2017 Thor Quantum Freshwater tank drain

[Bildebhunt]

I just bought a used 2017 Thor Quantum. I don’t know when the fresh water tank was last sanitized and would like to do it. Can anyone tell me how to drain the fresh water tank without having to use the water pump? I have searched for a freshwater tank specific drain but can’t find one. It looks to me like the only way to empty it is through the gray tank, but I feel like I must be missing something. Thanks!

It's usually in the same compartment as your fresh water tank. Mine (FW 28A) is under the bed in the back under a lid that had to be unscrewed. I put in an access panel to make it easier to use.

It most certainly will be at the base of the fresh water tank. Either in a compartment with the tank or underneath the tank (on the outside). Occasionally Thor puts a little white spigot on the outside wall adjacent to the tank. If you never do find it just open the low point drains and let the water pump drain it. It will be as fast or faster than a gravity drain.

Some are easier to find, than others.

Ugh! That looks like a lot of work, thanks!
