The RV toilet is very badly clogged with stool. Should have started with this product. For the first time in a couple weeks after about three days stepped on the flush the liquid drained. The black tank had stopped draining. This time it drained quite a bit. But it is again not draining when I flush. I will order another bottle and meanwhile I will keep trying snake. The snake I believe helped open it up so clear could work.
