When it comes to finding pool parts at the best price and availability, TS Pool Supply has not disappointed. I was able to get an actuator at a great price, and recently got a new salt cell at the MSRP price but as quickly as the next day picking it up from their north location in Surprise. I appreciate having TS Pool Supply as an option for getting pool supplies when I need them.
