Camper City in Victoria, which I have not liked, had the part that I needed, water module assembly, so I had to get it there. Fixed and not one molecule of water coming out of the back. Now to work on the 8-year-old pyramid under the toilet. Right now, it's too windy and cold to deal with this. Yes, we have a cold front underway as far south as the 29th parallel. Will get down to 38 degrees at night for two nights. I was lucky to get this fixed. While waiting to have a dealer located, I seriously thought of putting in a threaded cap on the fitting where the toilet valve attaches to the water line behind the toilet and instead use the shower head as the source of water, so that I can run the toilet and fill the bowl. Now, I don't have to go that route.
I bought some granulated waste digester, though I have a full bottle of the chemical liquid that came with the trailer (would you believe that not only was that bottle opened and the original seal not peeled off and thrown away like it was supposed to be, they didn't even USE IT!). I will be using it to break the stuff down religiously from now on.
I think I know what happened when I was on a ranch while staying in a partially functional fifth wheel trailer (overhead AC went out and stove had a leak, and 5 months after I left, the quest water line busted inside the wall behind the shower/bathtub - from what she said, it was a MESS to clean up); apparently (since I had forgotten how RV black tanks are supposed to work), we had left the black tank valve open ALL THE TIME, thinking that waste was going into the septic tank the whole time, and every once in a while, I would test the black tank read out, and it would indicate it was getting fuller and fuller, meanwhile, flush water would drop down into the hole and splash back up and I would remember to stand out of its path as it shot straight up and straight back down. I suppose she figured out what was going on some time after I left.
