Professional 20″ Jumbo Housing Head with 1″ High-Flow Ports
This Replacement Filter Housing Head is the industrial-strength standard for large-diameter “Big Blue” filtration systems. Whether you are repairing an existing setup or building a custom whole-house filtration system, this head ensures a reliable, leak-proof connection for your high-volume water needs.
Key Features & Benefits:
-
High-Volume Water Flow: The extra-large 1-inch ports allow a greater volume of water to pass through rapidly, preventing the pressure drops often seen with standard 1/2″ or 3/4″ heads.
-
Pressure Release Technology: Equipped with a red Pressure Release Valve, it allows you to bleed out trapped air before changing cartridges. This makes the jumbo filter bowl much easier to unscrew manually during routine maintenance.
-
Industrial Strength Construction: Manufactured from high-impact, UV-stabilized polypropylene, this head is built to withstand pressure surges up to 120–125 PSI.
-
Broad Compatibility: Perfectly fits all standard 20″ x 4.5″ jumbo sumps (Big Blue) and supports a wide range of media, including sediment, carbon block, and GAC cartridges.
Typical Applications in Sri Lanka:
-
Whole-House Main Line: Ideal for main entry points where a high flow rate is required for multiple taps and showers.
-
Commercial & Industrial: Used in RO plant pre-treatment, car washes, and restaurants to handle large-scale sediment removal.
-
Specialty Filtration: Suitable for borehole water filtering, aquaculture (Koi filters), and agricultural irrigation systems.
