FYI... i also am a well driller. A 17 year old pump and tank are on borrowed time in my area. What exactly is that picture? Looks like a black 5 gallon bucket with a “Rusco” type sand separator filter your cleaning out? I would consider a price from your well service tech for a constant pressure system to operate the house and Geo system. The Grundfos SQE line are generally my Favorite for residential open loop systems. You will benefit from the constant pressure in the house too.
