It's probably a good idea to disenfect the fresh water tank - you don't know what quality of water has been in there or how long it's been sitting there.? ?You can add a small amount of household bleach to superchlorinate the water and disinfect the tank, then drain and flush it with clean water.
Good point Lou. Actually sanitizing the
fresh water tank should be regular annual maintenance, or done after long storage. To sanitize, use plain chlorine bleach (5-6% sodium hypochlorite, no other additives) in the proportions of 3/4 cup to 40 gallons of tank capacity.
1. Drain the tank, and the accumulator tank and heater tank. Dilute the bleach with a gallon of plain water and pour in the water tank.
2. Dilute the bleach in a gallon of water and pour it into the tank.
3. Fill the main tank with water. Run the water pump and open a cold water faucet in the RV to fill the accumlator tank. Then run a hot water faucet to fill the water heater tank. Run all the other faucets in the RV. Top off the main tank.
4. Allow the whole thing to sit for two hours or more then drain the main tank, accumulator tank, and heater tank.
5. Repeat step 3.
And now you should be ready to travel. Some folks add a bit of baking soda to the tank to kill the residual chlorine. I have never found this necessary. Thoroughly draining all tanks seem to do the job.
