How to Replace a Ball Valve

A ball valve is a very reliable piece of equipment but when a problem does develop and changing the valve becomes necessary. The procedure for ball valve change is very straight forward, although there can be a great many variables involved that you should be aware of.

Things You'll Need

• Hacksaw
• Replace valve
• Small section of pipe
• Pipe coupler
• Method to secure pipes (depending on the type of pipe involved)
• Tape measure

Instructions

How to Replace a Ball 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 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.

Tips & Warnings

• Once you turn the water supply on allow the water to run for a short period in order to bleed out any air which may have accumulated in the lines.

• If you are sweating copper pipes, be certain to have a proper fire extinguisher close at hand.
