This may be old news to some, but... I went on the recommendation of my local supplier and installed 2 Cal Pump 8000 underwater pumps - on two separate water features. The first one lasted 11 months and was replaced under warranty. The second lasted 13 months and is now a decent tarp weight. My advise, stay away from all things Cal Pump. Until they get some decent R&D, quality control and a better warranty we will not be using them. I'm a little gun-shy of my supplier's advise at this point. They are pointing me towards the Matala line of submersible pumps, specifically, the MKH - 400. Does anyone have a thought these pumps?
