Troubleshooting
5.4.1
Vibration induced by road conditions can cause plumbing to loosen. In the event
of a leak first check for any system components that are loose. Most leaks can be
resolved by simply tightening the hardware.
5.4.2 Pump Will Not Start/Blows Circuit- Check:
i.
Electrical connections, fuse or breaker, main switch, and earth connection.
ii.
Is the motor hot? If it is the thermal breaker may have triggered; it may
reset when cool (This is an automatic, not manual service).
iii.
Is voltage present at the switch? Try to bypass the pressure switch. Does
the pump operate, if it does it indicates faulty switch.
iv.
Charging system for correct voltage (± 10%) and good earth.
v.
For an open or grounded circuit, or motor; or improperly sized wire.
vi.
For seized or locked diaphragm assembly (water frozen?).
5.4.3 Will Not Prime/Splutters - (No discharge/motor runs) - Check:
i.
Is the filter clogged with debris?
ii.
Is there water in the tank, or, has air collected in the hot water heater?
iii.
Is the inlet pipework/plumbing sucking in air at plumbing/connections?
iv.
Is inlet/outlet plumbing severely restricted or kinked?
v.
Proper voltage with the pump operating (± 10%).
vi.
For debris in pump inlet/outlet valves or swollen/dry valves.
vii.
Pump housing for cracks or loose drive assembly screws.
5.4.4 Pump Will Not Shut-Off/Runs When Tap is Closed - Check:
i.
Output side (pressure) plumbing for leaks.
ii.
For air trapped in outlet side or pump head.
iii.
For correct voltage to pump (± 10%).
iv.
For loose drive assembly or pump head screws.
v.
Are the valves or internal check valve held open by debris or is the rubber
swollen?
vi.
Pressure switch operation/adjustment, refer also to shut-off adjustment
instruments for the switch.
5.4.5 Noisy Or Rough Operation- Check:
i.
For plumbing which may have vibrated loose.
ii.
Is the pump plumbed with rigid pipe causing noise to transmit?
iii.
Does the mounting surface multiply noise (flexible)?
iv.
For mounting feet that are loose or too tightly compressed.
v.
For loose pump head to motor screws (3 long screws).
vi.
With the pump head removed. Is noise from motor or pump head?
