Decrease in Mag pump output...
 

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)?

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.
