Hydrants

Hydrant pump systems are treated separately from this page

WHEN

(frequency of testing)

  • Bi-Annually
  • Annually
  • 5 Yearly

WHAT

(is required to be tested or verified)

  • Signage and block diagrams
  • Free movement of valves
  • Check all Hydrant Landing valves
  • Check auto pump start
  • Installation is compliant to standard
  • All monthly checks AND
  • Flow test
  • Prove water presence at all hydrant valves
  • Verify systems interfaces working
  • Overhaul all landing valves and booster installation
  • Pressure test the system

HOW

(What method is used)

  • Visual checks of all signage
  • Operate all water supply valves (two full turns) and stop valves (eg floor isolation valves)
  • Inspect all landing valves are in good order, handwheel fitted, correct angles and clearances are met and fitted with forged NSW Stortz fittings and blanking caps.
  • Check the booster install for correct signage and block plans, all gauges and valves in good order
  • De-pressurise the system at the most hydraulically disadvantaged point to ensure that the remove start for the pump is operating
  • Perform a test of the hydrant system whilst flowing water at the prescribed rate and measure the residual system pressure is compliant with the AS2419.1 Standard for the building
  • All landing valves cracked to prove the presence of water
  • Verify that the depressurisation of the system triggers appropriate pressure switches and connected alarms or equipment
  • Drain system, replace all landing valves and their immediate coupling. Replace booster points and service isolation valves.
  • Boost the system pressure with a pumping appliance to 1.5 times the working pressure of
    the required design standard
