Protecting system from Entergy trucks
I'm planning on installing an irrigation system in an electrical servitude. I'm pretty sure that a power pole near the area will have to be replaced within the next 5 years (completely rotted through), which means a large truck will drive over (and probably park on)the pipe.
Will 1" S40 PVC pipe burried 18 inches be sturdy enough to handle this? Should I look into flexible tubing? My neighbor's water line (PVC) was broken last time they drove through, but that was at the point where it meets the meter.
I'd hate to install this system and then have to dig it all up again in a few years.
I plan on hooking the irrigation to an outside spigot. What kind of backflow preventor do I need? (I was told a simple check valve would be fine.)
I'm planning on using an air compressor to winterize the system every year. Do I need a pressure relief valve in addition to this?
How necessary are pressure regulators? (I'm using city water.)
I havn't actually done calculations for water availabilty/capacity- would it be a safe assumption that I don't have to worry about it as long as I am just doing 200 ft of shurbs and veggies?
