Hi. Good to see this site. I have a Pentair Pinnacle 1 1/2 hp single speed pump that old owner left to replace bad pump with. Before I replace it, wanted to know if it would really be worth it to change the motor to a dual speed? Checked on-line and the motor would probably be as much as the cost of the single speed! Can you replace this motor for Pentair with good results and is there a reputable company out there? Read a lot of the good of dual speeds on Pool Forum. I have a 16 x32 in-ground vinyl with a portable hot tub so the hp is correct.
