Using Flowmeters for Fire Pumps

9/14/2017

We have never used a flowmeter with a bypass to conduct annual fire pump tests, but have been asked to explore the option in an effort to save water. Using a flowmeter and test bypass for a fire pump, would a test header still be required? For those in areas with strong water conservation, do you have any recommendations on things to look out for?

Every third year the annual test must be conducted using hose streams. Recommend keeping the test header.

NFPA 25, 2017 Edition
8.3.3.6 The annual test shall be conducted as follows:
(1) The arrangement described in 8.3.3.6.1 or 8.3.3.6.2 shall be used at a minimum of every
third year.
(2)* The arrangement described in 8.3.3.6.3 shall be permitted to be used two out of every
three years.

If the pump feeds yard hydrants then these could be used in lieu of a test header to perform the required flow test.
