I've worked on a system for a few years fed off a well. Pump went out recently and well people will be replacing this week. Pump is 5hp run through 2" pipe. System is HO "Special" he was a genius, might have been a train driver at some point. I've just been nursing the system and going with as is but I see the opportunity to maybe make some improvements or at least have an idea what's what. With 5hp I'd imagine some of the smaller zones are way over pressured so maybe some sort of pop off pressure bleed? What would you recommend? Other ideas that might make service easier later since piping at pump will be done over.
