We were using our water all afternoon when it just stopped working. We changed the filter, checked the contact points-it seemed like it was fine, but then pressure dropped to zero. We got it working again downstairs but it wouldn't work upstairs and pressure started dropping again, then nothing at all- upstairs or downstairs. We have only lived here 6 months, so we don't know a lot about the system, but it's supposed to be a spring feed well. Any help at all.

There are several things that could cause this problem. The worst of which is that your well does not have enough water to meet your needs. The simplest could be that you have blown a fuse to your pump and it needs replacing. In between are many things, most of which would have to be checked by a Technician

We have left the water alone and the pressure rose back up and dropped as soon as we turned it on. It hasn't been used for about an hour and it is back up again, so I think we are going to wait until morning and see what happens.

There is a problem called "waterlogging" this is when you loose the air in your tank, and it is filled with water, since water cannot be compressed, when you turn on the water just a little comes out because the pressure bleeds off quickly but if this is the case your pump should kick in and pump as long as your pressure switches are working as they should.
If it is water logged you need to get air back into your tank or you may have a bladder tank and the bladder had developed a hole in it.

Letmetell is correct in describing a waterlogged tank. I don't, however, think that is your problem. A waterlogged tank will start showing up as pressure dropping rapidly for a few seconds, then rising rapidly for a few seconds, and just continues doing that as the pump has to cut on and off every few seconds. LSU, the big question is this: When the pressure drops to zero, is your pump coming on or staying off? If the pump is not coming on, then I would first check the little pipe going to the switch. It may be clogged with mineral deposits (technical term for this is "crud"):) . If so, then the switch cannot sense when to cut the pump back on. If the pipe is clear, but the pump is not cutting on, then are the points closing as they should? If they are closing properly, and do not have corrosion on them, then you start wondering about the pump.

If the pump IS cutting on, then it could be a lowered water table that results in the pump running dry. It could also be obstructions or leaks in the well pipe that make it hard for the pump to deliver any volume.

BTW, is the pump above ground or in the well?

I hope you understand how hard it is for a Mississippi State fan to help someone identified by "LSU", but my Christian faith requires me to do so!! :cool:
