First time pool owner, just got my pool installed last week. I've been trying to do research on how/when to properly use my 2 speed pump. From what I gather,it seems as though the supplied 1.5hp 2 Speed Hayward Power-flo pump is way too powerful for the 19" sand filter. Should I only ever use it on low speed? If so, what's the point of the 2 speed?
It is installed with 1.5" flexible tubing. I realize the flow is limited by that as well. I want to hard plumb it and install some shut-off valves, would I benefit from using 2" pipe or am I still limited by the sand filter? Should I consider upgrading the sand filter to a larger one? I hate to do that since I just got it installed. Or do I just constantly run on low speed? I also have a SWG, so not sure if flow significantly affects that or not.
Thanks for the help!
