Default Help a moron with a goofy regulator, please?

I have a second hand regulator that has always been "weird". It works fine for a while, and then goes kitty whompus. I have a dual primary, and I know the high pressure gauge is inaccurate. Especially since my friend dropped it and broke it. Anyway, both primary gauges work fine at first. Then, on the first one, the pressue creeps up or down. Not a big deal, really.

The second primary goes to my 4-way distributor, and I keep that at serving pressure, approx 11 psi. Today, it seems like no gas is going through at all. I have a quick disconnect on that line. When I disconnect it, some gas does go through. However, when I turn the adjustment screw, the pressure doesn't vary at all.

It's possible that a little bit of water might have backed up into the gas line when I cleaned the taps, but I do have check valves installed, and both primary regulators are "stuck".

It's possible that I'm almost out of gas in that tank, too.

I'm out of ideas, so I thought maybe some of your brilliant minds could point out something obvious to me.

I will get the tank filled in a couple of weeks, and I have my back up 5# tank in the kegerator right now so my beer is still pouring!

you need new gauges if they are not in perfect working order. sounds like the tank could be dead.

Ah! Good idea!

Since the suspect regulator is on my 10# tank, and another (really nice) regulator is on the 5# tank, that would work.

On a semi-related note, the regulator on my 5# tank won't fit on my 10# tank. It needs a longer "stem". So I can't put that regulator on my 10# tank.

I'm probably missing something but it sounds like you're just out of gas. Your kegs are pressurized to your serving pressure and may be what are keeping the lines (all the way back to the reg) at serving pressure. Switching tanks will eliminate this possibility though.

I don't think I'm out of gas, though. I mean, when I take the regulator off, and open the valve, Co2 comes out, and the high pressure gauge reads 400 psi (I know that's not very accurate). It's not hooked up to any kegs any more- I pulled it off yesterday and tried playing with it a little bit.

Oh, well, I'll fill the tank first and then see what happens!

Hey moron, switch tanks and pull the faulty one apart. There very easy to daiassemble and inspect, there's all of 3 or 4 pieces. Maybe a stuck or ripped diaphragm, it's hard to say. It takes almost zero mechanical know how to rip one apart.

This regulator is different looking than my other- it has four phillips screws in the corners, around the bonnet. Should I just unscrew those, and check out the diaphram? It looks like cornelius brand.

You can also get stems at Lowes.

Sounds like a NAD.
