Pressure goes to zero after unplugging pump and will not shut off when running.
We have been having trouble for over a year with our water. We bought a brand new pump 3/4 horsepower. We have an above ground spring fed well about 450 feet away. We bought all new 1 inch pipe. The lift from well level to house level is less than 15 feet. The water runs up to the house, but does dip down about 3 feet and then up about 5 feet at the house, we dug out a trench and most of the line is on top of the ground, but goes down into the trench to come in the house. It will pump forever and give water, but not shut off. When it gets to where it should shut off, it bounces around and sucks back about 10 lbs and goes back up to where it shuts off and bounces back 10 lbs and runs again. When you unplug it it goes back to 0... but pumps up right away when plugged in. I have always told my husband that it needs to be wired differently... it is wired to heavy wire, but then that wire is plugged into about a 25 foot extension cord. It is then plugged into a receptacle... I have always said maybe all our problems are electrical, but husband does not agree.
