My anti-siphon valves need to be 18 inches (half a meter) off the ground, due to local code, the water source and the slope of the yard. There are three valves connected to a horizontal manifold and I was given mounting brackets to screw down over the manifold. So now the trouble is, what to screw them to? This isn't very close to the house or I'd affix a board on the wall and screw the pipe to that.
Does anyone have experience designing and building something solid to hold the irrigation valves up? The incoming pipe and the manifold itself are nowhere near strong enough for the valves to just hold themselves up, and the outgoing pipes are flexible by design.
