Review: Everything you need for a cost effective retrofit to large, refillable tanks. - I have to admit I was pretty skeptical. I have one of the first and simplest Sodastream makers (canister holders) and figured there might be some serious issues retrofitting an old but full CO2 canister a friend cast off from a defunct keg fridge. Didn't I need a regulator? Was this going to blow the seals? was that hose going to be strong enough? After using this for several months I can say that this is everything you need. No regulator needed - the gauge shows a constant near 1000 psi. I cut a notch in the bottom of my Sodastream to accommodate the hose through the base and it works great. In the first month I had a couple issues with some kind of back-pressure, but there is a bleeder valve near the pressure gauge, so it's easy enough to cure. Really no issues since then. Maybe eventually this setup will kill the seals, but so far, in savings it's paid for itself, and a replacement Sodastream base if it comes to that. Update: was having an issue again with not getting CO2 through the nozzle, so I went through the process of tearing everything down to see if there were issues with the seals. After looking at how the entire system is designed, I wound up resolving the issue by running a small needle through the end of the nozzle that injects into the water bottle to dislodge some piece of debris that found its way into the system. This is something that could happen even with the regular bottle exchange - and is perhaps even more likely with more frequent changes. After examining the connections and essentially very simple design of the system, I can say with a fair amount of confidence that you would be extremely unlikely to have "seals" fail (and that cleaning a blocked nozzle is something that can be done without tearing down the entire system). If the bottle is over-full, you can get some leakage through the pressure seal especially on the first injection, but after air drying between uses, it's an occasional minor annoyance that is easily prevented by either not exceeding the fill line or using a more gentle press on the first injection.

## Questions & Answers

**Q: Cn this be used for a sodastrem 60l co2 cartdri?ge**
A: To refill the bottles, you will have to also get this item.  
https://www.amazon.com/gp/product/B08B4RGT2W/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
I bought the other item first to refill my bottles and this bought this item to run my Soda stream directly off of a bigger bottle. That did not work as the pressure was too high. The ends of both kist are Quick Detach so I just swapped them. The biggest thing you need to know is the Soda Stream bottles have a safety valve inside them that shuts off if you fill the bottles too fast. Filling it slowly is the key. I use a food scale to see that the bottle is getting heavier and also gauge how much CO2 I am putting in the bottle as it only holds 14.5 ounces of gas. Don't overfill it or the relief valve will pop rendering the bottle useless.

**Q: Do you have to turn the gas off at the tank between uses or can you leave it on all the time?**
A: I've had an instance when the tank leaked to empty. So I close the valve when I'm done using it.

**Q: My Co2 tank has a siphon tube. Will this still work?**
A: I use this with a siphon for a while. However I think it caused the gas to freeze and clog and break the infuser. I was going to kill my 10lb Tank and switch to a non- siphon tube one but guess I’ll have to do that sooner then I thought.

**Q: I'm looking for a longer hose than the 5ft one which came with this kit. Any tips where to find a 10 ft hose?**
A: This vendor offers longer hoses, check in with them.

### ⭐ WASTE OF MONEY
*by K***9 on 5 June 2026*

WONT WORK IN AUSTRALIA. THEY SHOULD HAVE THAT ON THE PRODUCT AND THEY DONT!!! Absolutely useless. Just try to connect it up for the first time and it won’t even connect. What a waste of money. DONT BUY! It won’t even screw on to the co2 bottle I bought from keg land. Just buy one from them.
