Thank you for simplifying for me. Currently there is a 25psi regulator on the system which I will remove unless you advise against it. I’m using Hunter’s inline drip tube with pressure regulation and check valves.
There are 16 zones but only 2-3 that are raised. Some of the runs are quite long.
I try to recommend the best products to my irrigation clients. Please describe the specs of Pump Relays or send a part number or link and please suggest the best brand 1 Hp Booster Pump.
@tcremer - the calculated worst case supply water pressure is more than the regulator, so I think you’ll be fine without any additional pumps. I would keep the pressure regulator in the system.
As an example here is a pump start relay from Home Depot (also available from Lowe’s, etc.):
“Best” is subjective to the purpose at hand, etc. Regarding pumps, I’m not sure which are designed to operate with input pressure (i.e. from the municipal water source) versus drawing from a lake or body of water. Most of the pumps capacities seem like overkill (i.e. GPH) for this application.
I think I will change the pressure regulators to 40gpm so it doesn’t have a chance to decrease the pressure if it’s over 25gph. Which are the best pump companies?
