Wall Hydrants
Wall Hydrants
(OP)
Does NFPA define hydraulic criteria for wall hydrants? I have looked, but if it's there, I missed it. There is a FPE involved in this project, so I have asked him to define the calculation criteria. I was just wondering if I overlooked it somewhere.





RE: Wall Hydrants
Where will they be located?
How many??
Who is requiring them???
RE: Wall Hydrants
The hydrant is connected to one of the existing sprinkler cross mains. I'm fairly certain that the current pipe sizing (mostly 4") wont support the wall hydrant alone, much less the wall hydrant and the sprinkler system.

How many outlets??
And take it the entire building is sprinkled???

ther was an fdc to pump through, but???
It was also tapped off the fire sprinkler system.
do not think you overlooked anything out of nfpa, guess someone needs to tell you how much water and pressure they want.

Cdafd: Thanks for your help. I'm going to get the FPE's input on this.
Newtonfp: I think that is the way to calculate it,I believe you hit the nail on the head.
