Why Choose This Housing?
If you need a robust, high-capacity housing for your home or commercial water system, the 20″ Big Blue Brass Port variant delivers on performance and durability. The brass ports ensure strong plumbing compatibility and reliability, while the large 20″ cartridge size reduces the need for multiple vessels. Also, the white O-ring seal gives added peace of mind against leaks under pressure. Altogether, this housing lets you combine convenience, capacity, and reliability in one unit.
Installation & Maintenance Tips
- Install vertically, with the cap at the top and sufficient clearance for cartridge changes.
- Use a sturdy wall-mount bracket capable of supporting the full housing weight when filled.
- Before inserting a new cartridge, lightly lubricate the O-ring with food-grade silicone grease to extend seal life.
- Use the included or compatible pressure-relief button (if fitted) to safely release housing pressure before opening.
- Replace cartridges according to your water quality and system use (e.g., sediment every 6–12 months, carbon blocks as required). Inspect the housing body and brass connections regularly for signs of wear or leaks.
- After servicing, ensure all connections are tight and check for leaks under standard pressure.
