FIMCO snap-on saddles are an easy way to add sprinklers or vacuum breakers to a new or existing irrigation system. There is no need to cut pipes and add T fittings.
Here’s the procedure for installing a FIMCO snap-on saddle with a vacuum breaker:
- If the saddle came with the vacuum breaker installed, first unscrew and remove the vacuum breaker.
- Apply PVC cement to the underside of the saddle.
- Snap the saddle into place at the high point of the system, the majority of the time this will be just before the indexing valve itself. The 1/2″ female threaded portion of the saddle should be pointing up.
- Allow the PVC cement at least 2 hours to cure fully. All PVC cement manufacturers will list their full cure time on the can. As always, we recommend against the fast-setting blue PVC cement; it’s incredibly aggressive towards ABS plastics and, if not careful, can create more problems than it solves. We recommend standard clear PVC cement.
- Drill a 1/4″ hole into the pipe through the 1/2″ opening in the saddle. Avoid the threads on the saddle, of course.
- Apply a few twists of Teflon tape to the threads of your vacuum breaker, screw it into the saddle, and you’re done.
