20″ Big Blue Water Filter Housing – Taiwan Double O-Ring

The 20″ Big Blue Water Filter Housing – Taiwan Double O-Ring is a premium-grade cartridge housing designed for large-capacity water filtration setups. It supports standard 20″ × 4½″ cartridges, allowing serious flow rates and heavy sediment load capacity. Built in Taiwan, this model features a double O-ring seal for enhanced leak protection and durability. As a result, you get a reliable housing choice for whole-house systems, borehole installations, pre-RO protection, or high-flow filter banks.

Key Features

Standard Cartridge Compatibility: Accepts 20″ × 4½″ filter cartridges, giving flexibility across sediment, carbon block, or specialty media.
Double O-Ring Seal: The dual seal design offers improved leak resistance over single-O-ring models—great for high-pressure or long-service installations. filtershop.co.za+1
Taiwan Manufacture: Build quality from Taiwan ensures reliable materials and good manufacturing tolerances. kingbird.com.tw+1
High Flow & Heavy Duty Use: The jumbo 20″ size and robust construction mean fewer housings needed for large-volume systems—reducing install cost and space.
Versatile Application: Suitable for whole-house residences, farm boreholes, industrial pre-filtration, rainwater harvesting systems, and RO feedwater preparation. easywatersolutions.co.za

Why Choose This Housing?

When you need large-capacity filtration with durability and low maintenance risk, this 20″ Big Blue housing stands out. The double O-ring seal gives you extra confidence against leaks and long-term service. Because it supports standard large cartridges, you keep filter change costs down and spare parts easy to source. Also, it’s built in Taiwan, suggesting strong material quality with good resistance to stress common in high-flow systems.

Installation & Maintenance Tips

Install the housing vertically, with the cap at the top and enough clearance above to remove cartridges easily.
Use a sturdy bracket or mounting plate to support the filled housing’s weight—especially in whole-house or borehole systems.
Before closing the cap, lightly lubricate the O-rings with suitable food-grade silicon grease—this helps ensure a good seal and easier future servicing.
When servicing, use the pressure-relief button if the housing includes one, to make unscrewing easier and reduce the risk of cartridge splash.
Replace filter cartridges according to local water quality (e.g., sediment filters every 6-12 months, carbon blocks as required). Also inspect the housing body—if cracks, clouding or fatigue appear, consider replacing the housing itself.
After change-out, check for leaks and verify expected flow and pressure drop across the housing.
