I'm assuming it would collect in the tank...All this air that is going through the system has to go somewhere. Does it spit out of the faucets or does it reamalgamate into the water?
I don't know...what I do know is that when I replumbed the pump, the water level in the stub was at the level of the concrete in the garage, maybe 18" above the top of the well. The check-valve at the well-head managed to hold that for ~3 years of zero activity. After priming the pump for the first time, it drew water without too much excitement.As for what it takes for a pump to lose its prime, that varies. Given the description of the drop pipe, the air that was in it at various times of the well's existance had to be removed by the pump without the pump losing its prime using perhaps as little as a gallon of water to start. Perhaps the pump being the high point means the water prime falls away by gravity.
Nope, he was relying on his recollection and data they had for this well...so, maybe that's as good as nothing at all.Did the wellman pull the drop pipe to confirm the depth or are you relying on his recollection?
