Hydrotools by Swimline's extensive Sand Filter collection sets the standard for performance at affordable prices. Hydrotools sand filters are meticulously designed to efficiently and consistently filter your pool while optimally conserving energy and complying to new DOE compliance and regulations. This ultimately leaves Hydrotools customers with filters perfectly constructed to promote the cleanest water quality, while providing a quick, simple user experience. Our tanks are carefully molded and double reinforced to ensure a reliable, air tight compartment for filtration action. Sand can withstand approximately 5 years of use before replacement depending on water chemistry and proper backwashing frequency. Sand is not included with our filter systems. The pumps housed by our sand filter combo systems have been upgraded to run on low noise levels, creating a fantastic user experience for our customers. Hydrotools pumps also now far exceed current performance and efficiency regulations. All Hydrotools Sand Filter Combo Systems come with everything you need out of the box. Components include: Tank, Pump, Filter Base, Multi-Port Valve, 3-Prong Plug & Power Chord, and more. Spend less time worrying about maintaining your pool, and more time enjoying it - the Hydrotools goal is to help you achieve more quality time on the water with friends and family.
