I am trying to vision your idea, its sounds like a really good idea, but what pipe would you be connection for it to run outside. Any pictures of this, i like the idea though..
It's just a standard threaded 1" bulkhead - on the outside of the sump is a barbed insert adapter I picked up from home depot and reduced it to 5/8" with clear tubing and hose clamp. The tubing goes into the wall, through my crawlspace into the backyard.
On the inside is one of these:

so if I point it straight up the water line would be at max height, but if I turn it down a little it can lower the water line. Mainly I did this because this is my first
experience with a sump and wasn't sure where I wanted the waterline. This gives me close to 2" of adjustment for the waterline.
If this isn't clear I can snap a pic when I get home tonight...
