Pump requirements for pulling water from pond
Pump requirements for pulling water from pond
(OP)
I am doing a project in Hawaii that requires a vertical turbine pump to supply water from a spring fed pond to the fire loop around the building and the water storage tank that supplies the building for fire sprinklers. There will also be a pump after the storage tank dedicated just for the sprinkler system.
My question is: Does the vertical turbine pump have to be UL listed and rated for fire protection, or can we use any type of pump from any manufacturer? I am trying to save the client some money where I can.

Would it be better to just have a feed to the tank from the vertical turbine and then feed the loop (sprinklers and hydrants) from the tank and UL pump?

I would go UL/FM all the way.
Why do sprinkler design technicians sometimes do what they do? Here we have a building, or maybe a series of buildings, large enough to require fire hydrants and a loop around the building, and we're all worried about saving a couple bucks? Why? What exactly is the point?
I have a complex with 600,000 sq ft of storage buildings and for a value what it would take to replace the building (rack storage with 39'-8 peak) I believe we would be safely on the low side if we picked $40/sq ft.
$24 million dollars just for the building replacement alone and we're gonna get all wound up saving maybe $30,000 on the high side for a fire pump? Really, does this like a smart move to anyone here? Take the $30,000 and toss it in the garbage because it is irreverent.
Even if an AHJ told me it would be ok I would walk away. Oh yes I would and at a fast walk at that. We've all see buildings of this size and it isn't hard to imagine $100 million in building and contents. Here we worry about maybe saving the owner a few thousand dollars doing something we know in our hearts isn't exactly the right thing to do even if we have "permission"?
What happens if there is a fire and a fireman with a young wife and two children gets killed? Speaking for myself I couldn't live with that because I would wonder for the rest of my life if it was something I did wrong.
Rant completed.

Contact your fire insurance carrier and Hawaii fire marshalfor their input and they'' state UL/FM fire pumps. Forget Chinese products if cost is a consideration.
