Good to know. Maybe I assumed it took more CO2 since it takes longer.

You do have that little washer, from tank to regulator?

Thanks for all the input. As I was getting the CO2 tank filled at the LHBS, they mentioned that the keg in and out posts may have a slightly different diameter on my ball lock kegs and that might be the cause of the leak, if I have them the wrong way round. Is that normal, if so how do I know which is which, apart from checking their diameters?

Yes I have the regulator washer and a spare. It does tend to fall out whenever I remove the regulator, so it is not very snug in the lock nut.

Gas in are the ones with notches. See arrows.

Well I finally got around to checking for the leak. I submerged the keg so that both beer and gas connections and lid were submerged for at least 1 hour and set the pressure to about 20psi. I was hoping to see a stream of bubbles, but saw nothing. That leaves the CO2 tank, regulator and hose connection to the CO2 tank. I made sure the regulator O’ring was in place and the nut was tight.

To test the regulator,I tried making a cup with duck tape to hold some star san to see if that was where the leak may be, but I could not get a good seal around the hose, and the star san leaked out.

One thing I have not yet tried is to turn the CO2 on with just the regulator attached and leave for a week or so to see if the CO2 volume drops, but that means no homebrew for a while.

So does anyone have any more ideas of testing the regulator, hose connector or tank for leaks.

Thanks
