Plumbing valves such as water shut offs can be attached to the water pipe with solder or with a compression fitting. A compression fitting has a small brass ring called a feral that is placed on the end of the pipe after the nut and before the valve. When the nut is tightened to the valve the feral makes for a water tight seal between the two. Installing a compression fitting takes only 10 minutes even for the beginner.
Things You'll Need
- Adjustable wrench
- Channel lock pliers
- Fine grit sandpaper
- Small hacksaw
Shut off the main water valve for the house and remove the valve that is being replaced. A hacksaw may have to be used to cut off the old valve. Make sure it is cut as evenly as possible.
Sand the end of the pipe to make it as smooth as possible to accept the feral for the compression fitting.
Place the nut on the water pipe first with the threads pointing to the end of the pipe.
Push the feral onto the end of the water pipe so that no more than 3/4 of an inch of the end of the pipe extends passed the feral.
Install the new valve and tighten the nut. Do not over tighten the nut. Turn on the water supply. If there is water dripping from the compression fitting tighten the nut a little at a time until the drip stops.
