Where do you install fire department connection of the check valve?
Depends on the set up and run?
I have seen it at the FDC and I have seen it down the line.
Which edition of NFPA 13 is the test based on???
OHHH I am not an engineer, so you can discount my reply if you want
from 2016 NFPA 13
Once again sounds like a bad question, but you do not have the exact wording, so here goes
You can free access to most NFPA standards, you just have to register::
Says if you have a single WET system the alarm valve can be the check valve required.. Which would put it at the main riser.
18.104.22.168.1 FDC shall be on the system side of the water supply Check Valve.
22.214.171.124.1 Check valve shall be installed in each FDC and shall be located in an ACCESSIBLE LOCATION
Ok for now that is all I can find, like I said with out the specific wording best answers.
