pressure problem

Hello, first thanks for the generous help.

I have a sump pump in a well that is connected to three hydrants. For some reason the water pressure is reduces. I was wondering what the possible problems for this could be so I could fix it (i.e. the o rings are worn out and the water is leaking in a drain port or perhaps something else.). I have no Idea why it is doing this. Thanks

There could be any number of problems. I.e., the pump could be failing, there might be a leak, a pipe might be getting plugged. There is no way we can tell you which of these, or something else, is the problem. A bad "O" ring, however, is the least likely of all possibilities.

I am a little confussed.. Do you mean that you have a well pump that is connected to three hosebibs(hydrants, lawnfaucets) and that the pressure is reduced. I have never seen a sump pump connected to any hydrant --ever.

Well mayby it isn't a sump pump. The well pumps fresh water from the water table and distributes the water to three well hydrants outside. These hydrants are not connected to the house. I live where it is cold and the pipes being run from hydrant to hydrant and so on need to be more that 6 feet below the ground. It works by when you open the hydrant from above ground the water flows out but when you close the hydrant it actually closes the water 7 feet below ground where 3 0-rings are located. The water that is in the pipe after you close it then drains down the pipe into a somewhat large rock bed so that it doesn't freeze. I don't really understand perfectly how the system works but I thought perhaps mayby one of the 0-rings where busted so that it was draining in the rock bed even when the hydrant was on. Any other suggestions will be much appreciated
