Upflow Filter 12x48 w/ Bypass 3/4"

The Upflow Filter 12x48 with 3/4" Bypass from Water Softener Plus is a versatile whole-house filtration platform designed for flexible installation in either up-flow or down-flow configurations. Built around a durable 12" x 48" black polyglass mineral tank, this system gives installers and homeowners a configurable foundation that adapts to a wide range of water-treatment needs and media types.

Configurable by Design

The defining feature of this system is its adaptability: simply reversing the inlet and outlet connections switches it between up-flow and down-flow operation. Up-flow configurations are popular for media that benefit from natural bed expansion and reduced channeling, allowing the media to lift slightly and clean itself with the flow of water, while down-flow remains the conventional, well-understood approach for many applications. Having both options available in a single platform is a genuine advantage, letting you match the system precisely to your chosen media and your specific water chemistry rather than buying separate hardware.

The system arrives as a complete hardware package ready to load with the media of your choice, which means you can target your particular water-quality concerns, whether that involves taste and odor, sediment, or other contaminants. It is packaged for convenient parcel delivery, making it easy to ship and handle even in tighter spaces.

The included bypass valve makes future servicing simple, letting you isolate the unit while keeping water flowing to the home, so a media change or maintenance task does not mean shutting off water to the whole house. The upper basket and gravel under-bed come included to support proper media bed formation and distribution, and the C-Series in-out head ties everything together in a compact, reliable package.

With its quality polyglass tank, flexible in-out head, and ready-to-go internals, this upflow filter system offers a practical, customizable base for whole-house treatment. Choose the media and plumbing adapters appropriate to your situation, and you will have a tailored filtration solution built to your exact requirements and ready to deliver cleaner water throughout the home.
