Description
20″ Jumbo Filter Housing
The 20″ Big Blue Water Filter Housing – Taiwan Clear Housing is a high-capacity cartridge filter housing designed for residential and light-commercial use. Made from transparent, heavy-duty Taiwan-manufactured material, it allows you to see cartridge condition at a glance and fits standard 20″ × 4½″ (≈51 cm × 11 cm) filter cartridges. Because of its size and clarity, it is ideal for whole-house, borehole or under-sink systems where visual monitoring and large flow capacity matter.
Key Features
- Standard 20″ Cartridge Compatibility: Accepts 20″ × 4½″ filter cartridges (sediment, activated carbon, etc.).
- Clear Housing Material: Transparent body lets you view filter status visually for easier maintenance.
- Made in Taiwan: High-quality manufacturing ensures durable plastics and stable performance.
- High Flow & Flexibility: Suitable for whole-house systems or booster-fed setups; supports various cartridge types.
- Easy Service: Threaded top cap with O-ring seal and optional pressure-relief button (check variant) for safe cartridge changes.
Technical Specifications
- Housing Size: 20″ standard length
- Cartridge Diameter: Fits up to ~4½″ dia filter cartridges
- Port Size: Usually ¾″ or 1″ NPT Female (verify on product variant)
- Material: Transparent reinforced polypropylene (Taiwan)
- Max Pressure: ~90 psi (~6.2 bar) (typical for this size)
- Max Temperature: Usually ~4−38 °C (verify specification)
- Colour: Clear/transparent body, compatible with standard head
Why Choose This Housing?
If you want a combination of high capacity, visual clarity and reliability, the 20″ Big Blue Water Filter Housing – Taiwan Clear Housing delivers. Its clear body allows you to monitor cartridge saturation or debris buildup without disassembly. Also, by using standard 20″ cartridges, you simplify maintenance and reduce filter costs. In addition, the high-flow design supports whole-house or borehole systems with fewer housings. This makes it a smart choice for homeowners, service providers and technicians alike.
Installation & Maintenance Tips
- Install vertically with cap up and sufficient clearance above for cartridge removal.
- Use a bracket or sturdy shelf to support the housing weight when full.
- Before inserting a new cartridge, lubricate the O-ring lightly and ensure it seats correctly to avoid leaks.
- To change cartridges, push the pressure-relief button (if fitted) before unscrewing the cap.
- Replace cartridges at the recommended intervals (sediment every 6-12 months, carbon blocks as needed) and switch to a new housing if you notice any cracks or clouding in the clear body.
- After servicing, check for leaks and ensure expected flow is maintained. Clear housings can help you see early signs of bypass or O-ring failure.
