Since I fucked up the last post on RV Tank Cleaning, I’ll try to correct that here and now. After 1 1/2 years of not using the RV I had to clean and disinfect the water tanks thoroughly and, while thinking I bought the product I used before, I actually got a different one. This was a little bit more complicated than the one used before, so I I’ll describe here how it worked:
Cleaning and Disinfecting
First of all, you have to “activate” this stuff by adding component A to component B (aka drop the tablet into the liquid) and let it sit to react for three hours.
Drain the tank, add 15 liters of water and mix 5 liters of water with half of the activated solution. Add that in too. Open all taps (dont forget the toilet flush, and – if you have – use the “hot” position, so the heating boiler will be flushed as well) and let flow until cleaning solution runs through. Let about 10 liters flow through your pipes, so everything gets into contact with the detergent.
Fill your tank halfway with about 50 liters of water and add the rest of the cleaning solution. Now let that sit for 4 up to 24 hours. Open all taps again and let all the content of the tank run through. If you want, you can keep the solution in your waste water tank for another couple of hours to disinfect that one, too. Rinse the whole system with clear water to remove any detergent residue.
Filling up and Conserving
You want to conserve your supply of fresh water so it doesn’t spoil or contaminate by bacteria. There are a lot of products on the market that help you to insure clean water, but most of them rely on silver ions (which seem to be gods revenge for bacteria etc.).
I use a pretty much standard treatment called “Certisil” for conservation (available e.g. here or here). It’s a well known product for camping, RV-ing or yachting, etc. I use this brand but there are several products on the market that do the same. Just add the recommended amount of agent to your tank and you’re done for several weeks.
