I purchased my new fresh water tank before I knew exactly how my plumbing would be configured, so I thought I was being smart by ordering a blank tank. I figured I'd add the fittings when I was ready. The problem, I'm realizing now, is that my tank is polyethylene and adding fittings isn't going to be as easy as I thought it would be. The only option I can find is the Todd Fitting Relocation Kit. Is this what I should use?
It seems like no matter where I put the hole for the drain, the lip of the fitting inside the tank will prevent the last 1/2" of water from draining out of the tank. Is there a trick I could use to maximize the amount of water that can drain? I'm thinking about building a support platform underneath the tank that's slightly tilted so that all the water would collect in one corner. Is this a good idea, or would it unduly stress the tank if it's not level?

I don't recognize the Todd method, but do know that most poly tank fittings must be "heat spun" in. The spin actually heat welds the fitting in place. 1/2 inch in the bottom of the tank won't matter. It's the lines and fittings that need to be empty over the winter. A tilt isn't a bad idea; won't take much...
