Lots of controversy on the subject of backflushing for sure.
One thing about the solenoid drain is the fact that the liquid is draining, NOT going into my cup, so however nasty it is, I won't be drinking it.
I'm always amazed at how much gunk comes from behind the grouphead when removed and normally soak it then brush it real good at least once a month.
Good points about keeping extra gaskets, and I should probably do that.
I ordered the stuff to backflush, so I am going to do it, but if my Gaggia dies an early death, you guys owe me an Oscar or something.
