I have a 22k gal rectangular pool. It has a new Nautilus FNS 36 for a filter, plubing is 1 1/2. I have an older pump and motor, i think original with pool....circa late 70s. the pump is a brass or bonze aquaflo. The motor is intermittently humming, with non start. i think it is a capacitor. I would like to know what I need in the way of a new pump. I have no idea what size the stuff is as the info plate has worn off. The pool stays clean, and I am ordering a new suction cleaner, as it had a Polaris pressure, and did great for leaves, not so good for fine debris. The pool also has two skimmers. Please help!! Alzso where do you get capacitors for a Centurion no switch motor...dual capacitors.
