> Bill, this is fantastic -- thanks!  We just bought a Westy with a missing drain plug -- I thought it would be easy to order a new one but was surprised to not be finding any online.  Ours currently has a cork in it, which actually works reasonably well, but I think it's nearing the end of its usable life, and I don't know where the previous owner found a cork that size.  When I drained the tank, there was also an expanding metal plug that had apparently been abandoned in the tank as well.  :)
