Hey gang,
So I've been using my spare keg to make seltzer since my wife loves flavored seltzer and I thought it was silly to buy bottles of seltzer when I have a perfectly good carbonation system sitting at home. It's also really nice during the summer and we go through 5 gallons pretty quickly. I'm getting tired of having to refill the keg every 2-3 weeks and shake it to carb it up faster, so I came up with a cunning plan that I wanted to run past the forum.
I've designed but not tested a constant filling system for my seltzer keg. Currently I have a carbon filter that I hookup to my faucet and run the output hose into the keg when it needs to be refilled. Well I wondered if I could just run the hose straight into the keg and it would refill the keg as the water level dropped. So I've come up with the following solution:
The above schematic demonstrates my idea. I'm filling up the keg through the gas in port instead of the liquid out so uncarbonated water cant go directly to the tap. So the cold water supply from the nearby sink goes into a Tee to split it into keg supply and faucet supply. That then goes into the filter which is not shown, but is located between the 2 compression fittings before the QD (which is a free dripless QD that I scored as a sample). the QD then goes into a check valve (to prevent gas from entering the water supply) and into a flare Tee that connects to the Gas QD. The gas in line connects to this Tee with another check valve to prevent any water going up the gas line, even though there is one at the manifold, I'm just being extra cautious.
I figure this will work because the water pressure is probably higher than the 30 psi that the keg is at so water will still flow into the keg. I haven't measured but I probably should measure the pressure after the filter before making all the effort to construct this system to find out it doesn't work.
What do you guys think? Am I crazy or a genius or a little of both? If I do get this working I'll be sure to post a build thread with pictures and results. I'm crossing my fingers for success! Now that I think about it, I might also ask some of the plumbing engineers that I work with and get their professional opinion on it.
