Pre-Season Water System Preparation
Do you own a Caravan or Motorhome?
Follow this guide to preparing your leisure vehicle for the new season
Why should I follow this Guide?
Over the winter months bacteria can grow in your water system.
Particles of minerals and dirt gather in joins and any
undrained areas.
To check the system hasn’t suffered any frost damage over
the winter and floods your van.
After following this guide, change your water filter
If you have a Whale AquaSmart system, change your
Whale WF3000 Water Filter. If you have an in line filter in
your plumbing system, Whale recommend you use
WF1230 Aquasource Water Filter.
Close all drain valves in your van’s water system.
Re-attach your shower head.
Ensure all taps and showers are positioned over sinks and drains.
Check condition of leisure battery, if it is below 12V please connect to mains electricity supply.
C’VAN Rinse out fresh and waste water tanks with water, add a non-caustic cleaning and purifying agent
M’HOME Add a non-caustic cleaning and purifying agent to the fresh water tank.
Completely fill your fresh water tank with tap water.
Leave the hot tap that is furthest away from the water heater fully open, close all remaining taps and showers.
Turn on isolation switch for water pump, normally found on the control panel or in a menu within the control panel’s software.
You should hear the pump running or the pressure coming from the open hot tap.
Water will pop and splash as it comes from the hot tap, it will take some time for a flow of water to arrive as
the water heater needs to fill up first.
Once an even flow is achieved, work back towards the water heater, opening the next furthest away hot tap until all
have been opened and there is a smooth water flow.
The next stage is to close all hot water taps and open the cold water taps in the same order as the hot taps,
beginning at the furthest away cold tap.
When an even flow is achieved through all the taps in your van close all the taps. The pump should turn off (after a few
seconds if it is a pressurised system).
Remain in your van after the pump has stopped and inspect all the taps and shower heads for leaks. You may need to
dry them down first to spot any leaks). If there is access to the underside of the taps check for water leaks.
Have you found a water leak?
While checking the taps and showers
you may hear the pump turn on and
off a few times. If you hear this, turn
on and off all the taps for 10 seconds
individually to remove any trapped air
from the system.
If there is a water leak coming from the connections on the underside of the tap try to
push them home or tighten them with a spanner depending on the connections.
If the leak originates from a crack or an unknown source check the rest of the taps
and showers before turning off the water pump.
Then drain the water system as the water pressure will continue to escape through the leak
and will cause water damage to your van. Contact your local dealer to rectify the leak(s).
If the pump continues to run intermittently for short bursts this can indicate a leak as pressure is being lost,
Follow all the water pipes and check if there is any water leaking from joints or if a pipe is burst.
Should you find a leak at a joint, tighten the joint or push the pipe fully into the Quickfit fitting to dry up the water and
wait to see if the problem persists
If you find a burst pipe or damaged tap/shower we recommend that you contact your nearest Caravan/Motorhome dealer.
After the cleaning agent has remained in the system for the required time, purge the system by running 2 or 3
full tanks of water through the system using all taps and showers in the mixed position.
Change your filter.
If you have successfully carried out this guide
please check your water heater is functioning
correctly, to do this please follow the
manufacturers instructions.
Enjoy the new season.
