The issue is that an unrestricted spigot is flowing 2 gpm. Two years ago it would have flowed close to 4 or 5 gpm.
A Grundfos 5S10-22 is hanging on 1" Schedule 80 PVC at 520'. The static level is presumably around 180'. Cased with 4.5" PVC from 40' down to 790' total depth. 20 years ago, when well was completed, the TEST DATA sheet read: STATIC LVL 180', TIME 30 MINUTES, RATE (GPM) 7, PUMPING LVL 195'
I plan to pull the pump. I expect to find a crack in the pipe, since this pump is rated for around 4 GPM at that depth, and I am only getting 2 GPM.
I would prefer better household pressure. I would like to have a 50/70 at the pressure tank. So when I reset the pump I'm thinking about removing 8 sticks from the string, and reducing my pump depth to 352', rather than the 520' it's set at now.
SO, I'm wondering, why would they have set the pump so darn deep?
