I have a well with a submersable pump. Water flow has dropped significantly. Pressure switch is 20/40 psi. Air pressure in tank is 18 psi. Pump kicks on at 20 psi, jumps to 25 psi, and continues to 40 psi. However, water flow remains very low.
Problem was first discovered while watering the lawn and noticed that water flow had stopped. Pressure gauge showed zero. I tripped the circuit breaker and waited until the next day. Next day the system worked OK for a while. Then water flow diminished to a level that would not operate the sprinkler head.
Where do I start looking for the problem? Water lines, tank, pump, well?
