Any 5-Year Testing for Manual Wet Standpipe?

12/4/2024

What is involved in a 5 year inspection/test for a manual wet standpipe?

I see in NFPA 25, 2017 edition that manual wet standpipes are not required to be flow tested or hydrotested when part of the sprinkler system.

So my question again is are there any specific requirements for 5 year testing for manual wet standpipes?

Thank you all!

That is correct to how the 2017 code reads to me.

Otherwise you would need a test pump to conduct a hydrostatic test, flow, or flush test on a manual system. But that's not a specific requirement.

Pipe from the fire dept. connection to the check valve is required to be hydrostatically tested at 150 psi for 2 hours every 5 years in accordance with the 2014 edition onward (13.8.5).

I agree with Pete. NFPA-25, 6.1 et al lists requirements for flow testing, checked up until 2020( 25 handbook). Forward flow only for automatic wet standpipes ( to check the flow and pressure at system flow)
I would also perform the 5 year internal for corrosion listed on the test page.

this is correct
Since inspection of private fire service mains is not practical,
flow tests should be conducted at least every five years. Flow
test results should be compared to previous tests to reveal any
sign of deterioration of the flow and pressure in the system.
Should any deterioration be discovered, a complete investigation to determine the cause should be conducted.
Hydrants should be flushed annually by allowing full flow
for at least one minute. Dry barrel hydrants should drain thoroughly in less than one hour. During this procedure, hydrants
should be inspected for accessibility and operation, and hydrants should be lubricated. Inspection of standpipe systems should begin at the water
supply and continue throughout the entire system on a quarterly
basis. This inspection, as for that of a sprinkler system, should
reveal signs of damage, leaks, corrosion, or any condition that
may impair system operation. Where building occupant hose is
present, the hose should be removed from the rack or reel annually and inspected for evidence of vandalism. The hose should
be free of obstruction and not damaged by mildew or abrasion of
any kind. The hose should be reracked or rereeled in such a way
that folds do not occur in the same position on the hose. Standpipe hose should be removed from the system for hydrostatic
testing at five years and every three years thereafter.
Hose valves should be inspected quarterly to ensure that
the handwheel is not missing or broken, the threads are not
damaged, the valve is not leaking, and the cap is in place. In
cases in which high pressures are present, the valve should be
of the pressure-regulating type. Pressure-regulating hose valves
are generally of two types—pressure reducing, which controls
both static (nonflowing) and residual (flowing) conditions, and
pressure restricting, which controls residual conditions only.
Pressure-regulating devices should be flow tested every five
years to verify that the pressure-reduction setting is correct.
Valves that are not set properly should be reset; valves that are
not adjustable should be replaced.
