I love when events in my life inspire my next DIY post. It seems almost everyday I’m in this position! The latest? Our RV black tank is clogged. It’s been a mounting issue, no pun intended, that has not been resolved properly from the start. So here we are, five flushes later, and still a pile of tissue paper at the bottom of the toilet. Tapping into the wisdom of those more experienced is always a wise move. The overwhelming advice is not to plunge or snake or push or fish around down there (At least, not at first) but to dump some boiling water right down the drain and let it work its magic. We’re two kettles in now and the hubs is about to dump the tank now. I’ll let you know how it turns out! In the meantime, if you’re in a similar scenario, get the full process in the link below.
Better yet, here’s a HUGE tip to prevent your black tank from EVER getting clogged again. First, make sure you’re using the right TP (read our post here about that). Once you’ve got that sorted, after every black tank dump and rinse, add some water back into the tank. Then add some hot water to your toilet boil, and to that, add a scoop of powdered laundry detergent (OR a hefty squirt of liquid dawn) and a half a cup of a water softener like Borax or Calgon. Flush it down! This will keep your water soft and prevent any solids from sticking to the tank! Brilliant!
