• Operate water flow alarm switches of 10 mm test valve to simulate fire. Weekly rotation must cover all on quarterly basis.

• All pressure switch for its internal mechanism, secured mounting and proper functioning. Pressure flow for water supply should also be checked.

• Electric pump: upon simulation of fire condition, should start operating in 30 sec without any vibration or noise. Special attention should be paid to pressure, gland operation, alarms, priming water etc.
• Compression–ignition engine driven pumps: run for 10 min to check for belt drives, leaks, battery position, charger, speed and sign of ‘out of balance’.
