Spring has arrived and it won't be long till its time to open up then pool for the season. I want to replace my pump with a 2 speed pump to save on electric. I have a 150 lb sand filter with a Hayward powerflow lx 1.5 HP pump. My question is do I really need 1.5 HP or can I downsize to 1hp? I have been looking around at what others are running and it appears that my filter is small for the size of the pump and others appear to filter much bigger pools with a smaller pump. Since I am going with a 2 speed would it be ok to go with the bigger pump since it will run on low speed for the majority of the time? I attached photos of the data plates on my current pump and filter model number. Unfortunately my pump data plate does not seem to give me the service factor so it is kinda hard for me to compare. Any ideas or advise??? Thanks in advance.
