Yep, gas is gas no matter the direction it is flowing. The gauge would not interfere with incoming CO2 and would even be neat to have right there in the keg during transfer.

spundify!

now i just hope if fits in my little fridge with the gauge on so i can cool it and have it reach cold equilibrium before i have to remove that gauge! minor design oversight but never mind

That is a slick little sounding valve. I built mine along with the pressure gauge onto a gas disconnect. It sets it off nearly horizontal. If you run out of headroom that's another option. It also is immediately swappable to another keg if needed.

All great spunding valves guys!

Hi,
I tried to read through most of this...not in order, sorry

I am wanting to try this process....
If I planned to brew up about, say 9 gallons in the fermenter, left some trub in the boil kettle and put 4.25 gallons each corny would that work?

How high does Krausen get in a corny with out fermcap?

thanks Kevin

It depends significantly on yeast strain, fermentation temperature, and OG. I fill up to the weld line, which is right around 5 gallons, and end up only with a few ounces of blow off, but that's with Fermcap.

The best thing to do is to build a water trap using a water-filter housing, and to set that up between your corny and your spunding valve. That way, you catch the blow-off without clogging your valve. Saves a lot of headache

Can you post a pic of the water trap set up?

I like that idea better than using a blowoff set up.

This isn't a great pic, but you can get the notion in this post:

To me the easiest way, if you have the room in your fermenting area, is to use a third keg, connect from the gas out of both main kegs to the third keg liquid using a Y connection or could do it in series as well. Then fit your pressure regulator to the gas outlet of your third keg. Then you don't have to worry about overflow and you could do the whole 10+ gallons. Hope this helps, it has been mentioned before, and it works for me! One precaution I have found with this is that you don't want much trub or esp. dry hopping as it can/will in the case of the dry hopping clog the small openings in your connections quite easily if you have much in the way of hop solids. Keep an eye on the system to ensure all is flowing well by using clear hoses.

I can't wait to use my new cropper trap spunding valve this weekend! I bought a water filter housing especially for this application. I hope it works first to catch the stuff that normally gunned up my SV, and secondly to catch some highly active yeast for future batches. I have never used top cropped yeast before.
