10 Easy Steps on How to Manually Close a Zone Valve
Step 1: Shut Off the Water Supply.
Before you start, turn off the main water valve to your home, which will stop any water flow through the pipes. If the water needs to remain on for other parts of the house, then shut off individual valves for just the zone valve you are working with. Don’t forget to relieve pressure before beginning the job.
Step 2: Drain the Pipes.
Open the lowest faucet in your home, and allow all of the water to drain out of the system. This will ensure that there is no pressure on the zone valve while you are working. Additionally, it will prevent any water from spilling out of the pipe when you open it.
Step 3: Locate the Zone Valve.
Once you have drained the pipes, locate the zone valve you will work on. Be careful when handling the valve, and make sure that it is secure before you begin. Otherwise, the valve can become damaged.
Step 4: Remove the Handle from the Valve.
Using a screwdriver or crescent wrench, remove the handle from the zone valve This should expose a stem that be turned by hand to close off water flow through the valve. Ensure that you save all parts for reassembly later.
Step 5: Unscrew the Valve Stem.
Using a wrench, turn the valve stem counterclockwise until it is loose and can be pulled out of the body of the valve. You can use needle-nose pliers to help grip the stem and pull it out. It will be tight, so you may need to apply some force.
Step 6: Clean Out Any Debris.
Using needle-nose pliers or other tools, remove any debris that may have collected inside the valve. This will ensure that it works properly when you reassemble it. Moreover, it can prevent future problems with the valve.
Step 7: Replace Any Parts Needed.
If any parts need to be replaced, such as O-rings or gaskets, make sure to do so before attempting to close the zone valve again. This will ensure a leak-free seal and smooth operation. Another option is to purchase a new zone valve.
Step 8: Reinstall Handle and Screw in Place.
Put the handle back on the valve, and use a wrench to tighten it in place. Be careful not to over-tighten the handle and damage the valve, as this may cause it to malfunction. Instead, use just enough force to ensure that it is secure.
Step 9: Close Zone Valve.
Using your hands or a wrench, turn the stem clockwise until it is fully closed. If turning is difficult, use a wrench and gently apply pressure. Once the valve is closed, you should not be able to turn it anymore.
Step 10: Test the Valve Once Again.
For safety purposes, open up all of the faucets in your home once again and turn them off one by one to check that all are working properly before turning the water supply back on at the main valve. Remember, the valve should not be able to open when it is shut off.
Once you have followed these steps, your zone valve should be properly closed! You can now enjoy peace of mind knowing that it was done correctly and that you saved yourself both time and money by taking on this project yourself.
