Hi,
I have a small house with a well. In recent weeks the water pressure to the house has dropped substantially. This is true for both the hot and cold water, and occurs at all taps faucets etc. At this point if you turn on a fuacet in one part of the house water flow to other facilities, shower, washer etc. will almost cease entirely. I checked the water pressure gauge at the well pump, and it actually seems to be reading high between 160-180. I have also looked for leaks under the house, and around the well pump itself. If the water has not been used for a while and a fuacet is turned on, there is often air in the pipes. The most confusling thing is that water pressure occasionally will return to normal for a few moments if a faucet is running for a while before dying off again. Any suggestions or ideas on this? All help is welcome

Thanks.
