Review on 🍺 Ferroday Dual Gauge CO2 Draft Beer Regulator - Dual Stage Pressure Control for Kegerators & Homebrewing - CGA-320 CO2 Tank Compatibility - Dual Valve Precision - 0-3000PSI & 0-60 PSI Range by Monica Hall

I use this excellent Ferroday regulator for sparkling water. I also bought a carbonation cap (ASIN B01K4GGYT0) also made by Ferroday. This controller is very solidly built and only took a few minutes to install. Use one of the two included nylon washers to attach it to the tank. The high-pressure indicator shows how much CO2 is still in the tank. You can use the low-pressure regulator to adjust the outlet pressure. Adjust the outlet regulator to the desired outlet pressure between 0 and 60 psi. At first I had trouble setting the pressure above 30psi on the outlet regulator until I realized there is a locknut underneath that allows you to lock in the commonly used pressure. By loosening the lock nut I was able to set a higher output pressure. It was easy to set up and I now have unlimited sparkling water.
