PPW go out of commission quickly.. I think I know why, it's because it needs a stopper/spacer to stop the wheel / impeller magnet from popping in and out and prolonged rattle is stressing the key way, upon restarting. I try to not turn off my skimmer unless absolutely required.. I asked the manufacterer to consider making a little spacer but no luck, but it may cause the wheel to not start more often, who knows. However performance is GREAT.
Since the WM red demon appears to have longer spokes this should be similar to having a stopper.. Of course this is pure speculation, it can't be worse.
thats what my problem was. they do work great when they are working. i never turn my skimmer off. i have short power outages here for just a few seconds & it stops ppw & wont start back. blowing in airline worked a while. keyway wore out after about 6 months on first & 4 months on second
