Does DIY CO2 Need Check Valve

Does a DIY CO2 setup require a check valve. I installed one and I don't know if required or if it will work. Dont want my 2liter bottle to blow up cause the check valve isn't letting gas through.

If in doubt, add more plants!

Check valves are a safety measure to keep the DIY bottle from siphoning water out of the tank. Not required, but a good idea. Don't want to use one? Place the water line of the bottle above the water line of the tank.

Ok. Thanks. Was just wanting to make sure.

Check valves are also handy for keeping the lines pressurized when you have to take part of them off-line. This is especially true when using multiple bottles in your system. I ran 3 all together staggering a change-out once a week. Using check valves I could keep the system pressurized when I took the oldest one off the system to renew it. The other two bottles remained pressurized and continued to deliver the co2 despite the fact that there was one missing.

Yup. I have seen a couple of pictures on the board over the years of people having their yest mixture ending up in the tank after water siphoned down from the tank and mixed. Didn't look like a fun cleanup.

Let's just say that trying to get four liters worth of yeasty, smelly crud out of carpet along with a very good portion of water from a 30 gallon tank is NOT fun.

This guy wishes he had used a check valve...big time.
