Pool pump

My Hayward RS replacement series pump stopped working 1.5 hp can I replace with a 1 hp Pentair superflow pool pump. Or do I need a1.5 hp Pentair. Pool is 18x36 approximately 30,000gallons

My suggestion would be to stay with the 1.5HP. However, if you want to go with something more energy-efficient, we recommend a variable speed pump. What is the service factor (SF) of your current motor? That rating should be listed on the motor specification label.

1.5

That would mean that your current pump has a total HP of 2.25. I’d recommend looking at the Waterway Power Defender 270. That is a 2.7HP variable speed motor. Click Here to View More Details on the Waterway Power Defender 270
