Spray check valve

What approximate elevation change requires check valves in lawn sprays with mps.

Doesn't take much at all. I pretty much use checks on new installs. Even on yards that appear flat usually have some elevation change. One pet peeve of mine is a wet spot from low head drainage.

Its shocking what a few feet of elevation change will do for low head drainage..

All but the highest 2 is what we usually do.

I third this.

Pressure regulation and x-flow while your at it.

Just buy the most expensive head you can find, remember: Energy CANNOT be lost. Thus no matter how expensive, nothing can be argued as having been "wasted". Money is just a form of energy....
