You just have to wait until the pressure builds after the needle valve. But opening the needle valve speeds up that process.

I have taken it out - checked and there was no water in the tube. I opened the needle value all the way for a a few seconds and still no change. I give up.

Maybe you have a leak or a check valve installed bacwards remove the diffuser and see if co2 is coming out of the hose. Then the check valve to isolate the problem.

Use soapy water to check for leaks at all connections.

Yup - one step ahead - I tried both of those. Took the check value off and there did not seem to be anything coming out of the hose at all.

I just shut everything down. I will have to wait for Green Leaf to call me back.

Is the bubble counter installed upside down the nipple inside the bubble counter should be pointing toward the diffuser not the co2 tank.

Everything was put together by Green Leaf - it shouldn't be upside down.

Take the hose off of the bubble counter and if you get no flow then it is either clogged or installed backwards and just building pressure if it is bubbling that is the only thing it can be.

If you get no bubbles at all then it is the needle valve or regulator. Unscrew the bubble counter cap where you fill it with water and see if you can blow through it if not something is clogging it the check valve is in the bottom of the bubble counter where it screws on the needle valve not the top so you should be able to blow through it if not it is clogged.

I took the top off the bubble counter and it is all clear. Not sure how to check the check value at the bottom of it. The reason I decided to spend $375 on this regulator is because I didn't want the challenge of having to buy everything separately and put it together myself. Not thinking I got my money's worth now. LOL.

Is the bubble counter bubbling when you turn the co2 on? If it is then connect just the hose and put the hose end in the water if you get bubbles out of hose then all is well. Then connect the diffuser to it and wait 30-60 minutes for it to start working if still nothing you got a bad diffuser or it needs extremely high working pressure which is sketchy past 50psi. That is all it can be you have isolated everything else.

Also if you have an inline check valve after the bubble counter try it without that installed that could be faulty.

1. Just bubble counter connected you get bubbles-The bubble counter is good.

2. Connect hose put open end in water if you get bubbles-hose is good and not clogged.

3. Connect check valve on just one end put other end in the water if you get bubbles- check valve is good.

4. Connect diffuser put in the water if no bubbles after an hour then the diffuser is bad or needs too much psi to operate.

5. This is the process of elimination.

Ok - there were bubbles coming out of the end of the tube. I replaced the brass check value with a cheap plastic one I had - we'll see if this works. By the way - I cannot blow through that check value - I should be able to right? Perhaps it is a bad valve?
