Is this the main drain for fresh water tank?

I'm sanitizing my fresh water tank and now need to drain it. Is this the drain? This picture is under the coach on the street side just aft of the driver's door.

FYI, open slowly. If water not clear, tighten back up. DAMHIK

That's exactly what I did I used Teflon tape in reinstalling the plug. I hope that's acceptable. Thanks!

I found that with repeated removal of the drain, the soft threads began to wear, so I replaced the plug with a 90 degree pvc fitting that threaded to the tank, and then attached a low profile valve. It hangs down about an 1" from the tank. Now, I just turn the valve. Don't later Interstates now have valves as well?

The cost-about 5 bucks.

That's a great idea! Can you post a picture? This should be on the Interstate mod thread

Nope. But the 2013s seem to have a different tank than the 2012s. Mine has the drain valve flush with the bottom of the tank, without the sump pictured for the 2013 model shown in the original post.

Last time I had to drain the water, I thought the drain valve on mine was the same size as an oil pan drain plug, just made of PVC. If so, then they make valves to replace the drain plug on an oil pan, and I thought of buying one. But then again, I don't have to drain the tank very often, and decided it wouldn't be worth the expense. Especially since the valve would stick down far enough that it could snag on something and get knocked open, knocked loose, or knocked off.
