Put the CO2 tank higher than the water level? or just run the CO2 pipe higher than you tank water level. May not help if you used external reactor though. Never try, just a though
Hi bros,
Just noticed that my CO2 Canister is 1/2 filled with water from backflow!!! I think this happen when my supply of CO2 ran out. I have a check valve/bubble counter but this still happen. Read through the other threads but there doesnt seem to have a reasonable solution...
Now I have to pay the LFS to drain the canister again before it can be filled. SIGH.
Any good solution to this problem?

Heh thought of that before, but then my water level is like 1.5m. I think it will look funny if i put it that high.
Alternatively, maybe i should just refill my tank every few months...
how about just route the air pipe/hose higher than water level, the CO2 still can be below the tank.
a preventive measure is to use double check valve, which is two check valves in series.Originally Posted by Franz

Are you using 2 check valves? One before the bubble counter and the other after the bubble counter?
BTW i'm not sure whether it's still safe to use the cylinder even after the water has been drained out since the inside will still be a bit wet.
yes. i have 1 before and 1 after the bubble counter.. just for double protection.. because i've seen backflow with a single check valve. i guess that check valve is not 100% effecient.

in this case, check ur check valve, it might be faulty.. try changing to a new check valve see whether it helps.
get good quality check valves.
have extra co2 tube length between regulator/solenoid and bubble counter.
and does your regulator still work? almost everyone mentions that water will damage co2 regulators.

Hmm, I think the regulator should still be ok. I've drain and top up the tank. Gonna get another check valve when I collect the tank
My check valve comes with the bubblecounter wor. If I gonna add another check valve, should I put it before or after the bubble/check valve?
Resistance is futile, you will be administrated!
Normally, the first check valve is for the bubble counter, the second is for the regulator.
If CO2 remaining in the pipes backflow into the typical bubble counter (i.e the type with one short tube and one long tube inside) the CO2 will force the water in the bubble counter up the long tube and towards the regulator. In extreme cases, the counter will be emptied of water and cease to function (although CO2 may still flow through).
The second valve is to prevent the water from the bubble counter from getting into the regulator.
I suggest you pay a little more, get 2 GOOD bubble counters and install one just before the bubble counter and one just before the regulator.
Is your bubble counter that is labelled as the 'new' type in the photo in this thread? If it is, you can't install a check valve after it. I will also suspect that the check valve on your bubble counter is not functioning properly.

La La La, hahaha, first off, you are right. I'm using that kinda check valve.
Secondly, it's kinda stupid, I used it without any liquid in it in the first place :P Had been wondering why isit call a bubble counter when there is no liquid, so how to count the bubbles...

Considering that you never put liquid in your bubble counter and water still gets into the cylinder, then there is something seriously wrong with the check valve.
Chuck it and get a new 'conventional' bubble counter and two checkvalves. I particularly like the ones sold by System and Control Engineering (aka Bioplast). I think they only have one type of each, but if they have more types, the ones I'm talking about are made of black and transparent parts.

yes use 2 check valve with bubble counter. i also experienced backflow with single check valve.
