Our water comes from a deep well, and at this time we don't have enough water pressure. I was told that the submersible water pump needs to be replaced but I doubt because it is working. I would like to know how I can fix the problem, and if the pump needs to be pulled out then I need ideas of how I can do it myself, tools that I would need. The main problem to pull it out is the weight of the water pump, and the galvanized iron pipe.
