Big Blue Filter System 20″ Triple

The Big Blue 20" Triple Stage System is a heavy-duty, point-of-entry (POE) filtration unit designed to handle high flow rates while providing comprehensive water treatment. It is the primary choice for South African users dealing with municipal sediment, borehole impurities, or rainwater harvesting. By utilizing three sequential 20-inch "Big Blue" housings, this system allows for a customizable multi-stage defense, ensuring that every tap in the building delivers clean, safe, and clear water.

Key Performance Features

• High-Volume 20" Housings: Specifically engineered for high-flow applications, minimizing pressure drops even when supplying multiple bathrooms or irrigation points simultaneously.
• Triple-Stage Sequential Filtration: Allows for a "Sediment-Carbon-Carbon" or "Sediment-KDF-Carbon" configuration to target everything from visible dirt to microscopic chemical tastes.
• Reinforced Heavy-Duty Mounting Bracket: Features a corrosion-resistant, powder-coated steel frame that supports the significant weight of the system when fully saturated with water.
• Built-in Pressure Relief Valves: Each housing is equipped with a red "bleed" button, making it easy to release air pressure for simple, tool-free filter cartridge changes.

Ideal Applications

• Whole-House Filtration: Protects your geyser, washing machine, and dishwasher from sediment buildup and chlorine damage, extending the lifespan of your appliances.
• Borehole Water Treatment: The essential first line of defense for South African boreholes, effectively removing silt, sand, and organic odors before the water enters the storage tank.
• Light Industrial & Agricultural Use: Provides clean water for hydroponics, food preparation, and high-pressure washing systems where consistent flow is critical.
• Rainwater Harvesting: Acts as a final "polishing" stage to remove fine particulates and tannins from stored rainwater before it enters the household plumbing.

Product Benefits

• Standard 1" (25mm) Ports: Features high-flow inlet and outlet ports that match standard South African plumbing, ensuring an easy installation for any qualified plumber.
• Universal Filter Compatibility: Designed to accept all standard 20" x 4.5" (Big Blue size) filter cartridges, giving you the freedom to choose your preferred filter media.
• O-Ring Leak Protection: Equipped with oversized, high-density Buna-N O-rings to provide a watertight seal under varying South African water pressures.

Pro Tip: For the best results in areas with high sediment, we recommend a 5-micron pleated sediment filter in the first housing. Unlike standard spun filters, pleated versions can be rinsed and reused a few times, significantly lowering your long-term maintenance costs. Always install a shut-off valve before and after the system to make your 6-monthly filter changes quick and mess-free.
