Class II & Class III standpipes in sprinkled buildings

[cheyer]

I'd like to get a feel for how other jurisdictions allow the removal of hoses in both Class II and III standpies syatems in sprinkled buildings. Are you allowing the building to remove the hose and cap the 1 1/2" outlet on a class II (or demo. the cabinet all together)or add a f/e instead (if they keep the cabinet in place) Are you only allowing the removal of the hose in a class III (per NFPA 14, 7.3.4.1)......The way it's been explained to me is: if the hose cabinet is fed from the domestic system, then the cabinet can be eliminated...if the hose cabinet is a combination standpipe then the hose can be removed and a 2 1/2"-1 1/2" can be installed. Obviously, non-sprinkled buildings will have the hose maintained in place.

Thanks.

We allow hose removal via request letter for documentation. The facility must cap and provide approved signage and in industrial (without brigade) paint drop piping red and provide signage.
