Depends on the MAG...some come with stainless screws (pond pumps) and the other come with screws that won't rust (standard pumps). I think they are just coated in something, but are still stainless....some genious had to figure out the savings by only dipping one set of screws and not all of them.traip93 said:do mag pumps rust? i'm going to be using a mag7 insump on my new skimmer?????? ugggggggggg.......
Yep, that and the already mentioned screw heads..... They usually charge more for the pond version because of the longer cord....JennM said:The only difference is that the pond mag has an 18' cord.
This was from my Danner Mfg. rep. Danner makes the Mag pumps.
