Hi all! This weekend when draining the black tank, it was very slow. I've been wondering if the outer casing on the drop-ins isn't dissolving and clogging the drain pipes. I went ahead and bought the liquid form, but wanted to ask if any of you have experienced this and what you did to solve it. In case you're wondering, we limit the number of times we go #2 and only use toilet paper designed for RV/boat septic systems.
Slow to drain......
Check that the roof top tank vent line is clear.
Birds nest, debris even falling down so end of line is farther down into tank will cause slow draining issues
Vent line MUST be clear for tank to drain properly
Quick and easy check to see if vent is your issue
Trying draining tank...then Flush/hold toilet valve open and see if tank drains faster. Toilet open provides venting
If YES then tank vent line is obstructed/blocked
Run hose down vent line and blast it clear
If still drains slow with toilet open then tank dump valve may NOT be opening fully or you have a blockage at tank outlet.
As for chemicals......POO
Dihydrogen Monoxide is the ONLY chemical I use period for 40 years.
RV waste tanks are 'holding tanks' not processing units.
Fill dump repeat.
And if you smell it then you have a vapor barrier issue...find/fix that and no smells
