TESTER HOOK-UP NO. 2
Pump Flow Test, also known as Pump Efficiency
Connect the tester in series between the pump outlet and control valve. With the valve in the neutral (off)
position, we can measure the pump output to ensure that the working pressure and flow is adequate to drive
the motor at the desired speed. Use extreme caution when using this procedure; there is no relief valve,
between the pump and the restrictor valve when tested in this manner. Be absolutely sure the flow meter is
open when starting the engine. If the reading from Test Hook Up No. 1 is below specification, and for this
test, Hook Up 2, the reading is ok, we can then suspect the relief valve or control valve as being the problem.
