Re: Floating Dock

Hello Charles, See if I can get all the answers in this email: It is schedule 40 now and had to be centered in the floating section to keep it level, This will be 4 feet off center. There is no handrail on the floating section so it will be mounted to the deck with 2' risers to the hose

Re: Pressure Reducing Valve on a Balancing Calculations

Hi Jerry, Have you considered using a pressure sustaining valve on the supply side of the pump? It has the effect of limiting the pressure at low flow, then opening up to full pressure at high volume. I believe you would need to locate the valve upstream of the pump outside of the pump house to

Pressure Reducing Valve on a Balancing Calculations

I have a Fire Pump feeding a HiEX foam and Wet System. The start-up churn on the pump will cause the pressure to go over 175 psi so we are putting a pressure reducing valve on the wet feed side of the discharge. I'm not sure how I balance this system anymore due to the PRV. The valve will be

I've never actually installed it myself. Priced it once. But I see it all over. Yes, typically under the floating docks feeding hose valves from below. John Irwin Critical System Solutions Sprinkler Construction Manager 813-618-2781

Floating Dock

Hello Sprinklerforum, Looking for suggestions for pipe to use on top of a floating dock for the Manual Dry standpipe. We had pipe under it but due to structural failures of the dock the pipe is now in 3-5 feet of muck in the bottom of the river. Looking to run the pipe on top of the dock.

Re: Unsprinklered spaces in strip malls

Replying to SL's comments re: Individual shut off and flow switches to individual tenant spaces in larger malls. True malls, larger than 50k sf have required active smoke control. Automatic detection is required. This may be by smoke detectors, or by flow switches configured as observed by

RE: Unsprinklered spaces in strip malls

In a perfect world, they are not getting an occupancy permit on the “vacant spaces”. In that case it could be looked upon as no occupancy, no fire hazard. If the spaces are vacant with no combustible load and no occupancy, it behaves much like a noncombustible concealed space above the ceiling.

RE: Unsprinklered spaces in strip malls

Because if it’s a non-combustible building and the owner isn’t trying to obtain a certificate of occupancy for the rough tenant suites, then they can request final inspection on the common and back-of-house areas and defer the tenant suites. It’s actually a low-drama scenario at the statutory

Would it not be conceivable that the building owner is simply deferring the cost of the sprinkler installation to the individual tenants when and if they lease a shop/space in the building? Mark at Aero 602 820-7894 From: Sprinklerforum [mailto:sprinklerforum-boun...@lists.firesprinkler.org]

Whether or not the swiss cheese passive construction is tight or not doesn’t change the owner’s building code driven options. Their insurance carrier will obvious adjust their premiums accordingly. I never said it was the smart thing to do, just that it is allowed. I was one of the initial

Re: Unsprinklered spaces in strip malls

I think the building code would allow, or could be interpreted, to mean what Roland is alluding to in his short post. Then the same with Steve. Is the AHJ calling for sprinklers per occupancy definitions in the building code? You can make a case that in a mixed use you need a OH2 in the auto-parts

Re: Unsprinklered spaces in strip malls

I did an article in 2013 on when different parts of a single building can have different levels of protection. IT started off with when you could have a portion with a 13 system and others with a 13R. It morphed into when you can have parts with NO protection. Shoot me an email off line if

RE: Unsprinklered spaces in strip malls

Careful with that claim Shawn. NFPA 13 does NOT require a building or part of a building to be furnished with sprinklers, just as NFPA 14 doesn't require standpipes in buildings and NFPA 20 doesn't require pumps on FP systems, etc., etc. The adopted building code requires sprinklers in
