Description

20″ Jumbo Filter Housing

The 20″ Big Blue Water Filter Housing – Black Housing is a heavy-duty cartridge housing designed for high‐capacity filtration systems. The black polypropylene body accepts standard 20″ x 4½″ (≈51 cm × 11 cm) filter cartridges, enabling whole-house or commercial flows with ease. Because of its oversized capacity, it reduces pressure drop and requires fewer housing changes compared to smaller models.

Key Features

• Standard 20″ Cartridge Compatibility: Accepts most 20″ x 4½″ filters (sediment, carbon block, etc.) for flexible use.
• Large Port Size: Common 1″ NPT female ports enable high flow with minimal restriction.
• Heavy Duty Housing Material: Durable polypropylene body in black finish offers longer life and better UV / sunlight resistance than clear housings.
• High Capacity & Versatility: Ideal for whole-house systems, borehole filtration, pre-RO protection or large single-cartridge setups.
• Pressure Relief / Serviceable Design: Many units include a pressure-relief button or bracket mount for safer servicing.

Technical Specifications

• Housing Size: 20″ standard (20″ length sump)
• Cartridge Diameter: Fits up to ~4½″ dia cartridges
• Inlet/Outlet Ports: 1″ NPT (female) typical for black housing variant
• Max Pressure: ~90 psi (~6.2 bar) in standard usage
• Operating Temperature: ~4–38 °C for many models
• Colour: Black body with compatible head/cap

Why Choose This Housing?

If you’re configuring a whole-house or high‐flow water filtration system and you want reliability and simplicity, this black Big Blue housing stands out. It allows you to use standard large cartridges, making maintenance easier. Moreover, the black body offers enhanced durability and better aesthetics in mechanical rooms or visible installations. Additionally, because it’s a single large cartridge housing rather than multiple smaller ones, you save space and simplify service intervals.

Installation & Maintenance Tips

• Mount vertically with the head above the sump and provide clearance above for cartridge changes.
• Use a wall-mount bracket or shelf capable of supporting the filled housing weight.
• Before inserting the cartridge, lubricate the O-ring lightly and ensure it seats correctly to avoid leaks.
• Use the pressure-relief button if present, before unscrewing the cap to ease opening.
• Replace cartridges as required (e.g., sediment or carbon) and inspect housing body for any signs of cracking or UV damage—black housings tend to resist UV better than clear models.
• After service, check for leaks and verify flow meets expectations; if flow drops, check cartridge condition or port restrictions.
