I am going to install a Tornado Tank flusher in my 29BHS, one question it comes with a vacuum breaker would it better to install it permanently directly on the tank flusher rather than on the hose each you need to flush?
When i installed mine it was a upgrade from my factory installed one. I installed in existing hole with a few mods. I routed the hose up above tank and then brought the hose over to the drain valves and mounted the bracket. This made for easier access to use the flush ( than on opposite side of camper originally) with the vacuum breaker installed on flush you will be able to drain the hose so no fear of freezing when that time comes back around.
Good luck
