I don't recall with 100% certainty - we weren't the contractor or designer, just a third party consultant to the developer. I think all sprinklers were inspected for signs of loading and only affected ones were replaced.

One of the most common bad practices is to make up a bunch of pre-cut drops and clue them into branch outlets assembly-line style. If done in a hurry with too much cement, you get runs that can wholly or partially fill the sprinkler above the plug. I've seen it. SL From: Sprinklerforum [mailto:[email protected]] On Behalf Of Mike Hairfield Sent: Wednesday, July 13, 2016 9:59 AM To: [email protected]<mailto:[email protected]> Subject: Visual Inspection of CPVC System We recently had a local AHJ require a visual inspection of a CPVC system prior to doing a hydrostatic test. All places where a sprinkler head was installed they made us remove the heads for the inspection. Has anyone ever had this happen to them or am I missing something here? Thanks, Mike
