I then run the built in sprayer to really clear it out, opening and closing the valve a few times. I purchased a see through elbow that hooks onto to sewer hose. This way I can keep the sprayer running until I see clear water coming out of the black tank. Once done, I shut the valves, let the black tank fill with fresh water (a few gallons) and add fresh Calgon and Detergent. Just before we take off, I sometimes dump ice cubes down the toilet. They slosh around down in the tank while driving down the road, cleaning the tank even more. This is our 2nd year with this RV and no odor.
Hi Mike and Rose, and welcome to the Jayco Owners Forum! You pretty much described what we do when we pull out of a campsite. Except we haven't added any kind of chemicals. But we have done the ice cubes per suggestion from another rv forum. Anyhow, glad to have you here. 2nd year... where all have ya been; do you stay local or travel cross country?
