Are you referring to the valve of regulator?
If so, it will be before the bubble counter, as the bubble counter is used to see how much CO2 is being injected!
Right after regulator
After bubble counter
Before Diffusor
Not sure
No more saltwater tank for me!
where to place control valve?
do we place it at the mouth of the canister before bubble counteR? or after bubble counter ? or right outside the tank before diffusor? im confused...

im talking about those cheap control valve to prevent backflow of water into co2 canisterOriginally Posted by evolim83
Logically, it would be before your regulator and after your bubble counter...
The check-valve, as it is called, is meanted to prevent backflow... So the on between the regulator and bubble counter is to prevent backflow from the counter, while the one between your counter and the output to diffusor/reactor is to prevent backflow from the tank...

oh so i should get 2 check valves?
Yupz... They are cheap anyway... Better to be kiasu than to have water flowing into your solenoid or regulator and spoiling it...
My "cheapo ones" tend to kinda stop working after a few months. Was horrified to see water going back the tube one evening. Luckily I put 2 and it prevented any harm.
Nowadays i put new ones after a few months

huh? how come can spoil ?? isnt it some plastic thingy?
The check-valve is not 100% effective!
Sometime, back flow still occurs!
I have 2 check valves too, one is the one built-in one that comes with the JBJ bubble counters, the other is the cheap plastic one!
I would suggest you position your check valve as near to the diffusor as possible to reduce the amount of back-flow!
The plastic ones sold by LFSes are not effective check valves as I was told.

so what type of check valves are the best?
