I'd appreciate some advice.
What's the best way to regulate pressures on a combined sprinkler (OH2) and Class 3 standpipe system?
Obviously the pressures required vary between sprinklers, 2-1/2" standpipe outlets and 1-1/2" hose rack connections.
Pressure regulating valves are expensive to put in on all connections, but I was thinking about using pressure regulating valves for the 2-1/2" standpipe outlets.
I think it's great that we can all share our combined experience on this great website - thanks in advance!
