Low pressure from used keg Suggestions?

Low pressure from used keg Suggestions?

I got two used kegs and filled them with new 5 gallon batches. Replaced most gaskets.

One pours fine. Second does not.

I just switched taps and the problem is not the faucet or that line, but somewhere in the keg itself.

What could be the cause?

Check for leaks:

• lid
• bottom of both posts

Are you using keg lube on all o-rings?

Of course the obvious question is it hooked up to co2?
Next would be possible major leak
then check poppit for debris.

That ^
Excellent point!

Or potentially crud in the dip tube

That is my theory.

No leaks that I can hear or see.

Keg lube on all rings.

That is my theory.

Don't overlook the poppit too.

It's likely a long shot but I've read of it happening: long dip tube slammed against keg bottom. Usually means the tip isn't located in the well made for it...

Cheers!
