Why Choose This Housing?

When you’re looking for a robust, high-capacity filter housing for your whole-house water system, the 20″ Big Blue Double O-Ring housing delivers both performance and peace of mind. With its large cartridge size, you get fewer changes and lower maintenance. Additionally, the double O-ring seal enhances durability, especially in systems exposed to lots of pressure variation or heavy sediment loads. All in all, it gives you the flexibility of standard cartridges with the durability required for serious filtration applications.

Installation & Maintenance Tips

Install the housing vertically with sufficient clearance above the cap for cartridge removal?
Use a sturdy bracket or wall-mount rated for full housing weight when filled.
Lubricate the O-rings lightly with food-grade silicone before inserting the cartridge and re-sealing.
Press the pressure-relief button (if included) before opening for safe cartridge changes.
Replace cartridges at recommended intervals—sediment every 6-12 months, carbon blocks as needed. Inspect the housing body periodically for signs of cracking or UV damage.
After service, check for leaks and confirm flow meets expectations.
