We’ve lived in a home in Gilbert AZ with a fully automated pool/spa for eleven years. Recently we looked at a home with a pool/spa that was built in the year 2000. It is totally manual operation with a sand filter and three separate pumps for the pool, spa, and a waterfall. Would it be possible to scrap all of the equipment in favor new? I’m not sure with the underground piping all going to individual pumps. I currently have a 3 hp VS pump and was hoping that would work to control everything in this pool.
