It’s a good idea to sterilise your caravan water system a good a few times each season to prevent germs and bacteria growing and to get rid of any build-up of bio film. This includes the taps, pipework, water rollers, water tank and toilet cassette.
In this video, caravanner Dan Trudgian explains how to sterilise your caravan’s fresh water systems using Puriclean.
First of all fill your water carrier with water and add Puriclean. The packaging says you need one teaspoon per four-and-a-half litres of liquid. Give the carrier a good shake and leave to rest for a few minutes. Remove any charcoal water filters from the water system and then attach your water carrier to the caravan as if you’re going to fill up your caravan water system from dry.
Close the showers, taps and drain down taps, then turn on the water pump and open up your taps to let the water solution to go through the system, running it through the hot water tank, cold water tank (if installed) and into all the taps and the shower.
Then shut them off again so the water and Puriclean mix can sit in your system for up to 12 hours.
Once you’ve let the water system rest for a few hours you then need to flush it through. Open all the taps in the caravan so it’s pulling water through them all, not forgetting the shower, until all the solution has been used from the water carrier.
Re-fill the water carrier with fresh water to flush through the system and repeat this process two or three times. By connecting your waste water container you can also clean the waste water pipes and system too.
Test the water by pouring a small glass and smelling it to see if it smells of the cleaning chemicals. If it does run some more fresh water through the system until this smell has gone and have a little sip to check if there’s any taste of chemicals. Continue to put more water through the system if the water tastes acrid.
Finally, drain down your water system and replace the charcoal water filters before replenishing your water supply.
