Also known as the K5567.\u003c\/p\u003e\n\n\u003cp\u003eThe KDF works through electrolytic and oxidation reactions to reduce a wide range of contaminants and provides a bacteriostatic effect hostile to algae, fungi, and bacteria. The GAC adsorbs and traps contaminants that affect taste and odour. Together they deliver superior filtration to 30,000 litres.\u003c\/p\u003e\n\n\u003cp\u003eCyst safe.

It also provides a bacteriostatic effect, creating an environment hostile to algae, fungi, and bacteria — which extends the useful life of the GAC and keeps the cartridge cleaner between replacements.\u003c\/p\u003e\n\n\u003ch3\u003eWhat does GAC do?\u003c\/h3\u003e\n\u003cp\u003eGAC (granular activated carbon) adsorbs and traps contaminants that affect taste and odour, including chlorine and related by-products.\u003c\/p\u003e\n\n\u003ch3\u003eWhich fitting type should I choose?\u003c\/h3\u003e\n\u003cp\u003eIf your existing system uses 1\/4\" push-fit tubing, choose JJ. If your system connects via male threaded fittings, choose BB. If you're unsure, get in touch and we'll help you identify the right type before you order.\u003c\/p\u003e\n\n\u003ch3\u003eHow often do I need to replace it?\u003c\/h3\u003e\n\u003cp\u003eAt least annually, or when 30,000 litres is reached, or when flow noticeably slows — whichever comes first. In commercial or office settings where usage is higher, replacement may be needed more frequently.\u003c\/p\u003e\n\n\u003ch3\u003eDo I need a PRV?\u003c\/h3\u003e\n\u003cp\u003eYes — a pressure reduction valve must be installed prior to the filter. Flow must not exceed 5 LPM.\u003c\/p\u003e\n\n\u003ch3\u003eCan I use it with rainwater, tank, or bore water?\u003c\/h3\u003e\n\u003cp\u003eNo — the OKDF30\/1 is designed for mains (town) water supply only. It is not suitable for rainwater, tank, bore, or surface water.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I install the JJ push-fit version?\u003c\/h3\u003e\n\u003cp\u003eBefore installing, carefully remove the small protective tubing plugs fitted at the factory. Hold the collet fitting against the filter body with a fingernail and gently pull the tubing out — do not force it, as this can damage the fitting. Cut your tubing square across (not diagonal) and push firmly into the fitting until it bottoms out. Check flow direction — water must flow through KDF first, then GAC. Flush for 5 minutes before use.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I install the BB threaded version?\u003c\/h3\u003e\n\u003cp\u003eWrap the male threads on your fittings with thread sealing tape, screw on firmly, and check flow direction — water must flow through KDF first, then GAC.
