Well, this coming spring I am going to "redo" some of my system since groundhogs, moles, and other animals really destroyed some of it. I also am going to lay my pipe design out a little better in some areas so I have less pressure loss. And maybe upgrade to a 1" manifold and valves since its 3/4" right now. This will give me another gpm or 2 since the valves are kinda tiny. The laterals are 3/4", but for 3-4 heads a zone I guess thats okay. I'm not redoing the entire system.
When I re-bury my valves, what is the best way to do it. I read somewhere not to drill holes through and pop the pipe through because it will put pressure on the pipes, and break them. Well, that what I did, which is #1 in the pic. And the manifold is bending and warping. Plus, it was a pain in the butt to line up, and I see why
How do the pros do it/how do you do it? I believe its #2, right?
Can someone also link me to a shallow valve box. I need 2 boxes (6 valves) and the boxes I have are 15" deep. My pipes are only 6-10" deep though (varies). Making a big box near impossible to bury. Thats why I had to drill holes for piping. I'd like to lay a shallow box over them when I redo it. The laterals are poly 3/4", so bending them down is possible to a point.
