check valve on regulator, do i need them on the rest?

Rivenin · 02-07-2012, 08:21 PM

On my kegging setup, i have a check valve on my regulator output.
in that case, shouldn't i be able to make a cheap manifold without check valves? just run a splitter with valves to the rest of the kegs?
makes sense in my head, just wondering if it'll work/be safe

like this...

except with some basic valves that i could turn the gas on and off with

Yes- the reason to have check valves is to prevent back flow to your regulator. It won't hurt to have them on each shut off, but you don't need them to protect the regulator.

thanks yoop!

One potential downside to this is if you vent one keg enough to cause it to foam you can get foam transferring to the other keg through the gas line.

Just a heads up.

Why would you vent with gas connected?

You should not do that but it can be done.

I've been known to do things I should not and felt the info could be helpful.

I have pin locks with no vent on the lid, so I'm safe on that end. Thanks for the heads up though! I'm sure one time or another I would have done that though... lol.

Also if you vent at the regulator (say to purge / remove the reg) and you had a keg still under pressure that:

♠ Was full w/liquid above the gas post
♣ Had an installed dip tube w/air stone
♦ Accidentally connected (forced?) the gas disconnect to the out post
♥ Etc.

You would then have liquid run into the gas line and into the other keg (assuming the other keg had a slight decrement in pressure… say by a pour). The liquid would only stop at the check valve, assuming the check valve worked; otherwise liquid would end up in your regulator. Things happen, especially when changing kegs after a few.
