We always used the TOLCO fig 25 surge restraint with loop hangers to the CPVC. This maintained the proper gap, while not making fitters fight the pipe/pitch while hanging. When I co-taught a blaze master class, it was amazing to me how many guy's had been installing CPVC but because they didn't know seismic they never thought of using the FIG 25's.

My Lubrizol guy is actually coming in tomorrow to talk to students and I'll try to remember to ask him. _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field)
