Manual Standpipe Control Valves
Manual Standpipe Control Valves
(OP)
If you have a parking garage with a manual standpipe system [just fdc supplied] with five risers, is there a purpose in putting riser control valves at the bottom of each? I understand the need to isolate a riser in a wet system, but does NFPA 14 require them if it is just manual with no water in it?

My attitude is if there is no constant supply then isolation valves are not necessary.
Four out of five AJC's agreed.
Ultimately it is up to the Authority Having Jurisdiction.

In case, leakage of landing valve how can we replace the landing valve without interrupting the water supply to other zones? If I close the isolation valve at standpipe I have no water at other floors? any suggestion?
Thanks in advance.
