Black tank flush and freezing weather

So we have had some abnormally cold weather along the Gulf Coast of Alabama. We have been periodically checking our MH each morning to make sure that no damage has been done. We've been running our tank heaters and furnace.

This afternoon we decided to use our blank tank flush after we dumped. We discovered a "waterfall" coming out of the outside bathroom wall by the floor. Inside we had flooded the bathroom and it seeped under wall into bedroom.

We had a couple of guys at the park look at it but the hoses/pipes are in the walls and not reachable. We will have to wait until we get home and back to dealer and see what they say about fixing it.

The question is "why did it freeze?" I wouldn't have thought there was water in the lines unless somewhere there is a horizontal stretch. I thought the lines would just go downward?

Anyone else ever had flush line break?

Not knowing how it is plumbed I wouldn't be surprised for water to be in the vacuum breaker and for it to freeze and break.
