## Questions & Answers

**Q: How does one engage the pin valve on the Sodastream cartridge while using this adapter?**
A: The pin does not get depressed during filling except by pressure.  This valve has a second valve stage, if a pin lying behind pushes back too much pressure through the valve, it closes from the inside. A manual operation of the valve pin during the filling process does not bypass this function. This cylinder valve is possible only with slowly increasing pressure.)   I had similar issues with the 3rd gen soda stream bottles… try this…
 Ensure the bottle is completely empty. Chill the bottle in a freezer or deep freezer (I did mine overnight).. Screw the bottle on the side.  Open the thumbscrew on the adapter... slightly use a glove to avoid issues with high pressure CO2.  Open the CO2 tank.. Slowly close the Thumbscrew.. you will hear the tank start to fill.   Slowly open the main CO2 valve.

**Q: Is this made of solid brass?**
A: Yes

**Q: I've lost the extra gaskets that came with the product. What are the specifications for them, so I can purchase replacements?**
A: The smallest is a #60 o-ring, 1/4”OD x 1/8” ID x 1/16”.

**Q: Hello, how do I make sure to not overfill my Sodastream bottle with your adaptor?**
A: I've never gotten past about half full. Would love to go fuller to have more time between reloads. I weigh before and after, and I can add 200-330g.

## Customer Reviews

### ⭐⭐⭐⭐⭐ It Works, and it will save you some serious money in the long run.
*by M***Y on November 10, 2020*

Product arrived on time with no damage (plus for the seller). The item is just as advertised, and if you follow the directions in the video on how to fill a little tank from your 5-10-20 pound bottle (yes, upside-down) it works perfectly.A couple of items worth mentioning and some cautionary notes:1) The bottle you are filling needs to be certified, so check the last time the bottle was static tested. Don't fill a bottle if the certification had expired.2) There are no directions, so make sure you put in the O-Rings that come with the adapter. The black rubber one on the pony bottle side, and the white nylon one on the supply bottle side.3) MAKE SURE you put your little pony bottle in the freezer for the night before filling it. This is critical to get liquid in your pony bottle, not just gas.4) After filling my first two bottles, I noted that my full bottle was a deal higher than the standard fill I got with exchanging bottles..5) Lastly, this is highly pressurized gas, treat it as such. Wear PPE, and don't play around or allow the bottles to tip over or to fall off the bench, you might really regret it .

### ⭐⭐⭐⭐⭐ Super easy to refill Sodastream bottles with this, finally.
*by M***S on October 28, 2020*

Finally an easy way to refill them. I tried the hose adapter to go from my homebrew CO2 tank straight to the Sodastream, but it ended up tasting like factory. Rather than making one myself which is clean, I first tried this adapter for a refill option. Welp it is easy enough that I'm done - this is my pandemic sodastream solution. The bottles end up with WAY MORE gas this way than when you buy the refills at the store, they last way longer.And it goes a little something like this:1 - Empty bottle to be refilled goes in the freezer overnight. I tried with one in the freezer for just a few minutes and it worked fine, just held less gas. I keep an empty in the freezer all the time now. General gas equation PV=nRT means colder bottle holds more gas.2 - Install the o-rings right (white washer on tank side, black o-ring on sodastream bottle side, and the little o-ring for the vent valve). I applied a thin film of keg lube on the washers and rings because why not.3 - Crank the adapter onto your source CO2 tank, with valves shut on the tank and the vent valve on the adapter. Use a wrench on the tank connection. You can leave it on the source CO2 tank until you want to use the tank for something else.4 - Crank the frozen empty bottle onto the open end of the adapter, hand tight like in the sodastream machine.5 - If you have a regular homebrew CO2 tank like me, you have to hold it upside down so the liquid CO2 wants to fall into the frozen bottle. Then you open the tank valve VERY SLOWLY until you hear the CO2 flowing. You can open it wider slowly once you hear flow, but if you open too much too fast it will trigger an interlock in the bottle pin and shut off the flow completely. Just fill it slowly, takes about two minutes but you're saving mad cash.6 - Once you think you've filled it, shut off your tank valve. Then open the vent valve on the adapter to release the compressed gas inside the adapter and allow the bottle pin to shut (pressure holds it open for this refill process, nothing touches that center pin). Then take off your newly-refilled bottle and wonder at its weight. In fact, I always use a food scale to measure the bottle empty and full, to reassure myself.The sodastream bottles last us at least two or three times as long as a refill as compared to when they're new refills from the store. Mmmhmmm.... Go. Figure.

### ⭐ It does not work with the new Sodastream bottles.
*by D***D on October 29, 2021*

So, I took this to my local paintball shop and we spent an evening trying to fill it up. We did everything as instructed in the reviews. We turned over the tank, we used the o-rings, the bottles were real cold. It did not work. Not even opening the big tank slowly. The pressure inside the adaptor is not enough to refill the bottle. Total fail.Would not recommend. just caved in and got a 20oz paintball tank and used that instead.
