Drain Valve

[Amoothart46]

I have a 2020 Thor Quantum class-c motor home, I want to drain my fresh water tank and can’t locate the drain valve. I do have what looks like a location on the bottom of the fresh water tank but there is no valve.
Can anyone help or give me some advise?

I checked behind the rear wheels and every place around the fresh water tank and there is no drain valve. I do have a spot on the bottom of the tank that looks like a small drain valve could be installed, but it’s not a plug I can remove and there are no treads to screw a drain valve in. I also looked on line and saw where on some Thor class c coaches the fresh water drain valve is under the dinette seat. I checked there also no valve under either seat. Now I’m stumped because I think there should be a drain valve some place.

Question, have you gone to Thor's owner resource page and registered your coach? If you haven't suggest you do so. All is needed is your coach VIN. After registering you will have access to build sheets for your particular coach including plumbing drawings. Might help you find what you're looking fort

Our fresh water tank is under the bed and so is the valve to drain it.
