My 1 hp Hayward motor died on its 40th birthday! I want to replace the pump and 1hp motor with a new 1 1/2 hp pump and motor but with the new pumps the configuration for the incoming piping would require adding a 90degree elbow. on incoming to the pump and a 45 degree elbow on the out going side. And I'm concerned about the effects the added elbows will have on performance.
