Description
iSpring WSP50SL-ARJ-BP Whole House Jumbo Spin-Down Sediment Filter with Siliphos®, Auto Flushing & 4-Mode Bypass
The iSpring WSP50SL-ARJ-BP is iSpring's most advanced jumbo reusable whole-house spin-down sediment filter, combining high-capacity sediment filtration, Siliphos® scale protection, automatic self-cleaning, and a built-in 4-mode bypass valve into one premium prefiltration system. Designed for both well water and municipal water supplies, it helps capture sand, silt, rust, dirt, and other large particles while helping reduce scale buildup and corrosion before water reaches your home's plumbing, water softener, whole-house filter, or reverse osmosis system.
Key Features & Benefits
• Four Functions in One System – Combines reusable sediment filtration, Siliphos® anti-scale protection, automatic flushing, and an integrated bypass valve to simplify whole-house water treatment.
• 50-Micron Stainless Steel Filter Screen – Captures sand, dirt, silt, rust, pipe debris, and other large particles before they reach downstream filtration equipment, helping extend filter life and reduce maintenance.
• Siliphos® Scale & Corrosion Protection – Helps reduce limescale formation while minimizing corrosion inside plumbing, fixtures, and water-using appliances. This system helps prevent scale—it does not soften water or remove hardness minerals like a traditional salt-based water softener.
• Built-In 4-Mode Bypass Valve – Easily switch between Filtration, Bypass, Backwash, and Shut-Off modes without disconnecting plumbing, making maintenance and servicing faster and more convenient.
• Touch-Screen Automatic Flushing – Choose Auto, Semi-Auto, or Manual flushing modes using the HD touch-screen controller. Automatic flushing can be scheduled to help maintain peak performance with minimal effort.
• Oversized 1-Gallon Housing – Jumbo-capacity housing holds significantly more sediment than standard spin-down filters, making it ideal for homes with heavy sediment loads and reducing cleaning frequency.
• Flushable & Reusable Design – The stainless steel filter screen is designed to be cleaned and reused instead of replaced, helping reduce ongoing maintenance costs.
• High 25 GPM Flow Rate – Supports high-flow residential plumbing systems while maintaining strong water pressure for larger homes and multiple fixtures.
• Heavy-Duty Construction – Features a lead-free NSF/ANSI 372 certified brass head, clear impact-resistant housing, and corrosion-resistant stainless steel filter screen for long-term durability.
• Protects Downstream Water Treatment Equipment – An excellent first-stage filter for whole-house filters, water softeners, UV systems, and reverse osmosis systems by removing large sediment before it reaches finer filtration stages.
