Dear All,

Good morning,


I would like to ask, if I have a riser, can the alarm check valve be replaced by the check valve?

In link below there is a listed valve which contractor want to put on the riser in replace of alarm check valve.


But I have doubts is this is correct and I can't find a clear information in NFPA 13, is there should be mandatory installed alarm check valve on riser or check valve also allowed.


Best regards
