Great Pump
This is the second pump that I have had the first performed flawlessly behind the scenes do that I was totally unaware that it was there. It just did what it was supposed to do. I love it.

Great Pump
Installed similar model (can't tell because it covered in gunk) in 1999 and just starting to run a bit questionable. Never touched it since installation. It's basically surrounded by 2-3" thick sediment (sand). Hate to touch or replace something that's worked so well but might be time...Will be this model!!
