I have an MJ1200 which seems to make quite a bit of noise. It is new and it make a humming sound which is kinda annoying. Does anyone else who uses an MJ1200 have this same sound? I have used MJ900 and those are quiet. I don't know if it's just mine or if all the MJ1200 do this.

I would say it is just yours. MJs are pretty quiet bullet proof pumps. Have you reset the impeller? If it still is making noise take it back, there is an issue with the pump.
