  1. Great pump, discontinued?!? 5 Star Review

    Posted by on 12th May 2018

    I've run one of these CS10-135/4 half horse in my 20ft shallow well every day thru filters for 5 years and it's still going. Too bad it's discontinued, this looks like the last one and it's MINE...

  2. Best pump for low current draw 5 Star Review

    Posted by on 7th Jan 2013

    Great submersible pump. Easy installation and less expensive than most competitors. The lower current draw means lower electric bills.
