Here You Go "PM Dude" ;-)

Received a PM from a member asking how we transition from old galvanized pipe risers to our swing joints. Here's some pics where I removed a non-rotating Toro Super 600 and installed a Hunter I-20 ADS in its place.

We leave the riser intact and use a galvanized 90 ell to start our swing joint. The galvanized 90 screws onto the galvanized riser better as it catches the threads, even these that were well bunged up. Some will try and thread a PVC thread x thread 90 ell onto the galvanized riser but chances of cross-threading the PVC are great. We just use a galvanized 90 doped with a little Rector Seal and are done with it.

We carry 1/2", 3/4" and 1" galvanized 90s just for this reason. If we remove a sprinkler and the galvanized riser separates at a coupling (where you'd have a female thread starting point instead of the male threads of a riser) then we use an extra Marlex 90 in place of the galvanized 90.
