Couple observations:
Your pump suction Boss should have a small strainer in it.
On the bottom of the tank you may have a 2" drain about 1/3 of the way away from the plumbing connections. It protrudes such that it tilts the tank so it can't be fully drained, (plus holds a couple of precious gallons) ....................
Del, my tank had a Styrofoam sheet under the tank between it and the tub/tray it sits in with a cut out to accommodate the protruding drain plug. It therefore sits flat in the tub and drains fine. One end and the sides of the tub/tray are also insulated with Styrofoam and it is obvious that the Styrofoam lined tray provides freeze protection. The tub and the cavity around the tank also has a hot air duct which supplies warm air to it when the furnace is running. I am wondering if someone removed the Styrofoam sheet in yours once upon a time?

Hey Alan:
Should have mentioned that mine was insulated with styrofoam also but without the cut out for the 2" drain. It was a sloppy job by someone. A Previous owner mentioned a freezing issue so maybe the tank was dropped.
The drain line for the tank had a kink so it only drained a drop at a time. I just capped it off and will drain with the 2" if needs be.
The two valves for hot and cold plumbing drains are the ones I relocated near the water pump.
Glad you got a new tank and have fun get'n it all back together.
