Return Pump

Dont know much about dolphins, but Ive owned several different types of Mag pumps and have never had a problem with them. Go mag, you wont regret it! Thats just my 2 cents though.

My problem with the Mags ( unless they have fixed it in recent years ) is the to get to the impeller, the housing used screws into plastic threads. Those plastic threads can get stripped over time, and it you overtighten your toast. For smaller pumps, I prefer o-rings ( no screws ) over screws into a plastic housing.
