Do cheap gang valves work with DIY co2?

I just installed my first DIY co2 about 6 hours ago and I hooked the tubing to this gang valve so I could shut it off at night. I see bubbles coming from my bubble counter but no bubbles out the end of the tube thats in the tank. I've made sure to seal every single bottle I have. This makes me wonder if the gang valve is leaking co2...unless its supposed to take longer for bubbles to reach the tank?

Most DIY CO2 is not cut off at night.
I let it roll 24/7 since it is low PSI.
I avoid pH swings this way.

After some fiddling, I managed to get a constant 3 bps. I have a 25 gal. I read somewhere that if you have a 2L reactor per 10 gal you can keep it on at night. I have 2L reactor per 12.5 gal. I guess that's good for all nighters? I just want have some peace of mind knowing I won't gas my fish.

I don't have/use DIY co2, but for any of it to work the best it should be turned on an hr before the lights go on according to those threads which I've read. Assuming it's off at night that is. I have no exp/w that so my thinking that it still should be off at night
may be my over thinking it. I just recognize that there is a difference between could
and should. I would divert the flow rather than turn it off.
But I have found that those new gang valves on the market to day are a very sad
replacement for the old chrome planted brass one. Not in the lest accurate especially
pertaining to consistent flow. I recently bought one of these to see if it's any better
than the plastic ones, but have yet to try it out.

The shortest distance between any two points is a straight line...in the opposite direction...
