I have an old concrete/gunite inground pool. about 25K gallons. The motor is a century HSQ125 (1HP 1.25SF 230V) and the pump tag reads Sta-Rite PE A5D-120L (I think it is an L). 

 

Motor is 5 or 6 years old and it is seized up. I would not mind replacing witha more efficient motor and a new pump, but I have no idea what to buy.

 

I would greatly apprciate recommendations...also, I only have 1 inlet in the pool and have always run my pump 24/7  but I would like to stop that asit is wasteful and not necessary.

 

Thanks!
