11.8.3 Strainer
If slow delivery is accompanied by an increase in the noise of the pump, this usually indicates
that the fault is on the suction side: possibly a partial blockage causing the pump to be "starved"
(probably a clogged strainer). To correct this problem refer to Figure 11.4 and perform the following
procedure:
1
Remove the four screws securing the strainer cap, and withdraw the cap complete with filter
element.
2
Exercising care, clean away any sediment that may have collected or spilled around the
strainer opening.
3
Thoroughly wash the strainer element in gasoline and use clean low-pressure air, to remove
dust and lint.
4
Check the gasket and, if it is serviceable, reinstall it together with the strainer cap and filter
element.
5
Test the dispenser for satisfactory operation, checking for leaks around the strainer cap.
6
If the process of cleaning the strainer element does not result in an improvement in the speed
of delivery, inspect the underground installation for obstructions.
