I bought the SVRS option on my Hayward EcoStar and found it to be incompatible with my 2nd floor roof mounted solar panels. When the solar system would start, the pump would see priming the solar panels as an entrapment event and trip for 24 hours. You don't have solar, but, that waterfall pump (depending on how it's plumbed) may trick the SVRS. I don't know but it's something to consider.
