When I first received the pump it appeared to be cheaply made and I thought that it would not work. The pump body is made of plastic. But, I connected the pump to two 355 watt panels (connected in series), slipped a 1.5 inch PVC pipe (without glue) just to test the pump. WOW! Even with loose fitting PVC pipe, this pump really works. I now have it permanently connected to a DEV60 Jandy pool filter. Pump runs all day and is SUPER quiet. This pump is quiet and powerful. Although I have it connected to a DE filter and it works just fine, I think a cartridge filter would be a better match for this pump.
