Pipe, is the flow switch electric, or non-electric to operate? and where in the line would I install it? I suppose my concern is if it does go dry, it would be nice to have something stop the system. But, I also plan to install a gauge on the tank in order to check the water level(s). I'd like to take the easy route, but I'm thinking I may have to intall the 1 1/4" from water tank to pump.
Another question: at the end of the hunting season (say Dec. 1st), I drain the system for winter. In the spring, when I recharge the system, and run the pump to re-charge the water system, it'll be running dry until the water is obtained and flushed through. Will this hurt the pump, or is it a givin, becuase that's what it purpose is? I suppose the main thing is that the pump is run dry all the time, correct?
