SodaStream CO2 and Malt Miller ODL regulator

Jonny Ford · Jan 13, 2019

I have the premium CO2 regulator from Malt Miller (https://www.themaltmiller.co.uk/product/premium-co2-regulator/), as well as the Sodastream adapter and bottle.

I’m struggling a bit with working out how to connect it all up.

Everything is physically connected correctly. Bottle onto regulator. John Guest to 3/8th to a gas disconnect.

Where I’m confused is when I connect the CO2 to the regulator I can hear and feel the gas coming out very quickly.

How do the sodastream bottles work?
Do they need something pressing down for gas to be allowed out or are they like the small chargers and need to be pierced?

My guess is that I just need to tighten up the bottle onto the regulator further to actually create the seal needed for it to not just shoot gas everywhere.

Also, once all is fitted do I need to keep the disconnect connected to the keg with a sodastream bottle as there’s not a knob to turn on/off the gas.

I can't help much but the bit in the middle of the regulator should turn to change the pressure so if you turn it anticlockwise it will go down until it's off. The corny disconnect should hold pressure when not connected but will leak slightly if left off for long or at least mine does, it's fine just to change the keg though.

I think you just have to be quick with the soda stream bottles. Did you follow the instructions on the MM site?

https://www.themaltmiller.co.uk/product/sodastream-adapter-for-co2-regulator/

That wee pin on the adapter is what pushes into the sodastream cylinder allowing the gas to flow through. Gas will pass through the threads until the adapter is screwed tight and allows the dowty seal to prevent leakage (black washer in below photo). Once hand tight, you shouldn't hear anything. Then once nipped up, it will be grand.

The gas disconnect shouldn't pass CO2 when uncoupled from the keg. I leave mine uncoupled and under pressure quite often.

As Simon says (unintentional clapa

), anticlockwise is closed and clockwise is open on the regulator.

I tightened up the "Connector" to the "Regulator" ...

... made sure that the "Regulator" was in the OFF position (anti-clockwise) before fitting it to the Sodastream bottle ...

... then I fitted the "Connector" to the Sodastream bottle quickly and only got a small "hiss" from the joint before it sealed properly.

Enjoy.

Sorry to dig up old thread but I have just managed to discharge an entire sodastream tank whilst trying to fit the f**king thing to my regulator.

I had two attempts.

First was screwing said adaptor into my existing (previously working and used for co2 pub gas tank) and I put a bit of PTFE tape as I wasn't totally convinced the thread would hold the pressure alone, should be no harm done right?

Anyway then screwed the sodastream into the adaptor and it hissed out quite drastically. So I unscrewed and thought again.

Second attempt I noticed an adjustable pin on the inside of the adaptor which I hadn't previously adjusted, so I did this time with it wound out (if that make sense) so the pin was not depressing the sodastream discharge quite as much as fully screwed in. Screwed into the regulator and then screwed in the sodastream... it hissed the remaining gas out.

So, wasted good money there straight up kick in the goolies as I have clearly done something stupid.

Any advice? Other details I've missed out in order to help.

I should mention the gas appeared (although I may be mistaken in the panic) to have come out from the adaptor and the sodastream

Can you confirm the Teflon seal is in place, it appears to be in your photo.
Back off the pin depressor anti clockwise.
Make sure the regulator control is turned fully anti clockwise.
Attach adapter to cylinder and tighten with suitable spanner.
Screw in the pin depressor.
If it still leaks I would say there may be a damaged thread on either the adaptor or the cylinder.

Aren't there 2 types of sodastream canister? i.e. old and new? I got given a canister for free and thought it would be handy as a back-up but the person that gave it to me said it didn't fit their sodastream device because it was the new type of canister.

uDicko · Feb 27, 2019

@phildo79 I bought a new one and used a newly purchased cheap adapter. I suspect it's me being a moron.

The silicone seal is in there @BarnBrian. I'll PTFE the sodastream as I suspect I should have done that when first trying, not the adaptor to the regulator.

I'll adjust the pin so it doesn't discharge everything so quickly when screwing it in!

Will report back when I've figured it out.

Thanks
