So, I should've asked my question BEFORE going ahead and backflushing, using a handle from my Astoria Machine... BAH!
Here's what I've done... I put in the backflush and pulled down the lever, then released it back up. I let a few seconds pass, then went to twist off the handle- and woah- pressure! It spit water, the o-ring and the filter out of the machine.
What is the correct way of cleaning out a lever machine? (I purchased this machine 2nd hand and it didn't come with it's own backflush plate or manual... I will try to download one now.)
