe coupler fitting.

5 Secure the new ball valve in place. The type of pipe in use will determine what process you will need to use to secure the valve. Turn the water supply back on and test for leaks.
