I have a 2.2 hp motor now but use 355188.. do we need to upgrade the whole system with a different diffuser, impeller and mounting plate.. if so what is the set I need for the system? And which ones?

A  Answered on 4/6/2020 by InyoPools Product Specialist Patrick P.

Hi Julie, If you have the 2.2 HP Motor (B855) then you will need to replace the following items. 355270 Diffuser and a 355086 Impeller I'm showing the mounting plate for the 1.5 HP and 2.2 HP would be the same.
