Thanks. That's where I posted it first but that forum doesn't get a lot of action. And I don't know if you are familiar with MasterSpec but they recently moved the gas piping specifications from Division 22 Plumbing to Division 23 HVAC....so I figured I'd post it here as well. Here's a link...

Hi, I'm looking for anyone who had an experience, good or bad, with ProPressG for steel natural gas piping. Thanks.

Thanks bimr!

Thanks LittleInch. If it sounds too good to be true....

Thanks Ashtree!

Hi, does anyone have any experience with the IOREX "piping solution"? They claim it prevents and removes scale, rust, bio-film, etc. I was just wondering if it works. Thanks in advance.

I agree with you.

Thanks Jason, I'm waiting for the owner and Architect to respond to those exact points. Still, the separate sprinkler zone requirement from the report still bothers me.

I'll do that, thanks for your help!

Thanks, I think I'm clear as far as code required coverage in the elevator shafts which are, as you said, very dynamic and as always, the elevator inspectors could have their own take on it as well! Anyway, the referenced standards/codes are 2007 ASME Safety Code for Elevators..., 2007 NFPA 13...

Hello all, We are replacing a bank of elevator cars and their associated controllers, machines, etc. in their entirety. The elevator machine room is served by several branches off of an existing preaction system which serves a large mechanical room, on the same level as the elevator machine...

Thank you!

Maybe for testing the most remote standpipe??? Other standpipes would just have one?

Hello all, Does anyone know why Figure A.7.3.2(d) in Annex A of NFPA 14 2007 shows two hose valves? Paragraph 7.3.2 doesn't require two valves. Later editions only show one hose valve but here in PA we follow the 2007 edition. Thanks, Ken

Honestly, no joke. I couldn't believe it myself.
