How to clean a water tank.

Peter_n_Margaret · Guru

Fit a twin 10" household filter system - a 5um sediment filter followed by a 0.5um carbon/silver filter, after the pump and before the taps.
Add some chlorine each and every time you add water to the tank.
Your water will be safe and sweet forever. No need to ever "clean" the tank.
Cheers,
Peter

Hi Aussiefolks

I just empty the tanks, just before I start a road trip and then refill

I also refill using a B.E.S.T. filter, which has charcoal, and silver, to stop any bacteria going in
I also do not rely on the tank water for drinking, but use bottle water, as a safeguard from tummy problems, while on a road trip

I am led to believe that you can purchase stuff to clean the water tank/s, from most camping or caravan shops

I am sure that others will come along, and tell you how they clean their water tanks

Leaving the chlorine in the water will continue the biological protection it provides, just as it does in your household water supply.
Bugs WILL grow in a dark tank especially in warmer conditions.
Chlorine in the water breaks down naturally quite quickly particularly in the warm conditions in an RV tank and that is why it is necessary to replace it regularly.
As the water passes through a carbon filter just before the taps, any remaining chlorine is removed by the carbon.

Yes, liquid sodium hypochlorite.

Quantity depends on the concentration. Swimming pool chlorine is about 12% and the minimum rate is 5ml/100L. Household bleach is about 6%, so you need double. We typically use about double the above rates and more if the water is suspect and more regularly in warmer weather.

Cheers,

Peter
