Why do taps stick closed after a few days of no pouring? How do you cure it?
Forward seal faucets like Perlick will fix this problem.
This. Most cheaper faucets are rear sealing, which means when it's closed, the moving parts and mechanism that the beer just flowed over, are now exposed to the air, allowing them to dry out, gum up, and bugs to grow on them. Rear sealing faucets need regular cleaning, and really need to be in continual use (like a bar)
Perlick faucets are front sealing, which means when the tap is closed, all the moving parts are in the beer behind the seal. Therefore theres nothing to dry out, and a simple squirt of starsan up the faucet at the end of a drinking session is all you really need. I've had Perlicks go unopened for weeks, and they pour just fine.
It seems just about everybody buys the cheap ones first, then upgrades to Perlicks. I just tell everyone to buy the Perlicks to begin with.
