Just a mere suggestion but you may want to look at another type of pump. I have a mag 7 for my auto top off and I go through about 5-6 impellers a year. Maybe it is just me but I have had 3 of these all with the similar problem (shattering impellers). Any of the Mag pumps over 9.5 are a little bit different of a design and seem to have less problems.
Just a community service bulletin.
