Decrease in Mag pump output...

[Quinn]

My Mag12 has been running for about nine months. Any reason why the output would have decreased? I thought the piping might just be slick and therefore less output turbulence but it is sucking in noticeably less water these days. I clean it regularly.

Any chance something is stuck in the piping?
(obvious question I guess), any chance that some gravel/sand got into the impeller assembly?

My mag7 on my skimmer just stopped working.

I had to turn it on and off a couple times in a few minutes. It didnt seem to like that.

I cleaned it just over a month ago.

I assume it doesnt like being turned on and off?

I should probably check the impeller. I just remove those four main screws right (I think there are just four)?

[BCOrchidGuy]

Yes that's all there is too it, when you're replacing them make sure you don't over tighten them though, that's just pastic they are going into.
