I have a false bottom over a bottom drain now, but when I had a cooler with a false bottom, I had to use a piece of tubing to siphon out my wort because otherwise I'd "lose" about 3 quarts of wort.

Oxygenation of wort doesn't cause off flavors. There's an entire step in the process dedicated to infusing as much O2 into the wort as possible. You only need to worry about oxygen once your wort has turned into beer.

Ahh, I am a tipping guy myself. Perhaps I'll try this mystical tubing method.

You can buy high temperature vinyl tubing at home depot (thicker wall than what you're using now, braided reinforcement) for pretty cheap. It won't collapse like your current tube. Also put something under your mash tun to tilt it (piece of 2x4) before you start running off to minimize the wort left behind. The softer angle will help with the tubing kinking.

Bubbles/liquid-air separation will always form at lower flows (during the beginning of the vorlauf), but go away when the valve is wider open.

Yooper, I'm unclear how you use the tube to "siphon"? I just give up on those 3 qts of wort usually, but I know there's some good fermentables in there.

Well, you put the tube at the bottom of the vessel you're going to. Once you get below the level of the diptube in your MLT, if you have a tube going to the FB from the ball valve, and don't break siphon, you can "suck out" all of the wort under your false bottom by the siphon. Try it!

Edit: I reread. It IS a cool new brewing trick. Tks!

1. What kind of tubing is that?

and 2. You have nothing to worry about oxygen wise. No clamp needed, i promise.

This thread helped me prevent cavitation issues with my pump in my brew tonight. Probst!
