How to Turn Off a Water Shutoff Valve
Installing a water shut off valve is an important step in any plumbing project. If you are looking for help with this installation, check out the steps below. Remember to work safely and be prepared when doing so.
First, you will need to shut off your home’s main water supply by turning the lever on top of the meter until it is perpendicular to its pipe or house connection; then turn the handle clockwise three times (or more) to lock it into place
Then you should turn on all faucets and sprinkler heads before shutting down your home’s main water supply
And finally turn the water supply back on to make sure that it is working properly.
In this example, we will use a quarter turn shut off valve.
You’ll want to measure the distance between where you are placing your water supply and your house connection; then add two inches for overlap
Then, determine how far from the edge of the meter box or pipe that you need to place this valve by measuring out what ever length is left after adding in those two inches
Use PVC cement and glue (or silicone caulking) on one side of the inside fitting at this point on the pipe coming into your home’s main line before installing it with screws onto this fitting so that it can’t be removed easily without damaging itself. Then apply both PVC cement and glue all around the outside circumference here as well.
Then you should carefully insulate in any areas where there will be pressure-related contact with the pipe by wrapping it with a layer of electrical tape.
Next, drill into your meter box or pipe and install the threaded end of this fitting using an appropriate washer before screwing on the other side to complete installation.
If you have frozen pipes that need to be thawed out (or shut off), place one hose over another at least three feet long that is connected to water supply from inside house then turn on cold water full blast for 45 minutes so as not to freeze up again due to expansion when freezing temperatures return; do NOT let anyone use running water during this time period either.
