Hi, I have 2 off grid cabins 70 feet apart with a 1700 gallon cistern and a Flotec 1/2 hp pump with bladder pressure tank. Pump is set to 30/50 with 28 psi. in bladder. Pump/pressure tank is in first cabin and pressure/flow is fine there. 1” pex is run between each cabin. The problem is at second cabin which is slightly downhill from first cabin. Water pressure/flow starts fine for about 60 seconds then stops for about 20 seconds then starts again for 60 seconds and continues cycle. Gauge at second cabin reads 30 psi when gauge at first cabin reads 40 psi. There is a 40 gallon propane water heater in each cabin. Problem started when cistern was run dry. Primed pump to restart water flow after cistern was filled by truck. I believe air may be trapped in line but need advice before cutting line and installing bleeder valve. Any advice will be greatly appreciated. Thank you.
