I'm rebuilding the valve manifold of my residential irrigation system. The existing system seems to have no backflow prevention, so among other changes, I'll be swapping out the globe valves for anti-siphon valves (I'd prefer not to use a double check valve for several reasons).
With all the lateral pipes in the ground already, moving the manifold is not attractive, but raising the bottom of the anti-siphon valves 6" above the highest emitter will put them far enough above grade that even 18" tall valve boxes cannot cover them and still reach the ground.
And covering the valves seems like a good idea since the PVC pipe connecting to the valves and the valves themselves will degrade when exposed to sunlight. Painting provides UV protection, but seems more unsightly than the ugliest valve box and will not protect the wiring from curious little fingers.
Are there any good choices for covering a tall valve manifold?
