We just got back from a trip last week. We won’t be going on another trip until August. We flushed out the black and grey tanks and filled the fresh water tank, and water heater. Then added 2 cups of bleach to the fresh tank. Let it sit for 2 days, then ran the treated water though all of the faucets and showers. Didn’t run the toilet…didn’t want bleach to mix with the chemicals. Then drained the fresh water tank and left it empty. I put about 2 gallons of fresh water in the toilet with some chemicals. Will fill and drain the fresh tank and water heater once more before we leave.
Have followed the same procedure for the past 5 years with no issues.
