What We Recommend
We recommend 1 Mainline Drain located on the water supply piping after the backflow device but before it splits up to head to the control or zone valves. We also recommend 1 lateral line drain, and 1 to 2 end of line drains per zone or section of the sprinkler system. You should not exceed more than 3 to 4 drains per zone or sprinkler section.
