Look at the amount of rust I got out of the block. Each picture is the amount of rust from that flushing. I dumped the water about 7 times before no more rust was coming out.

Tom, were you flushing with vinegar here, or just straight water?
I usually just use a water hose, but I like the sump pump idea. Thanks for posting the pics.
