A Shutoff Valve You Can Reach
When there is a leak, being able to turn off the water quickly limits the damage. On this job, a new ball valve was installed in a valve box at the side of the home, so the water can be shut off at the side of the home.
A ball valve is a type of shutoff valve. A quarter turn of the handle opens or closes the flow of water.
Finding a Leak Underneath the Home
Water under a home can come from the water supply lines or from the drain lines, and the repair depends on which. On this job, the leak was at a fitting on the water supply piping.
