Toilet won't drain
You guys helped me out before, and i need help again. I have a Cedar Creek Hathaway 38 FBD, with 2 toilets. The black tank is drained, but the down stairs toilet will not empty. I've used the black tank flush, back flowed the gray tanks, ran a snake down the toilet, used a high dollar plunger and even filled the black tank up and drained again, but nothing is working. I only have 1 black tank drain valve, so I'm assuming i only have the one black tank, but i have the factory multi tank read out, and a secondary level monitor. Any ideas?
