I have this same problem, though I have not measured a drop in pressure (either on the pressurestat or with an external brew pressure gauge). It does mainly happens if the pump has to work hard, like on a tight slow pour, and it might sqwark (a pretty good word for the sound, BTW!) once total or once every couple seconds for part of the pour. I'm not mechanical, but the frequency and sound make it seem like a sqwark per revolution of the internal mechanism on a rotary pump.
The problem started happened infrequently maybe a year ago and has gotten more frequent since. But part of the trouble in my case is that I just replaced the pump maybe 2 years ago with parts and instructions from WLL. I'm wondering: is it possible that I installed something incorrectly that led to this so soon after replacing? Or does that sound like a bad part? And either way, what to do now?
