Mag 9 pump issue

[leheath]

My return pump is a Mag 9 that I bought approx. 1 year ago. In the last couple of days, the output flow seems to be much lower than it was. I checked all the pipes and they are not blocked. I took the pump out, unscrewed the bit that can easily be removed and cleaned everything but there was nothing I could see that would be reducing the flow and output did not increase when I put everything back together. Any thoughts on what else to try?

I thought they had a 5 year warranty? Contact the place you bought it from.

Usually mine slows I just give it a vinegar bath and a brushing with a toothbrush and solves the problem. Is there anything in the tube/pipe leading to your tank?
