Shut down water to home at meter. Existing main shut off for home in basement area is post pressure reducing valve. Drain down potable water system and cut out main gate valve and three-quarter inch PRV. Replace in proper order with new three-quarter inch pro press ball valve before pressure reducing valve. Install Moen flow three-quarter inch on system as well. Pressurize system slowly and test for leaks. Chen plumbing is not responsible for wireless set up of flow by moen.
