Mike - on megas like yours, that will work. For 95-99% of the blow outs here, spending extra time which relates to extra charges, is going to mean a lean winter due to no blow outs. I walk around as much as I can and look/listen for leaks, especially on the drip lines though.
I did get a mega today, that I will have to go back for. Existing customer bought on a foreclosure and is fixing it up. 50+ zones, but get this. 24 are on the controller, and more than 25 Hunter battery op valve/controllers
Good thing is there was a sticker on the controller from a previous company working on it and I called him. He is going to give me some advice, seeing how I loaned him my backup compressor for four days.
