Plastic tanks have their advantages, and their disadvantages.
Cecil, you could get 2 pieces of thick plexiglass and bolt them to the bottom of the tank (one outside and one inside) with gaskets between them to seal the bottom of the tank. Then drill a smaller hole thru them for the smaller fitting.
Hmmm... that would work but I already have the fittings for the drain so...
I'm now waiting 24 hr for the rust killer to cure and then will coat that with the epoxy and wait another 24 to 36 hrs! Then I can install the drain and wait another 24 hrs. for the silicone to cure!
It will be a miracle when I finally get this second tank up and running! Oh, and I have to wait for a couple of bulkhead fittings from AES once I order them tomorrow. It seems like it takes at least 4 days to get anything from Florida!
