Once I had a leak in my system that I couldn't seem to locate.

It turned out I had a bad regulator. I was able to get a rebuild kit and that corrected the problem.

Leaking regulators can be difficult to find using star-san or soap solution.

To find the leak, I hooked up just the regulator to my bottle and plugged the low pressure outlet port.

I cracked the tank valve and set gauges to 15 psi. Then I closed the tank valve and waited.

A good regulator will hold pressure on the gauges with plugged outlet.

I had the same issue with my kegs. Come to find out that something inside my regulator was leaking. I took off all the gauges and re taped all threads and put it all back together and it is now holding pressure great. So look into rebuilding your regulator.

If that's the case I'm calling kegco as this is a brand new regulator that came with my kegerator. Maybe I'll call tomorrow and have them send me a new one just to be safe

You may want to try the regulator test I suggested earlier before calling them.

You should confirm that the regulator is leaking before just randomly replacing parts.

By low pressure outlet port do you meant the gas lines aka just turn the valves to the "off" position so no gas runs out?

That would work if you know for a fact that the valve doesn't leak when it's closed.

Ideally you would disconnect the valve from the regulator and plug the opening in the regulator with a 1/4" threaded plug.

That way you rule out any issues with possibility of the valve leaking.

Sounds like a plan. Thanks for the tip. If that holds, I'll replace the valve and take it one connection at a time

I had a similar problem and it turned out to be a missing flat washer between the regulator and the gas bottle. It was mentioned in an earlier thread but it's a great place to start your systematic check one connection at a time.

I'm paranoid so I tend to use teflon tape on the threads of my tank where the regulator screws on. I figure it can't hurt and may likely help.

TMK:

The gasket provides the sealing function at that connection as they are not pipe or flare threads.

Teflon tape should only be used on pipe threads. Pipe threads are cut such that they become shallower moving away from the pipe end. The threads actually seal themselves as they are tightened. The teflon tape acts as a thread lubricant so that the connection can be tightened without any gauling. It's really not meant to be a sealant.
