Customer had a leak in irrigation valve on the mainline tree. The irrigation line is piped in copper. The entire house is piped in CPVC. The house is 20 years old. I would not recommend using the plastic ball valve on the plastic cpvc line. The main shutoff valve works. This is the valve that should be used if the water needs to be shut off. We talked about repiping the whole house in pex to protect the home from future problems with the cpvc. I gave an estimate of 16-19k to repipe the house. It depends on how many fixtures, if any, will be replaced. The price can be narrowed down when they are ready to move forward
