Nor, I have only one tank, 120 gal. I guess I will have to drill into the side of the tank near the top. I'm looking for a connection that will have a pickup tube that extends almost to the bottom of the tank. Since it is only 3/4 full, I don't thnik I will have to drain it. Hope to see you this winter.
