Fresh water tank drain '05 Winnebago 37b

Hello all, we just purchases a new to us 2005 Winnebago 37b. Been going through everything this past week and got to the fresh water system. I noticed that the level indicator says was 2/3 full. I'm sure the dealer put water in to test system and all that. That being said, me being a water guy, I wanted to drain fresh tank and sanitize the system. My question is, where in the heck is the drain valve? Definitely not having any luck finding it. My owners manual shows where it should be but drawing doesn’t match what mine is. Any help would greatly appreciated. Thanks

Seems you are not getting much response here.
I am not familiar with your rig, but must be someone out there with an answer?
Generally (my experience) the drain is very close to the tank. Although I did have one that had the drain under the kitchen sink, mid coach, with the tank in the back. If nothing else you should be able look under the coach and trace back the water lines that come through the floor.
Good luck, wish I had a better answer.

What's the model of your coach--'37B' isn't enough to identify it (for most folks, anyway)?

I'd guess that valve is in the same compartment as the propane tank.

it is usually in the water bay look for a 1.25 in pvc sticking out of the bottom of the coach with a small piece of pex next to it

I have a 2005 Journey 39. The pull to drain on mine is in the compartment in front of the wet bay. Hope this helps.
