I wanted to report back and say I did install the Rusco 1" Spin Down 100 mesh before the CSV. The system was working very well, and sand build up had slowly declined... until today.
Unfortunately while we were out of town, our neighbor (new construction) hooked up to the water. First day back in town and we just lost water. I ran to the well house to find the filter caked in mud/sediment, something I hadn't seen since the first fire up of the pump. I shut everything off, cleaned it all up, hit the control box overloads, and was very relieved to see the pump fire up, good pressure/flow.
Long and short, I would NOT recommend this set up unless you are 100% sure you won't ever see sediment in your water.
I ran through a few pump cycles with no hiccups but I'm wondering what the likelihood of permanent damage is? I assume it was the thermal overload on the motor that tripped, don't really see how it could be high amperage. Water pressure seemed pretty normal until this morning. Fingers crossed it was a lesson learned.
I guess the question now is if I remove that filter, could sediment potentially clog the CSV at low flows, or is that not a realistic scenario?
