Hydrostatic/Leak Test for Sprinkler Relocations?

8/22/2019

Does a hydrostatic test need to be performed for a project that just has relocated sprinklers, or just a leakage test subject to working pressure?

I'm having trouble finding where NFPA 13 gives guidance on this. Any help is appreciated.

Check out NFPA 13 (2013 Edition) Section 25.2.1 and NFPA 25 (2014 Edition) Table 5.5.1.

NPFA has testing guidelines but I would definitely check with the AHJ to see what they want, because this varies a lot by location.

In Section 25.2.1 of the 2016 Edition of NFPA 13 as well, there are references to required hydrostatic tests of modified existing systems affecting 20 or less sprinklers, and modifications that cannot be isolated, such as relocated drops (25.2.1.4), which require testing at working pressure. 20 or more heads require 200 psi for 2 hours.

I would have to agree with NK.

Check with the AHJ. In one city I can relocate up to 20 heads with out a Hydro test. In the next city over if i even think about moving a head I'll need to pressurize the entire system.
