Hello Members,
We are installing a new wet system. Off of the wet system is a small dry system
with 6 sprinklers to protect a porch area. For us to pipe the main drain of the
dry system we need to core 2 walls to get to the outside of the building, go up
about 15'-0" to the roof of the porch, and for the most part follow the dry
system piping to the end of the porch.
My question is:
If the control valves between the wet system and dry system are tampered &
monitored by the building fire alarm to ensure that they remain open, can we
use the main drain on the wet system to fulfill the main drain test
requirements, and just pipe the drain of the dry system to a floor drain?
Thank you in advance,
