Thanks you kind Sir.IMO---All MES water pans should be left in place, covered with foil, but no liquids should be added to them.
I have not put any liquid in my Water Pans for 8 years. Adding liquids does nothing good.
The only full length pan there is would be the stupid slanted drip pan in the Gen #2, which like I said should be best to remove & do what I said in Post #18 above.
