Automatic Drains / Line Drains are used to help protect your sprinkler system from freeze damage. How They Work: Automatic Drains allow the water to drain from the pipes once the sprinkler system stops running.
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.
Types of Automatic / Line Drains
Line Drains for your lawn sprinkler system come in several models depending on where or how you plan to locate them on your sprinkler system.
LATERAL LINE DRAINS & MAINLINE DRAIN
Just screw into a standard fitting on pipe at low points on line. Orient fitting and drain at 45° downward angle for optimal performance.
SWING PIPE ELBOW DRAINS
Screw into bottom of sprinkler heads at low points along pipe. Just use in place of a swing pipe elbow when connecting pipe and sprinkler via swing pipe.
END-OF-LINE DRAINS FOR POLYETHYLENE
Clamp to polyethylene pipe at end of line with wicking pad oriented downward.
END-OF-LINE DRAINS FOR PVC
Glue to PVC pipe at end of line with wicking pad downward.
SIPHON DRAIN™
Siphon Drain™ self-pierces and clamps onto poly pipe in just three seconds. Or, it installs just as fast on PVC after drilling a 3/8 in. hole. Grommets available for PVC installation.
