fire hose reels

[sheff paul]

Trying to trace a cold main on a commercial refurb,gaffers away so on my todd for a few days,had nothing to with fire reels,2 questions,can you fit them in a building fed on a cold supply fed from plant room boosted cold feed,as at moment they are fed on the mains,but they want booster sets fitting.

Normally there taking them out and fitting risers as the fire lot don't want have a go Heros

Wont that leave deadlegs of stagnant water?

As above, we're taking them out more often than not. The feed for the hoses is usually capped off where it splits from the main.

Or as close as possible if in concrete floors

get a tidy sum for the bronze ones

They are still fitted, albeit not half as much as they used to be and generally are being removed for the legionella risks the impose. Mostly they are now only fitted where the largest type fire extinguisher is insufficient to create a safe exit.

Back to the question. I would suspect they would have to be on there own dedicated boosted supply (i've fitted Grundfos in the past) not on a shared domestic BCWS, because if someone has it shut down for maintenance, other than hose reel maintenance there is not going to much water out the end of it. Hope that makes sense?

Fire stuff is quite a specialist job. Nothing difficult about it but not something you can wing it on as it has to be properly designed (and signed off).
Basically you can't/shouldn't have hose reels fed directly from the mains anymore as the mains won't meet the delivery requirements.
Needs to be tank fed (2 tanks) and pumped (duty and standby) to min 8 bar and 1000? odd l/min and also the tanks usually need an emergency fill point too that can be fed from the fire tender.
Its quite a specialist thing.
