WATER SYSTEM
Before operating the water system, check
the following items visually for signs of
leakage:
Freshwater tank
Check condition. Fill tank and check for
leaks. Check external filler and filler pipe to
tank. Check venting. Check presence and
condition of filler cap.
Wastewater tank
Check that the drain tap is clear and
working properly. Make sure that the drain
hose is present and in good condition.
Pump filter
When applicable, remove the filter, clean
and replace. Check the in-line pump for
security of fixing and condition. Check that
the pump inlets and outlets are clear and
not obstructed. Check security of fixing and
condition of delivery hose and electric cable.
System check
Operate the pump and check all piping for
leaks. Operate all taps and shower. If a hot
water system is fitted, it can be checked for
leaks using cold water.
Please note: Aerated water from a tap could
be caused by a leak on the suction side of
the pump.
Wastewater system
Allow water to run through drain pipes and
check for leaks and satisfactory draining
from sinks etc.
Couplings and fluids
Avoid confusion by making sure proper
markings are used. Blue for fresh water and
red for waste water. Check that the filler
positions are correctly designated 'petrol',
'diesel' and 'water' as appropriate.
ELECTRICAL SYSTEM
Extra low voltage 12v (excluding vehicle electrics):
• Batteries: Check the condition of any battery,
including connections, wire, fuses and relays
connected with domestic electrics.
• Wiring: Examine all visible wiring for damage or
wear. Check that all connections are safe.
• Fuses and holders: Check that all fuses and fuse
holders protecting the domestic electrics are
satisfactory. Check that the fuse ratings are
compatible with the appliance being protected.
• Appliances: Inspect all appliances for signs of
damage, overheating or wear. Check the security
of the fixings. Test the operation of each appliance.
• Mains system 230v: Inspection and certification
of the 230v system should only be carried out by a
suitably qualified electrician.
