I have an Orbit manifold which I just installed. The pictures you will see below do not show the final state of the whole thing ...this is work in progress.
In the pictures below you can see that instead of buying one of the overpriced Orbit manifold boxes I build one using tiles and PL adhesive. The idea of this design is that the cover, which you see in place and on the side in the second picture, will serve as a planter for ground cover. This is designed to hide the manifold box. So that cover/planter is 17"x18"x1.5", it will be filled with soil and ground cover (same as what is currently around the box. With these being said and done, the cover/planter will become a little heavier and I am thinking that for easy access I should add some handles. Right now I am inclined to glue some nylon rope on the back side of the planter like in the third picture
