Apply a water pressure of 3.5 - 7.0 bar to the pump and check for leaks. The area causing
the leak should be visible, and can be dismantled and rectified. If no leaks are apparent, the
leakage must lie between the priming valve and the primer. Points to be checked are:
The inlet seal in the primer end cap
The priming valve diaphragm
Thermal Relief Valve (TRV) Test
– if option fitted
With the pump primed, close all discharges. Run the pump, with high pressure selected, at
approximately 2800rpm to permit it to heat up. The TRV should open and discharge water
when the pump temperature is in the order of 45 - 55°C with the standard temperature option
and 70-75
o
C with the high temperature option. Observe the valve discharge, if it is open to
atmosphere, or feel the discharge pipe become warm if it returns to the vehicle tank. Open a
pump discharge valve to permit cool water to enter the pump. The flow from the TRV should
now cease.
