Greetings all,
Just picked up a used B3 and there's a plastic tube going from the steam boiler to the brew boiler (the fill connection I think) - I'm not sure if this is an original part on the B3 but in the B4 videos on WLL and the parts diagram (
here), it's a copper tube that connects the two boilers.
Is it possible to replace the plastic hose with copper tubing?

There's also a magnetic cap on the B4 that sits on the brew boiler (they say it's used to reduce lime buildup) and it's not on my B3 - can I just stick a magnet there?
Thanks again!
