You can use your existing FlexPipe with Sprinkler 3. We recommend our new swing joint, but a simple adapter works too!
Using a homemade adapter with FlexPipe:
Add Teflon tape to the FlexPipe ¾" fitting
Add Teflon tape to the 1" male end of Sprinkler 3
Connect the threaded fitting to the FlexPipe and Sprinkler 3 and tighten with a wrench
Using FlexPipe with the swing joint:
Add a PVC 1" to ¾" threaded union
Add Teflon tape to the swing joint and FlexPipe threads on both sides of the union
Connect the FlexPipe and swing joint to the union and tighten with a wrench
Connect the swing joint to Sprinkler 3 (no Teflon tape or tools needed)
You can also replace the FlexPipe entirely with the swing joint attachment.
