Just done the OPV after the stock one was obviously sticking shut and making my pump stop for a few seconds until the puck allowed some flow. I used the heavy duty one by Bellabarrista in the UK as I live here, they made one up for me which is an izzo one with a T piece and an adapter ring in one end. Back cover and internal cover with tank see saw and switch had to come off for access
Points of note, I used teflon tape on all joints but in the end din't tighten them up enough and had minor leaks that needed me to be a bit less shy with the spanners. I worked first with it luke warm. Undid the 3 bolts/nuts that hold the pump in place, took hose off the exit of the Original OPV and pulled it through the OPV side of the machine (right as you look at it from front) this gave me all the room I needed. I have a B2 and all parts came undone with ease. The izzo heavy duty OPV has a large exit on top, I had to improvise a tube to fit inside that I could fit the exit tube onto. No biggie. running it I found a few leaks that is where I had to take it out and tighten all joints. Taking the teflon hose off the opv once hot had me covered in hot water/steam. Not pleasant but it got clothes not skin so ok. The boiler never emptied during any of this so I am inclined to dissagree with that comment. What with leaks and adapting the opv exit it took 4 hours which in my opinion is 3 too long! I'm now showing 9 bar for the first time on my guage, no leaks from opv, I will do a search but can any one recommend a rough guide as to the Bii's pressure accuracy should I be aiming higher or lower, previously I was running at 12 bar on the stock guage and have been happy with the latte's but look forward to trying my first shot in the morning, might take an adjustment or two on my grind to get it right.
