Will this loop design work?
Water source: 1" PVC Main from 5/8" Meter, city water. Tee'd up to a 2' section of 1-1/4" PVC for flow check, which open ended produced ~18 GPM. Static pressure is 60 PSI.
Will be using a PVC ball valve main stop, a double check, and one 1-1/4" Hunter valve with Node controller. This will all tie into a 100' straight run of 1-1/4" PVC, connecting to an identical 100' run, 40' parallel to the first, producing a 40' x 100' loop around the house.
There will be 26 Hunter spray bodies (with 30/40 PSI control) with MP rotator nozzles distributed around the entire loop, ranging from .14 to .27 GPM flows at 30 PSI. Sprays will be 1/2" poly pipe connected in 10' lengths or less. Nozzles used will be MP 1000, 2000, Side, Right, and Left strips.
Total flow at less than 7 GPM. Basing design on 12 GPM and 30-40 PSI. PVC pipe and poly pipe loss of less than 10 PSI. Have not calculated fitting losses yet.
Will build/load test loop a section at a time. Decided to do this just for curiosity as I have built a few dozen systems based on normal, multi-zone, designs with wall mounted controllers. First time using MP Rotators.
Do you think this will fly?
