  • Thumbs up for CoffeeParts sponsor on OPV mod

    Hi Everybody,

    I just completed the OPV mod for my silvia last week and CoffeeParts has been really helpfull even if it involved a simple gasket.

    For those interested, the guidelines are here: http://mysite.wanadoo-members.co.uk/...essureMod.html
    But its better to use a teflon gasket instead of a copper one. Reason is, the gasket would compress as you tighten giving variable thickness

    Call Coffeeparts, they know now which part to use and you get 5% discount when coffeesnobs is mentionned.

    Cheers,
    Laurent

    I have been considering doing this mod for some time :-/
    What are your thoughts on ease of the mod and the effect in the cup?

    Cheers

      Hi Dan,

      Effect in the cup: a bit sweeter and the sometimes bitter aftertaste has gone. Bizarely, I have to grind 2 clicks finer now on Rocky.

      Mod very easy to do, although it can be a challenge after a few trials and the machine becomes hot. Specially when hot, remember to open the steam wand to release pressure or youll get vapor and water all over when unscrewing the OPV.

      Overall, its a good improvement but did not revolutionize my ristrettos. Maybe its better for the pump longevity.

      Cheers,
      Laurent
