Hello there! Does anyone know where I can find an OPV kit for my nuova simonelli Oscar 2 in the USA?

If you don't mind buying parts separately, you can make it the way I did, from ECM Giotto's OPV, which I bought from Stefano's. Other than OPV itself, you'll need a piece of 4x6mm PTFE tubing, two NS 07300364 STRAIGHT 1/8 fittings, one 1/8M to 1/8M BSP elbow fitting, one 1/8 BSP FFF tee fitting, 6mm barb tee, and a piece of 5x8mm silicone tubing. Here's the photo of how it looks (copied below). This is Oscar I, but it pretty much is the same machine.

Once installed, how is the bar pressure? Do you see a difference?

Well, sure, I see that the pressure is now limited by the OPV. I set around 9.5 bar on a blind basket, so it stays up to around 9 while brewing.

So I installed the OPV kit from Elektros, but my machine isn't reading the water tank. Any clues as to why?
