Draining tanks on Thor ACE 27.2
Good day,
We have a new Thor Ace, that has a hose hookup to clean out the black water tank. I believe I followed all the instructions (which are virtually non-existent in the owner's manual) by hooking up a hose to drain the tank. The valves are in the correct position, and the black water tank took on about 30 gallons of water, yet nothing comes out of the sewer hose? So, where did the water go? Any ideas? Thank you. JE
