I am trying to help my brother-in-law. They have a cottage on a lake. They pump water from the lake into an old dug well they use as a holding reservoir and to allow sand to settle. Then they pump the water into the cottage with a jet pump to provide a pressurized system. The house pump is in need of replacing. I noticed that it is set up as a deep well with a suction pipe and a pressure pipe, but the well is a shallow well probably no more than 40 feet deep. This would mean that the jet assembly would be down in the well.
Is it possible to change the pump out to a shallow well pump using only the suction line while plugging the pressure line and leaving the jet assembly in the well? They don't have much money so I am trying to work out a way to not have someone come out to work in the well as there is no way to pull the pipes out the well by ourselves.
If the pump must stay in the deep well setup, would it make much difference to leave the old jet assembly in the well and use it with a new pump? Probably loose some efficiency, but I don't think that would matter, would it?
Can someone help us out here, thanks.
