Placement low point drains on 2005 Mtn Aire gas

Mine is a diesel but the low point is in the wash bay. There is a white "tray" on the bottom of the bay and along the back edge there is a small cut out. Just inside there on the floor is the low point valve. Not sure if it's the same for yours.
I usually use Teflon tape when I put my anode rod back in to help remove it, but if it's been in there a while it may have corroded together with the outer screw shell. May have to drill out the old one.
