We were having problems with our well pump supplying very little water to our house. (About a gallon to three gallons every 20 minutes or so, then nothing) So we replaced the old 3/4 HP submersible pump with a brand new one. Now the water doesn't even reach the pressure switch.(NO water coming through the faucets) It is a new pump, there is water in the well, and no leaks in the water pipes. What could the problem be?
