[Sprinklerforum] Re: Floor Control Valves

A lot depends on the year of the standard being applied, but YES an AHJ can (and should) require things that make sense for his/her community and the methods used or planned for fire and EMS responses. In this case, you are on solid footing because NFPA 13 (2019 edition) section 16.9.11.1 requires

[Sprinklerforum] Re: EH 11k & High Temp RA reduction

Micah, I understand your project will be reviewed based on the language in the 2029 edition of NFPA 13. However, section 1.5 Equivalency allows you to use alternate arrangements with technical documentation submitted to the AHJ. What better way to show the level of safety is not being lowe

[Sprinklerforum] Re: Modified 13D System per FD

I am not sure, but I don’t believe I’ve ever seen rules related to wagering on the forum. I do not believe it would be appropriate however, in the unlikely event of “off-track” betting on the outcome of a code application, the house should get 10%. No vig.

Re: Slow responding dry pipe valves-FDT

I'll admit I have not read all of the postings related to this topic but that’s never stopped me from chiming in before Residential dry pipe systems for 13D, 13R and 13 are on the horizon according to the manufacturers. One even advised the committee of an impending listing for their CPVC

RE: Dry Valve Trip Test - NFPA 25

Do you other than NFPA 25 24.2.3.2* Dry Pipe Systems. 24.2.3.2.1 A working test of the dry pipe valve alone and with a quick-opening device, if installed, shall be made by opening the inspector's test connection. 24.2.3.2.2* The test shall measure the time to trip the valve and the time f

RE: Southwest Airlines FALSE advertisement

I saw the commercial and I thought it was funny. I don't understand why we get so upset as an industry when we see these un-realistic depictions of sprinklers. It's not like all the other comedic stuff we see in advertising or sitcoms represent reality... besides, it gives us an opening to fur

RE: How do you test a pressure reducing valve on a standpipe?

Potter Roemer (and probably others) sell a test device that looks like a play pipe but it's got one gauge to measure pressure and one to measure flow so you can set the pressure at 250 gpm flowing Craig Small <[EMAIL PROTECTED]> wrote: > Forum members, > I need some help a salesman sold

The floating ceiling question is commonly asked during live seminars... if the ceiling is floating and not attached (connected to; touching) the walls, the area above the ceiling is required to be protected regardless of the type or combustibility of construction. Bob Caputo [EMAIL PR

RE: residential heads / 4 head calc

Sorry to jump into this late, especially if this has already been resolved. It is NOT permissiable to utilize the room design method with residential sprinklers. The use of residential sprinklers and the hydraulic design approach are found under special design approaches in 11.3 The room desig

RE: 3/4" Steel Pipe on Dry Pipe System

There are great benefits to replacing 3/4" end of branch line piping with 1" piping, especially since there are reasons the standard doesn't allow 3/4" steel pipe any longer. It's easily plugged with minimal amounts of debris and easily ecluded over time. I agree with you Rick, its a good id

Re: RE:Quarterly Inspections

Mike, not sure where you got that unless you're thinking about weekly inspections requirements for control valves that are only sealed versus monthly inspections for control vavles that are locked or tampered... it doesn't ring a bell for me either. Bob Mike Wisneski <[EMAIL PROTECTED]>

RE: BUSHINGS

Actually, the 2007 edition of the standard was changed slightly in this regard. Please see the following sections. 6.4.6 Reducers and Bushings. 6.4.6.1 Unless the requirements of 6.4.6.2 or 6.4.6.3 are met, a one-piece reducing fitting shall be used wherever a change is made in the size of th

There was a proposal submitted to the committee during the last open cycle (2007 edition) where the submitter recommended changing the 52,000 sqft limitation to 150,000 sqft. The proposal noted that 3 floors of 50,000 sqft each, with one control valve in permitted now - so why not permit the sa
