Our 3/4 Hayward power-flo kicked the can after about 10 years. You could literally hear the thing from a mile away it was so loud and was losing power daily. I picked up a 1 HP maxi-pump from a local pool store for about $270 (after tax). Model number AC 1000mxv. The new pump however is barely moving any water. I don't understand what could be wrong other than it is just a bad motor. It has higher HP and a higher GPM than our old pump, but is barely working at all. Is it just a horrible brand or what?
