I bought a property awhile back. It has a municipal water system now to the house. The previous owner told me the well worked when it was disconnected. The well is in a covered pit outside. I opened the pit and everything was there, but the pump was rusted and of no use. This well has not been used for over thirty years. I pulled out the plastic pipe(the injector at the bottom was also rusted away) and measured the depth. It is 150 ft deep with 70 ft of water. It has a 4in casing. It had a 3/4 hp deep well injector pump.I need to replace everything but I was wondering what I should do or how to go about restarting this well. I was thinking of just replacing and running it but was concerned about damaging a new pump. Any suggestions will be greatly appreciated. This well will be used for the lawn and for the garden.
