    Spunding valve between the two kegs or at the end of the chain?

    That's right. I was just reading @doug293cz 's post on purging with fermentation gas. He puts a jumping line between the kegs, not a spunding valveven keeping the fermenting . Having said that, even with the tank under pressure, the exit pipe is still hammering away for three to four days...

    Spunding valve between the two kegs or at the end of the chain?

    Oh, the kegs in the photo are different sizes. But normally all the kegs are the same size. So go on that assumption.

    Spunding valve between the two kegs or at the end of the chain?

    Like many of us I use the fermentation co2 from the fermenting keg to purge the serving keg. But where to place the spunding valve? Photo below shows how I currently do it. The spunding valve is in the middle, after the fermentation keg and before the serving keg. So the fermenting keg...

    Stuck pump

    Hmm. The pump is getting power as it hums when I power on. The power in the windings is just not doing that thing of circling the magnet. Might just be a pump that failed. And has nothing to do with being clogged at all

    Stuck pump

    Yes. I have turned it on with the cover and impeller off, looking just at the center magnet. No movement. If I spin the center magnet with my finger, it spins great. I have written to customer support at Kegland, and have also posted to the Kegland user forum. I guess I'll dig out my...

    Stuck pump

    Well, no luck. tried it with water, to see if the problem was a lack of self priming. not that. I think the pump is just not getting power. when I turn on the pump, I hear a click in the power box beside it. But the pump does not spin. the impeller can be in the tightly bolted down as...

    Stuck pump

    Yeah, first time I took apart a magnetic coupler pump. Now I know why that is different than a mechanical pump. Super cool that there is no mechanical contact and it's just magnetic fields. Now i know why I can throttle it back on the recirculation pump without harming the drive. after...

    Stuck pump

    Yes, I can turn the motor/magnetic coupler by hand. There is no resistance. I have taken it out and put it back several times. It will turn freely. I can only assume that those damnable seeds have blocked the spin so much that there is some electrical damage

    Stuck pump

    Oh, wait, it's not a self priming pump. tomorrow morning I'll install, it flip it over and add water. We'll see.

    Stuck pump

    When I turn on the power I hear a click in the pump, so power is getting to it. But there is no motion. I opened the back and saw the wiring and all is good. Nothing is burned out.

    Stuck pump

    This is a newish Brewzilla gen 4, 35 liter. This was my first stuck pump. I think the culprit was crushed grains of paradise. The black seeds are in the photos below. Doesn't matter. The pump took out most of the wort, enough so my fermantation keg is filled and going fine. But then...

    Purging Oxygen from a Keg by Pressure Only - the calculations to determine time

    That is very helpful From that, it seems that a fermenting keg can fully purge a connected serving keg, I had thought that pushing through a keg full of sanitizer was required. But maybe not. I’m sure there will be controversy on this.

    How much oxygen gets introduced to the wort when you add the grains?

    Also, I am curious about what BrewTan actually does. I see comments that it helps with the effects of copper chillers, and that SS chillers do not need this help. Does BrewTan, which I think is just tannic acid, interfere with the reaction between copper and oils? I know that in cooking...

    How much oxygen gets introduced to the wort when you add the grains?

    I have sms and have ordered Brewtan. At what stages would they be added? I have a copper chiller that I will use to chill the boiling strike water and then again to chill the boiled wort

    How much oxygen gets introduced to the wort when you add the grains?

    I’m not aware of the trifecta. What is it, please

    Poor man's hop bong

    Yes, it’s starting to look like the bong is the preferred route. Plus the pet bottle for liquids. One member did mention a hopper. I can see how that would be better than just the tc opening. A large funnel holding a large volume of gas which is overflowing. Slowly submerge the hops...

    Very nice. I am going to build one of those

    Poor man's hop bong

    I put that bong unit on my wish list. But in the meantime, my question is this: Some folk are just using positive pressure when adding items on the cold side. Wouldn't that be enough? While a bong looks cool and fun, positive pressure is effectively used in labs to keep outside things from...

    Very interesting, thanks

    Poor man's hop bong

    While I"m not full on lodo yet, I do like the idea of keeping the atmosphere out of my beer. Hop bongs are pricey. And they don't help you introduce liquids, just hops. I ordered a keg lid with a 1.5 inch tri clover top. The idea is that I use this lid on my fermenting keg. When it...
