So yes, I’m thinking that perhaps you have a combination of hardened gaskets, and maybe weakened springs, both of which could cause loss of pressure during brewing. It’s a snap to replace all of that; while you’re there, I’d do the seals on your lever too (with some food-grade silicon grease) and also look at wear on the cam (likely is fine, but since you’re going to have it out anyway). I’d be stoked for you if this is the solution! best, bmc > On Apr 13, 2018, at 08:56, Eric Christoffersen <zakt...@gmail.com> wrote: > > Yes!
