Full Flow Test Required for Manual Standpipes?

5/8/2019

NFPA 14 requires standpipes to be full flow tested for the acceptance testing.

Automatic standpipes are fairly straightforward to test, but how have you seen this applied for manual standpipes in mid-rise buildings?

Is this a worthwhile test that will uncover design/installation flaws?

Also, is there any compromised method to meet this requirement?

Yes, it is done all the time across the country. McKinney, TX FD has a great SOP. https://www.mckinneytexas.org/DocumentCenter/View/855/2010-05---Standpipes-Flow-Test-Procedure?bidId=

Yes, testing of Manual Wet Stanpipes is still required. The method provided by Kieth looks solid....if you have fire department support. Our jurisdiction does not provide this support, so we have to hire someone with a portable, trailer mounted fire pump.

I live in San Diego Ca. and want to hard pipe the sprinkler ssytem drain down pipe into the 6" sewer via a closed system.
My inspector can't tell why I can't just I can't and need to build a 4" stand pipe with a wet trap. This will use a lot of water throughout the years just to keep the trap wet and will only be used once a year.
I would welcome any commits from anyone.
thanks
