Fill your fresh water tank again with cold water and let the water sit in the tank for about 8 to 12 hours. After the allotted time, turn on all the faucets and water outlets in your RV again and let the water run until the smell of the bleach goes away.
It may be necessary to use some type of sewer hose support to get a good angle from the RV to the campground sewer connection so the tanks drain properly when you empty them. The small valve is for the gray water tank and the large valve is for the black water tank.One golden rule for RV holding tanks is to never dump the black water tank until it is at least two thirds full. You want the tank nearly full so the weight and the gravity will force the contents of the tank to drain properly.our RV has what is referred to as a gray water holding tank and a black water holding tank. The gray water holding tank collects dirty water from the kitchen sink, bathroom sink and shower. The black water holding tank is for the toilet. These tanks terminate into one main outlet used to empty the holding tanks.
