2012 Thor Ace 29.1 fresh water tank drain valve

I am new to the forum - I recently purchased a 2012 Thor Ace 29.1 and I am having difficulty locating the fresh water tank drain valve. It had been winterized before I purchased it. As I now prep for making our first trip - when filling fresh water tank it just keeps draining. Manual talks about a fresh water tank drain valve but does not describe its location. Tank access is under the bed - but can find not a valve to shut the drain. Any help would be appreciated. Thanks

You're looking in the right area to start. If you don't see a drain line/valve under the bed (it could be horizontal), then look in the water pump area. There may be a combined low point/tank drain on the suction side of the pump. One clue would be where is the water draining location when you add water to the FW tank?

Welcome to the forum. You might also try looking in the wet bay near the input to the water filter. Take your hand and slide it along the input pex pipe away from the water filter input side (not the output side that connects to the water pump. You should be able to feel/find the fresh water tank valve somewhere along that water line pipe in the rear of the wet bay. Not very convenient but accessible.
