I finally got joined on this forum! You folks seem to be a wealth of information and can hopefully shed some light on my dilemma! Long story short, property sat for a couple years water unused. Been working on it for a while now and water pressure is low and volume not very good. Decided to try and fix it! There are many sand points in the area that produce very well, (no pun intended). In fact there are 4 houses with shallow wells within a couple hundred feet of me. Well are in the 30' depth range and have worked for many years. Any way back to how I got here. Drove a new sand point with two stacked points and 25' of pipe. This produced some water but not much volume or pressure, to the point the demand boiler would stop heating water due to lack or pressure differential.
So I pulled the point out to get a look at it. Came out very hard!! The point was partially plugged with slurry looking sediment in the bottom point. Cleaned it up and started driving it back down with the single sand point and 1 1/4" pipe. I should mention there is water at 10' so my static level is 10' this is where it gets confusing to me! I drove down 20' and 3' point and could not prime the pump, that was a week ago. I have continued adding 5' sections of pipe and driving them down with a 25# slide hammer we made many years ago just for this. Soil very sandy, near a lake currently I am down to 38' with the point and the pipe will not take much water on and drain itself down, it drains slowly and that explains why it will also not hold a prime. Last night it would prime and slowly build pressure, specs were 30 - 50 set for the pump and it was pulling 27" of vacuum. It would take 15 - 20 minutes to build from 28 to 50#'s, way to long of course. Pump is Flotech 3/4 HP cast iron jet pump on a flotech 30 gallon? pressure tank set at 28# using 1 1/4" galvanized water pipe with drive couplers. One way valve is on the horizontal side of a T going into the pump nozzle.
Big question, why am I having to drive so deep and not getting good volume/pressure? The original sand point was down about 25' and is of unknown age.
