I'm assuming that I can use the rods less than 6" rule and omit lateral bracing, right? That would leave 4-ways and longitudinal only, correct? Thank you, Bob Knight, CET III 208-318-3057 From: Sprinklerforum [mailto:[email protected]] On Behalf Of MFP Design, LLC Sent: Monday, September 18, 2017 4:31 PM To: [email protected]; [email protected] Subject: RE: CPVC Seismic Really no different. I doubt you will find longitudinal bracing listed for cpvc. You will have to put a short branch (same size as main) perpendicular to the main and brace that with a lateral brace to act as your longitudinal brace on the main.

This is in CA (a first for me as well), north of San Francisco. Are there any special issues that I need to consider, or do I approach this as if it's not much different than if it where steel?
