oddbean Do you think it would be safe to be shipped? Have you emptied the boilers?
Really no need to empty the boilers, certainly the brew boiler is sealed and nothing can leak out. The steam boiler can have most of it’s water removed, but not all as there “probably” isn’t drain taps on that one. They were introduced on all models about 1 year ago.
The small amount of water left in the steam boiler shouldn’t cause any issues and is mostly retained by the vacuum breaker. If it’s a memory metal one (which some did have), then it’s a positive close anyway and nothing can come out.
