Right, if the terminal output of your pump is also under water when you open all the valves the air trapped in the lines does not readily escape (i.e. whirlpooling JZ style) I open my quick disconnects to allow the beer to flow until I see all the lines cleared of air at the impeller end. This has worked well, even though recirc during a boil sends plenty of air bubbles in your pump head anyway. Cavitation is a bitch!

I have added a 3 way valve on the outlet side of my pump. It allows me 'burp' the pump if I happen to get an air bubble in the chamber. It is a whole lot easier than moving hoses full of boiling wort.

I have the pump inlet on the bottom and a cross on the outlet. On the outlet going to the right, is a valve I can open when I'm priming the pump so remove any air inside of the pump head. Once that's done, I close the vent valve, turn the pump on, and open the outlet valve to begin pumping.

You guys are great. This is what I love about HBT, ask a question and folks line up to help. Awesome! As I read more from the replies, I just realized that after I change the out flow to the top of the pump, I will be able to use the ball valve I normally use throttle the flow from the pump to control the bleed out of any air. Once that's done I just slap on the return line and start pumping. So I already got purge mechanism, just didn't know it! Keeps getting better.

How do I prime my pump? I whisper into my wife's ear and she takes over from there.

Sorry, I couldn't resist.

I'm glad there were so many helpful folks on here to actually help you.


My wife is like a well crafted beer...bitter, yet sweet enough to balance perfectly!
