Why this product

Solve the Real Problems

Shutting down the water line for every cartridge change is disruptive. Big White with Bypass lets you switch between filtered and bypass modes at the housing—keeping service simple and downtime low.

Easy Cartridge Change‑Outs

Built‑in bypass valve in the cap means you don’t have to shut off the main water supply during service—just turn the control knob a half turn to bypass.

High‑Flow, Large Capacity

Extra‑large housings provide greater cartridge capacity and can reduce the number of vessels required for high‑flow or heavy‑sediment applications.

Durable Construction

Polypropylene sump and HFPP cap with EPDM O‑ring are designed for dependable service, with a pressure relief button for easier depressurisation.
