Could how I have the Transfer pump and expansion tank installed, causing the issue?
The transfer pump will work for a bit but eventually fail.
I'm so frustrated im thinking about removing the entire transfer pump system The only doing direct feed.
I removed the expansion bladder tank from the equation and everything seems to be working better. I guess it's a bad idea to install the tank above the pump..perhaps it causes a Siphoning or airlock.
In this system.
