I need to shut the house water supply. I want to change a Moen single handle cartridge. I have a private well outside with a pressure tank and Rayne conditioner in the garage. I have no idea which valves to turn. There is a large valve attached to a pipe coming from the pressure tank, a ball valve attached to a smaller pipe that indicated flow to the conditioner head and finally two valves at the back of the conditioner head.
