COMMON PROBLEMS, POSSIBLE CAUSES & SOLUTIONS
6.
PROBLEM
The piston does not slide easily and there is noise
between the pump tube and the piston.
CAUSE
SOLUTION
There is no lubrication between the pump
tube and the piston sleeve.
Check the piston sleeve. If it is worn-down
replace it and grease it, if not just grease
the edges.
The pump system leaks.
The check valve does not seal correctly
in the seat of the pump tube.
Check the check valve and if necessary
replace the seal. Lubricate before
reassembling.
The water pump is pressurized but there is no flow when
pressing the shut-off handle.
The pump tube is not tight enough.
Loosen the hose clamp and check if the hose
or the tank outlet are clogged and if so,
proceed to unclog them with pressurized air
or water.
Although the water pump is being pumped vigorously it
does not build pressure.
The hose is clogged.
Tighten the tube and grease the o-ring.
Always store the water tank clean and empty in a dry place protected from the sun.
