I noticed in another thread that Bobby M and others were having issues with air getting into his system, and he was suspecting his MC QDs... I have been eyeing the cam locks from bargain fittings, because when hot liquid has just flowed through a hose fitting, it's not fun grabbing those things and trying to loosen them...

Is anyone else having issues with QDs leaking air into the system under vacuum?

Also, how much do you trust the cam locks?

I want to tee off of the drain output from my keggle and the resulting plumbing is going to make the keggle cumbersome to move around with it still connected... So the obvious answer is a QD of some kind..

Trouble is, with a ball valve in each leg of the tee, I'm wondering if it's necessary to put an additional one at the output of the keggle before the disconnect...

Seems like extra cost for a redundant valve, but I'd sure hate for a QD to come loose unexpectedly spilling hot water or worse yet, boiling wort all over the place...

Do you guys trust these cam locks enough that you don't put any sort of shut off valve between them and the pickup tube?

I'd need them in 4 or more places, and the price starts adding up, so I want to get feedback from those that have been using them for a bit..

Thanks

Do you guys have a valve before the first disconnnect, or do you just have the disconnect immediately outside of the kettle?

I can't speak for the QD's but I try to valve everything that I think is important in my system. Valves are relatively cheap ($10 to $20) and sometimes they can save the day.

That's kinda what I'm thinking and why I asked the question..

I see all these pictures of peoples high dollar brew rigs and there's nothing but 'QD' attached to the keggle or kettle.. and it makes me nervous..

So I'm wondering what the general consensus is on trusting these things to keep 10+ gallons of boiling wort from inadvertently spewing all over the place... If one accidentally gets bumped and somehow comes loose, I see no way to stop it until it completely empties the vessel...

Turning off the ball valve stops the flow!

I have a ball valve that the male QD screws in to on my kegs, pumps and rims. Hoses are female QD on both sides with barbs to the silicone. All MC.

Some QD's actually have a valve built into them. They are called "Dry Disconnect Couplings".
