Annual Checks
• Whale® advise that the boat's plumbing system is checked annually for leaks
and obstructions. Also a pump electrics check is advisable.
12. TROUBLE SHOOTING
Pump does not run
No power to pump
Fuse has blown
Check power supply
Attach leads / clean connections
Replace fuse
Blockage in pipework Check pipework for kinks
Pump runs but no
water appears
Pump runs but will not
switch off
Pump cycles on and
off periodically when
all the taps are closed.
Noisy operation
Low flow
Extra delay before
pump switches off
No water getting to pump
Pressure relief valve too low
Water leaking at outlet side of
pump
Water leaking at outlet side of
pump
Check the water tank is not empty. Check
strainer is not blocked. Check all connections
from tank to inlet of pump are secure - any air
leaks will prevent prime
Check water supply level and pressure relief
settings. Ensure these are > 5 bar
Check pipework/fittings for leaks and repair.
Check system drain plugs are closed
Check pipework/fittings for leaks and repair.
Check system drain plugs are closed
Check water supply level and pressure relief
Pressure relief valve set too low
settings. Ensure these are > 5 bar (73 psi)
Water leaking at outlet side of
pump
Check pipework/fittings for leaks and repair.
Check system drain plugs are closed. Pressure
relief valve too low
Pump drawing air See 'no water getting to pump' (above)
Noise created by vibration
Check pump is secured to solid surface. Check
pump body is not in contact with hard surfaces.
Locate away from interfering surfaces. Check
pipework is securely supported
Bore of pipework connection too
Ensure 10mm minimum bore.
small
Power supply to pump
Pipework/connections crushed
due to over tightened jubilee
clips
Check power supply to pump uses correct
gauge wire 2.5mm²/AWG 13) to give full voltage
at pump. Check battery is not discharged
Replace damaged connections
Pump too far from water tank Pump is best situated beside water tank
Water leaking at outlet side of
pump
Pump strainer clogged
Accumulator Tank present on
cold water circuit
Check pipework/fittings for leaks and repair
Check system drain plugs are closed
Remove clear lid, rinse and replace to main
strainer body (retain strainer mesh for lid)
Remove accumulator tank
NOTE- Expansion vessel on hot water circuit will delay pump deactivation
13. WINTERIZING
If water is allowed to freeze in the system, serious damage to the pipe work and pump
may occur. To best avoid this damage, completely drain the water system.
1. Drain the tank either using the pump or a drain valve.
2. Open all the faucets (including drain valve) and allow pump to purge the
water from the system, and then turn the pump off.
