The motor on our pump froze for the second time this summer. Pine needles were in the impeller both times. Unfortunately, we could not get the motor to run after we removed the needles the second time. My question is should we go with a different pump. I find it troublesome that the pine needles were able to reach the impeller. Is this a flaw with the Utilitech pump? We are looking at the Pentair 340042 SuperFlo High Performance Energy Efficient Two Speed 1HP.
