Milwuakee regulators. Frustration at its finest.

Hello every one last week I purchased a milwuakee regulator. Thinking this will be the greatest thing in the world I slapped that on my 5lbs tank. Worked wonderfully. Until last night I got home from work I looked at the drop checker and it was blue. So I looked at the regulator and there were no more bubbles coming through the counter. So I stood there swore a couple times and proceeded to remove the regulator and put it back on. Following the directions provided my milwuakee. Get every thing open all is good bubbles come through the counter. But if you let it run for 10-15 seconds the bubble count goes from 1-2 per second to 1 every 10 seconds. I was just wondering if I blew this regulator up already and should I order one ASAP? Am I doing something wrong has any one had this issue before? This will be my last regulator from milwuakee that is for damn sure. Any input or thoughts are welcome!!

Thanks

Tim

Brand new cheaper assemblies tend to have problems with the needle valve. It will take a few weeks to settle in.

i have 2 milwaukee regs on milwaukee ph controllers. both work great. give it some time.
is yours on a controller? if it is, give it a high bubble rate. the controller will shut it off and keep your CO2 stable and steady.

My Milwaukee also does this.

My Milwaukee regulator also has this problem. What will happen is you will turn the regulator knob and the bubbles will come out fairly quickly, but then it seems pressure declines and no more bubbles (or significantly less bubbles) are released. I've solved this problem by turning the regulator knob until way more gas then I want is shooting out, and then turning the bubbles down with the needle valve. What I figure is the solenoid (or another internal process that I don't understand) needs a higher pressure to remain open and allow gas to constantly flow. Try increasing the gas using the black regulator knob, and turning the bubbles down using the needle valve. Let me know how it works.

What's your working pressure at? You might need to adjust it to get a steady stream, word of caution, do it when you have time to watch every few hours, adjust with baby steps unless of course you have no fauna in tank.

regulator output pressure?
types of diffuser(back pressure)?
find out the back pressure, and set the output pressure around 10 psi more than the back pressure.

It takes a little bit time to adjust the flow/bubble rate, you need to treat it as pneumatic system as a whole. when turn on the solenoid, bubble rate at the bubble counter only means how much flow at the moment but you need time to wait until co2 fill(increase or decrease) the rest of the tubings so the pressure and flow rate reach equilibrium, then more finer adjustment of needle valve, wait a little each time you touch the needle valve.
That is why after a desire bubble rate is set, when the solenoid turns on the next morning the bubble rate is high the first 5-20 minutes(depends on individual systems) but slow down to the set flow rate.

So turned out after I posted this it started working again. Not 100 percent but made the drop checker happy again. Came home last night boom bubbles stopped again. So this morning I called milwuakee to see why there products suck. The guy said to take the hose going from the bubble counter on the regulator to my gla inline diffuser. He said to blow in it and if there is back pressure there is your problem. He said that there is dust in the co2 canister that will clog the diffuser making the regulator close off. Turns out the diffuser is clogged up. I found it odd because its only about a month old. So here is my question to you guys. Since its clogged how do I clean it? Am I screwed out of 50 bucks because I bought an inline diffuser with a small micron? Any thoughts suggestions would be nice. Thank you for all your post prior to this!!

First time hearing that excuse.

I doubt it is dust. I bet you could recreate the problems you are having even without the diffuser, and just with airline tubing from the needle valve.

But, let's assume for the time being that the representative's assumption is correct.

It will be difficult to clean an inline diffuser, but you can try forcing some dilute bleach through it.

Oh that is not good. I'm going to mess with it in the morning and see what I can do. There was a slip inside the diffuser when I got it that said specifically not to use bleach on it. But I could be confusing this when I got my atomic diffuser?

super atomizer diffuser require about 30 psi to push through, and about 25 psi as operating pressure(after initial push through).

The regular ceramic disc diffuser is about 5 psi push through pressure.

either case, you can only generate no more than 2 psi pressure difference from your lung.

see if you can contact and tell the guy directly, then let us know how he react.

1. what is the output pressure you set on your regulator?

+1 Try without the diffuser.
If it still have the same problem then we should stay away from milwuakee.

As other's have asked, what is the working pressure? Most of these issues are resolved by increased it and fine-tuning with the NV. Those diffusers need high pressure anyway.

By working pressure do you mean the low pressure gauge? I did not have time to mess around with it this morning best I could do I take a bad picture of it.

If the picture is bad it sits in between 0 and 10 so I would say 5 or six.
