Loss of pressure

Kegging
#1

I’m new to kegging so forgive my: improper terminology and general ignorance to kegging.

I’ve kegged 2 batches since purchasing my kegging gear. My first was a 5 gal kit that I went through fairly quick since it was so tasty… maybe a month total. My second was a Hefeweizen that was good for its style but i’m not huge on them. This brew moved pretty slow, three months or more. When I went to get some the other day, my gauge on my Co2 tank was zero and my keg had zero pressure. Obviously a leak. Question is, where is the most common culprit for leaks? Any suggestions on how to “leak proof” my system? Any suggestions are greatly appreciated.

Correction, keg had a small amount of pressure left in it.

#3

Check all connections and the lid on the keg, uses star san it should bubble where there’s a leak

#4

Food grade lube on your o-rings is a good idea to.

My recommendation is to get good at detecting leaks first, then get good at fixing them.

Star san in a spray bottle, or just applied with a clean small paintbrush (the kind you’d use to paint a picture, not a barn) on every joint. Keg Lid, both poppets. Grey Disconnect (inside and outside), beer nut/line, regulator connection/line connection, regulator/tank connection, and anything I might have left out. If you suspect there’s a leak, gas the beer and then shut off the gas (at the tank) overnight. If the next day, the keg is flat, then you have a leak.

Thanks everyone. I did use food lube. Looks like a star san bubble test is in order. Question: do any of you bubble test your every time you keg?

#7

You should be able to find silicone grease in the faucet repair section of your favorite home improvement store. That grease is used to lubricate faucet components and is food-grade. Use that on any leaky o-rings or poppets.

No, but when I started I did. Do a few batches and you’ll know when you’re ready to jump.
