Co2 Technical problem..AGAIN. This is torture...Need some help

First off, if the low pressure gauge is blown, replace it. It's not your problem here, but it's good to know what you are dealing with. Gauges are cheap. Go to a welding supply place and buy what they tell you to.

Secondly, I don't see an answer to this, so I'll ask. What happens when you completely close the first 3 needle vavles and turn up the pressure? It really sounds like some kind of blockage between valves 2 and 3. If nothing happens when you close valves 1,2, and 3 and turn up the pressure, I'd crack the manifold open between valves 2 and 3 and see whats happening inside.


And I understand what you are saying about Rex. As a hobbyist trying to help out other hobbyist, it's good to be patient with him, but as a businessman it's ok to hold him to a higher standard.

Right. So you want me to first...

Turn off all of the first three needle valves, and turn up the pressure, then you want me to unscrew the 2 last manifolds and try and blow some gas in the manifold?(compressed air can?) Do this with the solenoid on? Wouldn't there would be a major gas spray escape coming from out of the first two manifolds??
 
No, see below:


Start counting from the regulator, turn off the 1st, 2nd, and 3rd needle valves you come to. At this point, the farthest one from the regulator should be open. Turn up the pressure. What happens? Does gas bubble through or not? Without a working low pressure gauge, it's hard to tell just how high the pressure is, but, still, turn it up a decent amount, 20-30 psi. If nothing happens, then move on to the next step.

Next step, turn off the cylinder, purge out all the gas from the regulator. Now, disconnect the manifold where vavles 2 and 3 connect to each other. Inspect this connection. My guess is that there is something awry inside this connection.
 
Okay gotcha. I'll see what I can do. Thanks.

Before I try to resolve your issue, which 2 of the 4 are not working properly. Is it the two closest to the regulator or the two at the end?

I assumed he was talking about the "last" two downstream not working, but it clarification is definitely necessary.
 
The last two Nolapete.

jmhart, looks like the plan to turn off all three needle valves, turn up the pressure and turn on the last needle valve didn't work to create enough pressure to pull off. So I did the next step, I taken out the last two ports with the needle valves. I capped off the 2nd port's end though with a 1/8" cap to keep the co2 in. Now I'm left with two ports and the NV's attached. I don't about Nolapete's idea about exchanging NV's I don't want to risk busting something up...not like I don't like your dea or anything nolapete haha

Ok, my suggestion is this. Remove all the valves. Split the last two off of the four. Connect the last two to the manifold. Be sure to check for left over pipe dope or teflon tape blocking the pipe. Check the other two as well.

What I'm asking you to do will clearly demonstrate if the valves are blocked. Turning off the valves isn't going to check for blockages.

You might also want to try installing the working bubble counters on the non-working valves. This gives you a double check of the valves and the counters at the same time.

It seems like a hassle, but you have to determine where the malfunction is.

On a different note, why do you need 4 outlets if you only have 1 tank? Is the 60 the only tank you have or the only one you have listed?

Okay, I'll try that. I have one 60 gallon and three 10 gallons. So I have one for my 60 gallon, and one for my 10 gallon.

I suggest you look elsewhere.

If you're on medication then you need to up the dosage.
If you're not on medication then should need to be.
The payment email is for payment. Not for questions. But I know you sent an email to that address before you sent this one.
I will not at this time nor in the future do business with you.

Nolapete I told you he was arrogant =\ I guess I just had to send my email to his payment because I thought he spammed me on his advice account. Anyhow, I'm not on medication..!he wants me dead or something... >_> Oh, sheesh, all cause I wanted was his darn gauge. Looks like I have to go to a welding shop....sigh.

You forget that he reads this forum.

I'm going to say this one last time. You don't need a replacement gauge. Set the pressure at 11 psi and leave it alone. Increasing the psi isn't going to fix your problem. Whatever psi you set it at fills the entire manifold with that psi, so the two that are functioning and the two that aren't have the same pressure fed to them. Get it?

Your problem is NOT the gauge. Your problem is a blockage in the manifold after the first two that are working. It could be in the connecting segments of the manifold, the needle valves, the check valves, or even the bubble counters.

If I was having the problem you are, I would disassemble the entire manifold and put it back together piece by piece checking functionality. I would take the end section and put that on first using a bubble counter that I knew was working. If that worked, I would add one of the next sections that I knew worked and test it. Then add the 2nd section that wasn't working with a bubble counter I knew was working and test it. Then finally add the last section and test it. It's the only way you're going to find the blockage.
