In your video, the CSV and tank are installed inline between the well line and the house line.
So I'm thinking about adding the CSV to my existing 81 gallon pressure tank, or getting rid of it and using your small tank. My pressure tank and pressure switch do not sit between the house line and the well pump for whatever reason. The pump line comes in and splits to the house before the pressure tank then continues on into my garage and connects to my pressure tank. Can the CSV simply be hooked up the same way as my existing system? thanks!?
