Good day, All
I see that running cpvc in a return air plenum for the most part is alright with exception of running the line directly above a return air grille (no cpvc lines to be above the horizontal). It would appear then that running cpvc behind a return air grille on the vertical is ok...
I tried to repost/correct the original diagram but it would not let me... here is a more complete sketch

What is your take on this installation example. No shut-offs on the FDC line, on the water supply side of the check valve, not within a specific zone... or does that base standpipe riser shut-off become a...
May I ask, Travis if there are health and sanitation standards down in Colorado that require the cleansing and sanitization of the grow op areas/rooms and if so how one avoids having the sprinkler heads damaged or furthermore even touched during the process. I believe Health Canada has really...
The one item that first comes to mind is the mixing of these special application sprinklers and standard heads. I have had conversations with Reliable sprinkler engineers and the bottom line is that unless the whole attic can be done with just these Reliable Special App heads a different avenue...
It appears the latest idea in my town is to take existing warehousing (where racking is already standing) and dividing the rack areas into smaller rooms complete with ceilings... basically a group of small rooms with racking inside all within a big warehouse.
The couple I have been asked to...
Actually 33 - 9.4.6 of 2016 Clarifies the spacing within ducts to 12' horizontal and at the top of an exhaust riser to a maximum 24'. No clarification on calcs within a duct on OH2 permissible systems though.
As per NFPA 13 2013, 22.4.1.2 "exception" one can design to Ordinary Hazard 2 for powder coating but does not get into the ductwork portion of the design . I would imaging the 30gpm/15 psi would still apply but seems to defeat the purpose of the exception.

Good Day, All!

To anyone who may stumble upon this for similar issues: As per Sprinklerdesigner2 -
26.4.4.1 is to be applied to marine type systems.
8.15.1.2 and in this case specifically 8.15.1.2.1 would apply - and although quite similar to 26.4.4.1 - 8.15.1.2 does allow for minimal combustible loading...
nfpa 13 2016 8.12.5.2 #2 says no coverage is required underneath (the obstruction) if the obstruction is 24" or less in width and located horizontally from the sprinkler at least one foot. To some of us "horizontal" means at the same plane but others argue that it is one foot horizontal and at...
How close can a radiant tube heater be installed (above) a sprinkler line/main before it becomes troublesome to the sprinkler pipe and closest sprinklers and fittings (couplings and gaskets).
Hello, All
With the NFPA 13, 2016 (8.15.26) and tyco shops clarifying what can and cannot be done in regards to glazing protection is there any other option for glazing protection on a set of windows with horizontal mullions? The architect's up here in my land want to use Glazing protection to...
