So my 3/4 hp motor just went bad yesterday. I had a new 1hp motor and impeller in the wings just waiting for this moment. I replaced the motor and impeller and the seals. My psi has always been around 15. Now its 20. Is this a concern? Would i expect more psi from a slightly bigger pump? The motor also feels hotter than usual. I changed from 230v to 115v per instructions. Any clue what might be going on?
