Installing the Valves
If you are installing a new in-line valve manifold, or grouping anti-siphon valves together, keep in
mind that the location should be easily accessible for maintenance. Locate the manifold where you
are not likely to be sprayed by the sprinklers when turning the system on manually. On larger sys-
tems, separate valve groups may be required for the front and back yards. It is a good idea to keep
a plan showing where all in-ground valves and pipes have been installed.
Important:
Be sure to flush the line coming up to the valves, before installing the valves.
Tip:
If using a manifold for underground valves partially assembling the manifold ahead of time will
make the job easier. Be sure that the valve is installed horizontally according to the arrows printed
on the body for the direction of flow. Valve operation may be erratic and valve warranty is void if in-
stalled backward or in a vertical position. Do not over-tighten or use any kind of pipe dope. Call our
