Anyway, I have a Saeco espresso machine in my kitchen that I like an awful lot, but it'd been really irritating me lately. The steam wand was kind of loose, and it was dripping/leaking a bit when brewing shots. Since I had a bunch of tools out on the kitchen counter anyway, I cracked open the espresso machine to see if I could find where it was having problems. Turns out there's two sets of o-ring seals inside on the valve from the boiler to the head. One is for the wand (a dynamic seal so you can pivot it) and the other was for the steam on/off dial (threaded shaft which makes kind of a plunger valve to route the steam to either the wand or the head.)
I found a couple of suitable o-rings in my stash of viton rings in my reg toolbox and changed out the two seals, which, much like the reg seals in the second stage that I rebuilt tonight, were looking kind of grungy. I also gave the metal parts a quick dip in the vinegar bath of my ultrasonic to clean off the corrosion before I put the thing back together.
While I was working, Heidi came by and asked what I was doing... I answered, "I'm making the coffee maker nitrox compatible..."

I _really_ am looking forward to getting in the water next week...obviously I've been on the surface too long.
