I'll probably purchase 2 of the 25-50 PSI versions you mentioned above since you can adjust them to 2-3PSI. It appears two of my other ones I got from grainger for $30 a piece are shot.

Thanks for the tip.

How are people using fining agents like gelatin when fermenting under pressure? Are you putting the gelatin in your serving kegs and just accepting that your first few draws will pull the crap that gelatin settles out?

Default Word of caution on the 25-50 psi version.

At the lower end it takes a gentle hand to adjust it just right, and don't over-tighten the valve or you will cut into the soft pad, making it harder to adjust later.

Good luck with these, I think you will like them once you get used to them.

I have been thinking about using geletin for some of my less clear beers but have thought myself out of it again. I'd be interested in the reply as well.

Haven't read the whole thread but has anyone cut the gas tube shorter. You could probably cut close to 3/4" off and still use it as normal. Might save a little bit of blow off

I'm interested to try this method in Corny kegs.
How do you take gravity reading?

I assume that you can attach picnic tap on liquid side, but since it goes to bottom it will mostly pick yeast and trub material...

diS, Yes, that's how you do it. I first draw a little out into a jar (big one), then draw my sample into a small jar. You need to de-gas the sample by putting a lid on it and shaking it. I usually wait several hours, as I am not in a hurry.

I leave a block of wood (or a wedge would work) under the side of the Corny where the long dip tube is (my fermenting Corny has the tube come down the side, not the center). That gets the tube out of the worst of the muck. I still have to do a couple pulls on the Picnic Tap to clear things, but it's usually a lot less than when I leave the Corny flat. Results vary by the type of yeast and how much trub is in there, of course.

Invest in a refractometer. You still get trub/yeast but you need only a few drops, and you don' have to wait for temp or CO2. Also you won't know how you did without one on the brew side once you start using it. I have been loving mine.

love mine too.. there are plenty of calcs out there that will adjust for fermented beer as well.

I don't like refractometer for FG reading since it always needs different correction factor (at least my cheap e-bay refractometer).
I'll try with picnic tap and degassing method, thanks.

Does pressure relief valve has to be adjustable?
Can I mount relief valve with fixed pressure (eg 30 psi)?

I am thinking to put blow off tube for 1st 2 or 3 days so pressure don't impact yeast growth, and then put pressure relief valve for carbonation?
