When I drained ours using the "T" valve, I observed about a 1/4" stream of clear water, but then again ours has had very little use until this summer.

OK, so the T-drains do give a thin stream.
What bothers me is that there seems to be room below the lower edge of the drain pipe opening to prevent a total drain and to allow some sediments to build up w/ time -- sediments might become inert? I do not know.

Mine is just like the two of you, the stream is small because the inside diameter of the drain tube looks to be around 3/8" and there is no pressure to push the water out. I manage to get about every drop of water out of my fresh tank. I use a leaf blower right after opening the drain on the gravity fill connection. The leaf blower pressurizes the tank and I get a full stream. I have a canvas strap under the tank on the opposite end of the drain. I lift up on that part of the tank to finish the draining. If you use chlorinated city water, you should not have too much problem with bad water in the tank.
