Co2 regulator problem
Hey guys,
Anyone have trouble like I am with my Co2 regulator?
For a long time it's been fine, but lately it's started to creep up on it's own.
I'll back it down again and it will be up a few psi when I see it a few days later.

How has the temperature in the room been? If its been getting hotter then the pressure in the cylinder will increase too.

Good thought but the room temp is stable.

Is the regulator on the inside or the outside of the fridge?

Because when it is inside the fridge, DON'T trust it!

Outside the fridge.
It's been stable for years but now is not.

Could the beer be over carbonated?

It wasn't but is now since the regulator creeped up.
So I shut of the valves to the kegs and turned the regulator back.
I'd wait till the kegs ran low on pressure before turning the valves back on.
Yes I have a valve on each keg Co2 line.
Meanwhile I'd see the regulator psi creep up even when it wasn't flowing.

How many bodies on the regulator? If just one, you might want to inspect it inside. It's not uncommon for a stray particle (usually teflon tape used in it's assembly) to get loose inside and get onto/into the diaphragm that controls the CO2 out pressure. If it's a dual body, and only happens to one body, then that's even more likely the case. It could, also, be that some beer got pushed back up into the body and is causing the issue. A good cleaning inside the regulator body should take care of that. Install check valves before the regulator to prevent it in the future.

BTW, did you get this as a brand new regulator or used? Brand/make of the regulator? I've had best results with Taprite regulators for carbonating/serving. I also have a Leland, but that's used (mostly) to simply push beer from fermenter to serving kegs (or aging kegs).

Sounds like the diaphram in the regulator is leaking. Maybe at one time some beer backed up into it, interfered with the internal seal? If the creep isn't coming from back pressure off the keg then the regulator must be faulty. At this point live with it or do something about the reg. Possibly take it apart inspect and clean, or maybe a rebuild. Worst case scenario new regulator.

IF you can get the rebuild kit for the regulator, yes... If not, then replace. I stand by my previous recommendation of getting a Taprite if you replace it.
