Questions regarding design of new system
Hello and Happy Forth of July! I've read countless threads on this Forum and believe I have a very basic understanding of what I need. I live in the Kansas City area (it can get below 0 degrees F.) and my home is on a lot approximately 70' x 140'. I plan to have 3 or 4 zones in the front yard and 4 or 5 zones in the back.
So far, I've chosen the following Hunter supplies because, it seems they are recommended more on this board than any other brand:
ICC-800-PL timer with rainclik sensor,
8 ea. HPV-101 valves,
16 ea PGB-ADJ 4" rotors,
25 ea Institutional 04 sprays.
After the RPZ, I plan to bury a 1" polyethylene main about 12" deep (well above frost line). Then will use 3/4" polyethylene laterals. I do plan to use line drains on the laterals and main at the low spots. If anyone has advice regarding these selections, I would certainly appreciate your providing it.
Questions I have that I couldn't seem to find answers to include the following:
Should I include a master manual and an electric valve immediately following the RPZ? What is the purpose of the master electric valve?
I plan to build two valve manifolds using sch 40 pvc that would be glued/slipped into the valves. On one manifold, I plan to have 4 or 5 valves. I was planning to use 15"x21" rectangular valve boxes. I couldn't find any larger than that and am wondering whether 5 valves can be placed in the box even though it is rated for 4.
Thank you for your time, patience, and expertise,
Frank
