What's the problem with brass? I have a brass or bronze headed center inlet 815 pump from march. Give it the vinegar peroxide soak and I think it'll be fine. If there is any lead exposure at all it would be minimal. Imagine how much could possibly get into your beer and then think about how...

Liquid will not backflow up the line as the keg equalizes. The keg will only reach the same pressure as the regulator, never more than that. For the beer to backflow the pressure in the keg will have to be greater than the pressure from the regulator. To reiterate, liquid will not flow unless...

I would take the ball lock kegs. Are they actually ball lock or converted pinlock? 2 pin lock kegs will not fit in my kegerator, too wide... Any idea on shipping costs to 33569?

I vote jb weld. You can attach anything to anything using jb weld.

No, he is advocating for the use of straight nitrogen in place of beer gas. Then top up occasionally with co2.

No, the serving pressure isn't making it foamy. The line could be longer allowing for a more gentle pour. But at 8 psi I don't think that is the issue. The beer is very likely over carbed. Purge the keg and let it sit over night before putting it back under pressure and see if the situation...

If it is over carbed then purge/vent the keg a couple times until problem subsides. The most consistent way to carb is to let it sit at serving pressure for 1-2 weeks. It would probably be drinkable about 7-10 days in. That said, wheats are usually well carbonated, are you sure you have...

+1 Check your volumes of co2 using a carb chart. How many volumes at your pressure and temperature?

If you must force carb then set regulator at serving pressure and shake. Then let settle overnight. The elevated pressure method is a gamble as you have discovered.

Haven't used it on a batch yet but I went with a march 815 (the high flow) center inlet with a bronze head. It was about $175 shipped from tesco pumps. It's rated to flow 8 gallons per minute which I think will be adequate for 10 gal batches if it is plumbed properly. I am building my new rig...

I'm following this with great interest for sediment free transfers from my sanke fermenter. Why do think you need a screen? Just stop the transfer when the beer gets cloudy. The grainger float is neat, but I think you need something non round. The tube needs to be secured to the bottom so the...

You know, that's a cheap and simple solution. 25/75 mix would imply 1 of every 4 pints should be served using CO2 at the same pressure as the nitrogen. Just add a second regulator so you have your low pressure CO2 for the regular beer tap and a high pressure CO2 for the nitro stout. I bet you...

Well then, sorry that wasn't more help :o

I have one that could be borrowed but not repurposed (still have the drill) that is 18.2v 210mA. I also have a lawnmower battery charger that is 13.2v and 140mA. I probably have some other things around too if I look a bit harder. Maybe a couple cellphone chargers too. What sort of mA do I...

That's a thoughtful response. To clarify, my point isn't that carbonation doesn't matter or is imperceptible. It is. My point is that this is less so with beers served through a stout faucet. The restrictor plate effectively degasses most of the co2 out of solution anyway. I've experimented...

With the air gun how tight is the seal between the nozzle of the air gun and the copper tube? It should be tight to prevent the air from backing out of the tube. You want positive pressure. If you are pressurizing that tube, even a few psi, I bet that clog will move. Edit: you could try...

How many psi are you putting into it? Have you tried it again after running water through it? I would consider lye but I wouldn't use my pump to move it.

Obviously I'm not one of the physics experts in this thread but, as a practical matter, I've noticed that CO2 levels are not super critical. If the beer is about 1-2 volumes of CO2 the pour will be good. It's about experimenting with the serving pressure and this too will be affected by the...

A protein rest during the mash if you're using wheat malt ;) Whirlfloc Secondary Serve it a bit warmer That's probably not the answer you're looking for, I know. I've been following this thread and contemplating filtering but my beer turns out pretty darn clear using the above steps. If it...

So you need a power source, case fan, and stir bar in addition to the controller right? What are you using for the dc power source? I have an old charger for a cordless drill, would that work? How do you wire it all up?
