Sunseeker 3010DS Blackwater Tank Flushing System

My blackwater tank flushing system seems to be a casualty of recent cold weather in Texas because instead of flushing the tank it flooded my bathroom. From where do I access it for repairs? Is it behind the bedroom dresser drawers? Any suggestion will be appreciated.

Can someone tell me how to access the blackwater tank flushing system in a Sunseeker 3010DS? Is it behind the bedroom dresser drawers?

Does it have the fresh water flush? A hose connection to flush tank?

You're looking for a "vacuum breaker" mounted about 5-6 feet above the floor maybe in a closet or void. There will be two pex piping runs to it each of 1/2" size. The piping is from the hose connection to the bottom of the valve and the outlet leads to the side of the tank. I prevents flow from the tank to the fresh water system by not allowing the water to flow "backwards". If the seating disc gets stuck the supply water will flood the space its in. You know the approx. location already, where all the water came from. Easy to change or repair.

So does the black tank flusher have to be winterized??? I never gave it a thought.

But to your question, as someone else asked, did you have your dump valve open? Is it blocked up?

Yes it should, at least low compressed air through it, some push anti-freeze. It supposed to self drain but I don't take a chance.

The flush is designed to be gravity flow after flush.
