#Deluge valve internal inspection for 60M or 5 year frequency

 

NFPA 25H 2017 13.4.4.1.4.1 Internal inspection of valves that can be reset without removal of a faceplate shall
be permitted to be conducted every 5 years.

 

Can we use borescope to comply the above points instead of removing the DV from its installation, in some sites the deluge valves installed in complex way. Removal and re-installation of DV will be harder.

 

Also, could you anyone please justify the purpose of the internal inspection?
