# 2411 - CO2 Gas System [[Home Brewing#Projects|Projects]] I'd been toying with idea of installing a proper gas system and get away from the plastic kegs with CO2 bulbs. I'd used the mini party style kegs for a while, but they'd started to develop leaks and weren't as reusable as I'd hoped. Towards the end of 2019 I was getting serious about it, thinking that I'd give it until after Christmas (avoiding the holiday purchases). Along came Covid and CO2 was nigh on impossible to obtain locally; my home brewing days were nearly over along with any ideas of introducing a CO2 system. The hiatus in brewing had done me a favour, when I rekindled my interest SodaStream cylinders were a popular choice; having done the math(s) they appeared to be a convenient and cost effective option. Fortunately there's a Argos within 10 miles with a cylinder gas exchange facility. Gas system installed beginning of November 2024, with the later addition of the [[2025 - Keezer 1.0]] [Argos](http://www.argos.co.uk) for the SodaStream cylinder, [The Malt Miller](https://www.themaltmiller.co.uk) for the regulator and tubing. ![regulator](SodaStream%20-8.jpg) ![sodastream](SodaStream%20-7.jpg) ![regulator](SodaStream%20-5.jpg) ## Refill January 2025 Cylinder empty and needing an exchange. ![regulator](SodaStream%20-4.jpg) Exchanged and a spare purchased. ![regulator](SodaStream%20-3.jpg) ![spare cylinders](SodaStream%20-1.jpg) ![regulator](SodaStream%20-2.jpg) ## Gas Leak Losing some pressure in the line between the manifold and the keg. Isolating the keg showed that it was OK. I suspected that the problem lay with the angle of the lines coming out of the manifold, designed to be used at 45°, where my system required the lines to run parallel to the wall. **Solution** - make an angle bracket. ![The Gas Board](IMG_0712%20Medium.jpeg) Bracket fitted, angle of the lines reduced and no obvious leaks. Line pressure had dropped overnight, but this may be due to the drop in keezer temperature. ![Bracket fitted](IMG_0714%20Medium.jpeg) ## The Leak Continues The bracket hadn't fixed the problem so I then suspected the pressure gauge. Hadn't taken into account the permeability of the line itself, my rough calculations of [line loss](https://www.themaltmiller.co.uk/wp-content/uploads/2019/01/BAM265375.pdf) fits with what's been leaking. I will be swapping all the gas lines for Valpar Gen-X lines, and reducing the number of joints. ### Update Swapping the lines appears to have done the trick - pressure holding. 👍
