Unlike bars, homebrewers usually don't pull pints all day long every day. And there's enough residual sugars in beer that if it dries it's like cement. That's a bad combination right there.
Rear sealing faucets have all kinds of hardware bits exposed to the air - after they've been bathed in beer. If that doesn't get rinsed out by another pour, it hardens, and the next time you pull the tap handle you're lucky if it doesn't break off.
Indeed, just this evening a new thread was started to that effect: a rear seal faucet used just-not-frequently-enough to keep from seizing up, and the owner was breaking tap handles.
Forward sealing faucets leave very little of the inner workings exposed to air between pours. Further, if you've ever looked at said workings on the newest Perlick models, they are profoundly simple with really just one moving part.
And the only working part of the faucet that is exposed to air is the outside edge of an O-ring and the closing ball connected to the faucet lever. Even if that interface were to glue up, there's very little surface area involved with one face being rubber, so it's easily popped loose.
Bottom line: these things really work, and the more faucets you have, the easier it is to justify them. I have six 525SS faucets and love 'em...
Cheers!
