You need to be very careful about sanitation. Remember black tank contains human waste. You want abaolutely NOTHING that will be used for human consumption coming in contact with the waste. That means hoses for ONLY drinking water and other hoses ONLY for flushing black or sewage lines. When your done camping, it is a good idea to rinse the sewer hose before putting it away. You will see on the forums many folks that never use the toilet. And if they do TP goes in the garbage. Most of us do. Again the key is proper TP and,lots of water, and never dump until the tank is nearly full.
