I have had nothing but problems with the SHellback pump that was in my home when we moved in 10 years ago. I had to replace this pump 2 times now, and had it in for repairs twice as well. They are very smooth talkers at this place. This last time charging me 75.00 for a cleaning. This pump not only does not work well, it is expensive to maintain. I recomemed going to Home Depot and getting a more dependable pump for less. Don't be fooled. The next time I have problems ( and I anticipate it ahead) I will dump this and get something that works!
