New keg king reg keeps dropping 5psi

[doctr-dan]

I hooked up my brand new keg king regulator on Sunday night. Checked for leaks etc.
All seemed good.
Set the pressure to 40psi hit the release valve a few times and rechecked the pressure was settling at 40.
Came out the next morning and it was sitting at 35. Bumped it up again to 40, release valve etc.
Came home agin in the afternoon and it was down to 35 again.
Decided to check for leaks and found a small leak , tightend up the fitting, checked for leaks, all seemed good. Set the pressure to 40 again .
Checked about 3hrs later and all seemed okay.

Came out and checked again this morning and it was down to 35. What the !

A few details
Co2 bottle is 0.82kg full of gas sitting next to fridge.
Keg king mk2 reg brand new
Connected to corny keg which is in the fridge.

Any suggestions?

disconnect the gas from the keg and charge the line up to 40 and leave for few hours to see if it drops, that will eliminate leaks at the keg.

Are you leaving your gas turned on or just getting it up to 40psi and turning the bottle off?

 

[mxd]

what he said

if your turning the gas off the gas maybe absorbing into the beer/water or you have a leak.

40psi :blink:

You beer is most likely absorbing it, and is going to become super mega fizzy

Around 12psi is where gas my beer to and I serve my beer at

Im sure he means KpA boys....

 

[mxd]

40 kpa is nada

 

[QldKev]

Maybe kpa, but 40kpa down to 35kpa is bugger all. I don't think I could tell mine moving that much.

Disconnected the gas from the keg, charged the line and it held pressure overnight so it must be a small leak from the keg. I've been over the keg with soapy spray and havnt sen any though.

I was leaving the gas on.
A friend carbonates his kegs by putting them under pressure at 35-40 psi for 48hrs. This is what I was attempting to do.

No I mean psi. I was attempting to carbonate using the method above. Then drop to 10psi for pouring.

 

[QldKev]

Since you are force carbonating pressure, I would take a guess that the beer is absorbing the CO2 as it will absorb many times it's own volume of gas. At around 10-12psi it will absorb 2.5x it's own volume of CO2. So the pressure will drop as the beer absorbs the CO2, which is all I think you are seeing. Get it gassed up, then drop it back to the serving pressure, and try turning the bottle off, as then the beer shouldn't be absorbing any more gas.

Allowing the keg is already cold, at 40psi I would only leave it on for 24hours to fully carb.

 

[mxd]

as Kev said, if you had a leak and left the gas on over night the bottle would probably be empty.

 

[DJ_L3ThAL]

A regulator should maintain whatever the set pressure is if the gas is not turned off. So I think you need to spray the soapy water up under the disconnect when it is in the post. Also don't forget the pressure relief valve can leak if not on properly.

I'd be worried about losing a whole bottle by doing the above without first being 110% sure you are leak free.

If he's got the gas on the pressure shouldn't move in my experience, sounds like it may be a dodgy reg and creeping.

This is what I thought . I had the pressure on for two nights

Return for replacement if you're certain you have no leaks

 

[beer-head]

Mine does same thing when i set it to 40psi to force carb my kegs, drops to about 35psi the next day. Doesnt really bother me and i havent really looked into it I just turn the gas up a bit to get it back to 40psi

No it won't. I don't know if you saw the bit about the regulator being left on.

If you have leaks you will lose your gas.
If you are carbonating, whether it's at serving pressure or higher, your beer will be absorbing gas. That's what is supposed to happen.

Neither of these situations should result in your regulator pressure dropping. That is what regulators do – regulate pressure.

I suggest a faulty reg. Having said that, most faulty regs go the other way, they creep up
