Default Cant find leak

Beer gets and stays carbonated but a 5lb tank is lasting only days. Full fill started at 850psi, quick carbed now down in the red after only 3 days. I did the soapy water test on the connections but saw no bubbles. my first tank kicked before a 3 gallon keg. WTF?

fill your kettle take the tank (on) and regulator in it head first, if you don't see bubbles you just eliminated that leg.
next check the distribution manifold and eliminate that leg.
then take the keg and put the top in the water.
if there is a leak you should find it.
most leaks are at the regulator to tank or o-rings on the keg

Still nothing. Could it be the beer distributor not filling it all the way? Not like they have any way of checking, it's done when the larger tank stops hissing. Usually only takes 5 seconds.

The tare (empty) weight of the tank should be stamped on it, so you can weigh the tank to determine how much gas is in it. So, at the least, next time you get the tank "filled", weigh it.

As for the leak, the suggestions already provided are sound, and they cover everything from CO2 cylinder to keg...

Cheers!

just for reference, my 10 lb fill lasts right at 6 months and LOTS of kegs. there's a problem with the connections somewhere

my 5lb bottle is lasting 2-3 months, carbing and serving 5-6 kegs. I think I've a leak somewhere but can't find it.

It's been recommended to check the chimes, but I have thusfar been too lazy to do so.

Also for reference. My tank is in the red as soon as it gets cold in the fridge.
Make sure it is actually empty.

Easy way to locate leaks in your system...

Charge the entire thing to ~30 psi, and listen...
If no hissing sounds, pull the gas locks from the kegs and turn off the tank.
Check the regulator an hour later. If it's not moved, check it again in another hour, or in the morning. If both gauges haven't moved, you're leak free (24 hours is the ultimate test).
Every time you alter your gas configuration, charge the entire system to ~30 psi and listen. Then turn off the tank valve and see if the high pressure gauge starts dropping.

If you keep the tank in the fridge/freezer, the high pressure gauge will read lower. It will still dispense the same amount, you'll just get a lower reading on that side. I keep my tank out of the fridge (more room for kegs that way).

I did have some leaks that the above methods helped me to hunt down and eliminate. I had to tighten up the worm clamps on the gas lines to eliminate them. Not a big deal, just be careful to not go too far there.

I used the same method on the 20oz tank and regulator setup I have (charged to 30psi and waited).

I would also make sure you have the small plastic items on any manifold fittings you have. Unless they're tipped so that you don't need those of course. I quickly discovered forgetting to use one of those the last time I altered the setup. Easy fix, just gave me face-palm...

If I'm losing a full tank in three days shouldn't the leak be obvious? Also, is there something I shouldn't put under water to fond the leak? Everything was purchased from Keg Connection pre assembled.

You can put the gas locks under water to see if you have leaks either from where they connect to the posts (the fitting there) or at the hose clamp side. Charging the system and turning off the tank (with the gas locks off of the kegs) will help. I ended up turning off manifold valves to ensure they were leak free one at a time. You can also shut off the manifold valves to see if the leak is before, or after, the manifold...

On a positive note, once you find, and eliminate the leak, you shouldn't need to worry about it again for a long time. Or until you change the setup/configuration.

BTW, I couldn't hear any leaks at serving pressure (10-12psi). But when I cranked it up to about 30psi, you could hear it leaking...
