Antifreeze / pump question
Faucets, low point, fresh water valves all closed...everything closed.
Camco winterizing three way valve installed...I pumped 1 gallon of AF until the system reached pressure and the pump shut off...went around to all the faucets but seemed like I needed more AF so went to pump one more gallon.
The issue is that the pump quit drawing AF. Hmmm.
Out of suspicion I broke the both low points open a crack and there was alot of back pressure.
Still, I could not get the pump to draw.
What am I missing?
