    Low water pressure in a well system
    I just moved out of town and am on a well system for the first time. I've been reading about them quite a bit to learn how the installation works. We have pretty low water pressure and find ourselves running around in the shower to stay warm, which is unacceptable to my wife. To describe our system, we have a submerged pump that feeds into a storage tank, no bladder, not a pressure vessel either, and a Grundfos MQ3-45 feeding the house. I have 60PSI in the system but the moment a faucet is opened the pressure drops below 30PSI and doesn't recover. I am hoping that I don't need to scrap the storage tank and get a pressure vessel, but the more I read the more I am convincing myself that is what needs to happen. Any advice?

    You are running a Grundfos MQ3-45 booster pump. It is made to take water already under some pressure and "boost" that pressure up higher. You are feeding from a storage tank which means you probably have little to no pressure at that point. I'm tempted to say I would put a pressure tank after the booster pump, but it seems that the pump is simply not able to deliver enough water to get to even 30#, so a tank might not help so much. How old is the pump??
