We took our tt on the first camping trip of the season after de-winterizing earlier last week. Everything works great until it was time to go. I hooked up to the black water tank cleaner, turned on the water and my wife was soon yelling to stop. There was water pouring out from under the bathroom sink, in fact it was a reservoir of water in the bottom. We moped it up and then I had her turn on the water. The black valve in the picture is the culprit as it spewed water like a fountain.
Has anybody had this problem? Do I simply replace the valve or is the cleaning jet clogged in the holding tank?
Thanks, Kevin

I had the same thing happen to me after the first year. It's the vacuum breaker check valve (so nothing comes back out through that line). I am guessing that ours froze as I did not run any antifreeze through this line when winterizing the unit. I was surprised though as it is located very high in the line and I thought that water would just drain out. Anyway, the local dealer replaced it for me, though it did take a while to get the new part.
