Would anyone know where I could get replacement brass elbow adapters that go into and out of the steam thermoblock for the Sunbeam EM6910? Just seems too expensive to have to buy the whole thermoblock. My brass adapter from the steam pump into the thermoblock is leaking quite a bit. Thinking that it was the brass tubing, I replaced that with a new one but it's still leaking quite a bit. Not even plumbers tape quite stop the leaking. My thermoblock itself is fine (after descaling and cleaning it out) and now pumps out a healthy amount of steam again. Thanks.
