We blow out at full line open, usually that means 50 to 75 Psi back pressure. When we fill or reset the valve, we use radio's with the valve just cracked at the compressor. Fill usually takes about 2 minutes. We leave the air couplings on the drum drips, but not the insp. Test. Then we're pretty sure they will be there next time.

I was aware of the sizing requirement and not really sure these tank mounts are meeting it, but again haven't done the ciphering. So I guess there really isn't any "limit" on # of systems as long as the compressor is big enough. Great idea on the trailer unit btw, I just bought an 8HP gas driven ridgid but it's not a big tank unit like one of those. I guess you rent it, I suppose I could too. Might be smart (smaht) for the summer full flood trips for us. Thanks! I put a bee on their bonnet on the central units with dryers, we'll see where that goes. Another thing this new one has is he put sillcocks with 6' washing machine hoses behind each pair of valves. Talk about making priming easy! We used to drag a hose in but this guy's already made life easy. The compressors and fill lines were hot when we were resetting them so I can see the benefit of using your own. Great point. Do you fabricate your own pressure regulating assembly? I know most of those trailer units supply 80-120 for jackhammers and such. I think probably 25-35 PSI would be a safe pressure to be blowing out at, sure would be nice to not have to wait 1/2 hr. for it to return.
