Default $10 Three way MFL manifold

So I needed a manifold for my trashcan kegerator. I didn't want to take out the one in my "Carberator" since it's attached to a dual guage secondary regulator. But I did want to be able to use 3 of the gas disconnects which attach to the manifold and regulator with MFL fittings. I wanted to be able to take them off use them for the day in the trash can then put them back on fridge duty.

So I went to the local place that carries every nut/bolt/washer/fitting known to man.

For $10 and some teflon tape I assembled my manifold. Last picture shows a MFL connected to it.

Nice...

One minor upgrade might be to use check valves on the outputs. Example:

At some point I would like to put a check valve on the line to the regulator but no one sells them around here for under $30 (some sort of welding thing) so sometime when I do an internet order I will grab one.

If it were me, I'd put one on each output... otherwise when you pull liquid from one keg, gas will equalize from your tank AND the other kegs.

$2.49 1/4" MFL to 1/4" NPT with check valve FTW

Put some duct tape over the gauge - Or better yet - Replace the high pressure gauge with a plug - High pressure gauges are useless!

I'm confused I thought the check valve was to keep beer from flowing back up the line and into your regulator in the pressures in your kegs got higher than in your CO2 tank????

... otherwise when you pull liquid from one keg, gas will equalize from your tank AND the other kegs. Why would this be an issue?

It can be.

I've had liquid pull into a gas line when I had a keg really full. It can happen.

When you pull from a keg, the pressure will drop. Without check valves, it'll equalize from the other kegs and the CO2 tank.
Not that that's a huge issue, but it's there.

I think $10 worth of check valves are a small price to pay to protect a $100 regulator.

It does. It also, can prevent gas, or beer (if you jostle a keg and end up with beer in the gas line) from moving from keg to keg.

Not a huge worry (I said a "minor upgrade"), but I like the idea of isolating the kegs from each other. For $2.50 each, the check valves are a pretty small investment.

These kegs aren't too full and I will be using a brand new, newly filled 5lb co2 tank. Will I be ok to distribute beer out of my trash can kegerator for like 8 hours with no worries.

I will get the check valves when I can in the future.
