I have an extreme power US 19 inch sand filter with a 1.5 hp motor. I need to replace my motor and what I would really like is a pump motor like was on my last sand filter which was an Intex 16 inch with a .75 motor. The reason I really want a pump motor like the last one is because it had a three-way toggle on off switch. (on/off/timed.) and it had an air release valve at the top of the strainer. I would like a pump with the increased horsepower, 1.5, but I would like it to have the features of the Intex pump motor I had. The on off switch is non-negotiable. Does anyone know who carries this. Also, any ideas or input would be welcomed. Thank you.
