The easy wire system simplifies wiring the connections between the sprinkler system valves and the sprinkler system timer. Jar top valves are included for easy valve maintenance. The sprinkler system manifold is highly durable because it is built with high impact UV-resistant material. It works with both 3/4 inch and 1 inch sprinkler systems and installs in minutes. This sprinkler system manifold requires no tools-all the parts can be assembled and tightened by hand.
