I have a 4" steel cased well towards the back of my property. It evidenly hasn't been used in a number of years. There was a mobile home there at one time, the well is on my side, the septic system on the neighbors. I'd like to use the well for garden irrigation, but it's 500 feet from my nearest electicity, and there is no pump in the well. I just dropped a string and a weight, and the water table is at 16', and we are really in a dry season. I have a good Multiquip 3" trash pump powered by a 8hp Honda. Specs say the pump will handle 25' of suction lift. Talked to a local well driller the other day, and he advised that if the water table is 16-17' it would work fine. I have no idea how deep the well is.
Here come the questions:
If I put a drop pipe down in the well and plumb the pump to it using PVC and aflexible piece between the pump and the plastic, will this pump enough water for irrigation? If so, should that drop pipe be 3" or 2" ? ID of the casing is 4". How long does that drop pipe need to be? Let's say I drop 20' of 2" pipe in the well, (or would 3" be better?) can I use the 20' suction hose that fits the pump onto that, or would that be too much head?
