Hi Denis,

        Sorry to hear about your water issues. 

        I also use my water supply in the van for drinking water. 

        I believe I follow the recommendations given me from this list. 

        Each fall I drain the tank and dry as completely as possible.

In the spring I let out any condensation that built up and since.

I then fill the tank and add a cup of bleach.  I then run the water into the sink to pull the bleach through the lines.
I then have the van driven to splash the water around a bit.
I then drain and rinse again.
run through the lines 

And I then use the water for the season. 

No problems for me in three years.

. What is a correct procedure to clean the onboard water supply to the sink faucet which I use as drinking water also. I came down with something as we traveled through Ontario camping. I think I did this wrong. In fact I may not have done anything with the water only filling it up trying to get out of town, ugh!
Had to cut our planned trip short. 
Is there a water filter that's recommended to use while using a camp ground water supply?
