| Notes: |
Gluing Pipe and Fittings
Make sure all surfaces that are to be glued are clean and dry. Apply Primer to both surfaces thoroughly and evenly. Generously apply glue to both surfaces, quickly pushing them together while twisting (about a quarter of a turn.) The glue will dry in a few seconds, but will not reach its full strength for about 24 hours.

Threaded Fittings
Apply thread sealant (teflon tape only) on the male threads, twisting the fittings together until they are finger tight--not hand tight. Tighten the fittings one to two turns more to seal the joint completely. Over tightening can easily break the fitting. Most manufacturers recommend not using pipe dope--and will even cancel their warranties if you do.
· Buy Fittings
· Buy Teflon Tape
Installing Drains
Drains should be installed at the lowest points of each lateral line. Install them at a 45 degree downward angle to allow for proper drainage. With drains, "more is better." They will save time, trouble, and added expense later.
· Buy Line Drains

Flushing the System
Fushing the system is very important; it clears the pipes of foreign debris that will clog the system and cause problems later. Before installing the valves, flush the mainline thoroughly by turning on your stop & waste. (Make sure that dirty water can not re-enter the mainline.) Before installing the drains and sprinkler heads, flush all lateral lines by turning on the valves manually.
· Buy Stop & Wastes
· Buy Valves
· Buy Line Drains
Installing Sprinkler Heads
Be certain to install the plastic screens in each sprinkler head before you attach the nozzle; they help to prevent clogging and affecting the sprinkler performance. (Some manufacturers pre-install the screens for you--please check.)
· Buy Sprinkler Heads
Electrical Wiring
Protect the wires between the controller and valves from damage by attaching the wire to the underneath side of the mainline, or by running it through conduit. This will save you time and money in the future. Use tape to secure the wire in place.
· Buy Wire
· Buy Wire Connectors
