Black Tank June 18, 2025, 04:38:30 pm Time to resurrect the old black tank cleaning issue. Almost as controversial as tire pressure! Anyhow, I dropped the black tank a couple of days ago and took a look inside. I've had this rig for about three years and never rinsed the tank nor added any chemicals. Just dumped, poured in some water and a little Calgon & Dawn. Clean as a whistle. Check it out!jor 3 Likes

The black tank is prone to building pyramids directly under the toilet.The one black tank I dropped had its vent pipe punched in after the roof vent was hit by a falling tree branch. I had to cut the toilet flange off to get it out. The top of the tank was badly cracked and required a bit of repair work.Three Island Camp, Glenn's Ferry, IDLarry 3 Likes
