I used to use a Q. One 4000, but ended up changing over to Mag, because of the restart problem. We have some power panel problems and trip a breaker here and there. With the Q. One having to be slapped around a few times I switched.
Didn't want to have to deal with it; in the event we weren't home for a while! Q. One pumps are good for flow in general but not sumps! In my opinion anyway.
