yeh but they cost big money .I wish I could afford them but no way .I either find another pump or buy another harbor freight pump .Whatever chewed the wires on the one I have is making it now use more power than it ever did before .I used the heat shrink wrap around the chewed part but can see with the kill a watt tester that it is using more power .It used to use 150 watts and has worked great since 2010 but since this happened a couple of weeks ago it has been going up and down on the tester ,Goes from 173 watts to 200 watts .Tried cleaning the whole pump out but still not working right .The harbor freight one is on sale 79 dollars and I have a 25 percent off coupon also .It is only 2150 gph but I have a 940 gph pump in there also that only uses 30 watts .Other pump I took over to the other house and that was 2900 gph .Just not sure what is going wrong with the pump .
