Help! CO2 leak troubleshooting

Last weekend, I assembled my kegerator. My old set up was CO2 tank, single regulator, 1 keg, picnic tap. My new set up is CO2 tank, dual regulator, 2 kegs, SS tower with Perlicks (sweet!).

Unfortunately, I have a leak. I have sprayed Star San solution on every air connection (tank-regulator, regulator-airline, airline-connector, connector-keg) and also around the top of the keg. No bubbles anywhere. Ugh! Visually, there is nothing clearly amiss. Audibly, I cannot here a leak. The leak is fairly quick, draining a CO2 tank in under a week.

Ideas on how to proceed from here? It's killing me not to enjoy the new kegerator and the new recently kegged Golden Ale.

Thx.

Check with your local gas dealer. They make a leak detection compound that is a lot better than starsan for finding little leaks. You'll find it.

I had a leak that drove me crazy! This website really helped: Checking for Co2 Leaks

Good luck!
