?     Asked on 2/5/2020by Karin Kramer

I currently have a Pentair Pinnacle Pump 1 1/2 HP - 342856 and the motor has started to run very, VERY loud. Can you advise me which single speed and variable speed motors would be compatible with my pump as well as which gasket kits I would need to install them? It currently has a Marathon C1246 1.5 HP motor. Thank you!

Hi, Karin. The B2854 (Single Speed) or the ECM16SQU (Variable Speed) along with the Pinnacle Tune Up Kit - GOKIT24 are the components you will need for your model pump.
