About This [NSF/ANSI 372 Certified] The WSP500ARJ-BP sediment water filter is certified lead-free under NSF/ANSI 372 standards, ensuring safer and cleaner water for your home. [Convenient Auto Flushing] The iSpring WSP500ARJ-BP whole house water filter comes equipped with a built-in auto flushing module featuring dual power supply options. This innovative feature simplifies routine maintenance, saving you both time and effort. You can effortlessly select from three modes—auto, semi-auto, or manual—using the user-friendly HD touchscreen interface. With the auto mode, you can preset a schedule for the system to automatically flush, ensuring optimal performance without constant monitoring. [Bypass Valve Design] iSpring WSP500ARJ-BP provides 4 different operation modes, including filtration mode, shut-off mode, bypass mode, and backwash mode. The bypass valve design can control the water in different channels, making maintenance a breeze. Backwashing, which reverses the water flow, is more effective than regular flushing at dislodging and expelling sediment trapped in the filter mesh, resulting in less frequent manual cleaning and filter replacements. [Jumbo Size and High Flow Rate] Designed for a more complicated well water situation, the WSP500ARJ-BP spin-down sediment water filter provides a 1-gallon capacity, which is 22 times larger than standard sediment filters. The maximum flow rate of WSP500ARJ-BP is 25 GPM. Universal fittings can be easily installed and adaptable to other applications—two types of threads on both ends of connectors: 1-inch MNPT and 3/4-inch FNPT. [Advanced Prefilter for Complex Water Conditions] The WSP500ARJ-BP can filter up to 99% of large particulates such as sediments, dirt, rust, sand, floating objects, and other water pollutants. As a whole house water purification pre-filter, WSP500ARJ-BP is a reliable first line of defense that can protect terminal equipment and appliances, including downstream pipelines, water purifiers, water heaters, wall-hung boilers, washing machines, and showerheads. [Pressure-resistant and Long-lasting Construction] Crafted from 316L food-grade stainless steel, the precision filter mesh in the iSpring WSP500ARJ-BP water filter ensures exceptional durability. The explosion-proof transparent housing not only offers crystal-clear visibility but also enhances user convenience and intuition. This housing has successfully passed rigorous tests, enduring pressures exceeding 500 psi and withstanding over 100,000 water hammer tests, demonstrating its outstanding resilience and longevity.
