Old Silvia Upgraded

I installed this new adjustable OPV on my older (~2005) Silvia, as the old OPV was no longer holding good pressure. I bought the portafilter pressure gauge kit with it and adjusted the new valve for 9 bar. The result is the best espresso this machine has ever made (and it was very good before the original OPV gave out). The only slight issue was that the new OPV tightened into a bad position on the older boiler and I had to use one of the copper washers provided with the new OPV and really squash it to get the angle right.
Shipping for this order was practically instantaneous and deliver was next business day.
Thanks, Coffee Addicts!

Pre 2006 Sylvia OPV replacement

This replacement made a dramatic difference to the quality of my shots. The machine has been on a death spiral for the last year. It was due the the old pump and the OPV wearing out. With these two new parts installed. I have my crema back. The only drawback is the lack of support to discuss technical issue during the repair. I could not find a good video for replacing a pre 2006 Sylvia. This is not an easy replacement and required some creative engineering to get it done right.
