So I have the ista co2 dual reg and I believe the bubble counter is supposed to have an in built check valve.
My co2 comes on at the desired time with solenoid but sometimes bubbles won't appear out of diffuser on time. Would sometimes be delayed.

I'm assuming it's the co2 pushing water also therefore slowing it down. And i have had to empty water out of co2 tubing before.

Is it worth adding another check valve in tubing ?
 
Hi Shane
Yes, add another check valve just before the bubble counter, that stops water from the bubble counter moving back up the Co2 tubing!
