I finally got the last pump installed. Made an 11" hole in the floor (which is about 3-4" thick).

Started pulling out some softball sized rocks out down to about 8" to 10".
Then, I ran into a really big rock. About 80-90 pounds, like a rock watermelon.

It was about 15" across the thin part. No way to get it out of the 11" hole.

Before making to hole larger, I decided to see if I could trim some fat off the rock!
Got down in there with my little 2.5 pound hammer and rock chisel..
Took me about an hour, but I trimmed it down to 11".

Got it out. It was a real PITB getting it out to the backyard.

The bad news, there was an even larger rock under the watermelon..

I hollowed out under the floor around the hole, added the filter (old outdoor carpet),
and used a 5 gal plastic bucket as the insert (drilled 1/2" hole first),
dropped in the pump and float switch. All done.. At last..

I think the sump will hold about 20 gallons total. (Before over-flowing).
The pump should keep the level down to just a couple of quarts.
