Waveline DC6000 Issues - Is this Normal?

[redfishbluefish]

I switched from a MAG 9.5 as my return pump, to a Waveline DC6000, May 2016. Over eight years with the MAG, with the only issue being that the stainless screws were rusting. In less than two years this Waveline pump has stopped working twice. Never had this issue with the MAG's. It happened again last night some time, finding the DT at 73.1 degrees this morning. As with the last time, took the pump apart and only found an amount of slime in the pump/impeller. Does a little slime cause these pumps to stall and stop working?

This time around I did attempt to simply restart the pump, and it started for about 30 seconds and then stopped. So I pulled it out.

Lucky for me I still have the MAG as a backup, with the pipe and union all set to simply switch out the bad one within a couple minutes.

Am I going to have to put the Waveline on a maintenance schedule for cleaning? I haven't put it back in yet.....pondering whether or not I should go back to the MAGs. I was trying to be more energy conscience, with the MAG being an energy hog.

Paul...I used to use a Waveline DC12000 for a return feeding a manifold. I quickly discovered they really degrade as they get dirty. I actually ended picking up a second one and would simply do a quick swap every 2-3 months. I'd let the dirty one run in vinegar bath for a couple days and it would be ready for the next swap. Just my experience with them.

That's what I was afraid of. And that massive impeller head is a pain in the butt to clean. Had to use Q-tips to clean it best I could. Thanks.
