Worked wonders for me.
You may have solved my problem for me. I was about to ask what is the best way to drain and rinse out the black water tank on my 213QBW
? I drain it and put a hose down through the commode and run it until the hose runs clear, but I'm not sure that's really getting rid of everything.
Would what you suggest above, putting something in the tank and letting it slosh around until I get to a dump site work? I would think something more cleansing than Calgon, unless it does more than I'm aware of, would be.
I am very open to any method of cleaning the black water tank out. If anyone has any suggestions I would like to hear them. Thanks
