I had a flushing problem when I first set up my system and figured out that I had my pipe exits too deep in the sump water.

Hmm, interesting, I"ll have to investigate that further. Currently my pipe does exit into the water, I"ll have to have a go at that. Thanks!

I had a similar problem and drilled a hole in the pipe just above the sumps waterline and the surging problem was fixed. A small bit of water does come out the hole, hence close to the sumps water line to catch the water.
