One thing I must say...persistence pays off when ordering these "hard to get" Breville parts.
Bob, check you inbox in the next hour or two...
In the meantime, both of you guys appear to have suffered with "the black ball syndrome". I'm still mulling over Brendan's experience with a pitted ball, and comparing with the ratty old ball valve from an ancient -900 that was donated to me as a hopeless leaker... even that ratty old thing, the ball inside it was not pitted and black. It was certainly darkened in the area that gets impinged by the steam. But it wasn't badly pitted and it was only that area. It didn't look nearly as bad as Brendan's ball. And after a year running with nothing but flipped seals, it's still going strong. The nice new ball valve that came with my mid 2018 -920 is sitting in a shoe box unused because that old -900 valve is still leak free.
Anyway, re "black ball syndrome"... Brendan, have you been using Pavlis water the whole time with that ball? Or did you use plain distilled or RO for a while. As you correctly fingered, overly pure water doesn't want to be, so tries to pull stuff out of the metals... causing pitting and wear. That is why we add buffering ions to distilled water. It makes the water happy, which then makes our machines happy. Anyway, is it possible that the "black balls" out there have seen some overly pure water or water with chloride (which is not chlorine) above say 30ppm?
Funny side story for Canadian Brendan: Before we figured out how to rebuild these valves, I bought not one, but TWO spares. BOTH from Forum Home Appliances in... Canada. I think
I bought the last two they had. They said "two in stock", I bought both, then a week later they were no longer listed.
