For whole-house use, jumbo is the right choice.\u003c\/p\u003e\n\n\u003ch3\u003eWhat does WaterMark certification mean?\u003c\/h3\u003e\n\u003cp\u003eWaterMark (WMTS-103, Lic. 032114) means the housing has been independently tested and certified to meet Australian and New Zealand plumbing standards. It's a mandatory certification for plumbing products in NZ and Australia.\u003c\/p\u003e\n\n\u003ch3\u003eWhat does AS\/NZS 4020 mean?\u003c\/h3\u003e\n\u003cp\u003eIt means the housing has been tested for use in contact with drinking water — covering the materials used and their effect on water quality. Not all housings carry this; it's a meaningful differentiator.\u003c\/p\u003e\n\n\u003ch3\u003eDoes it come with a cartridge?\u003c\/h3\u003e\n\u003cp\u003eThe housing is available with or without a cartridge. Select from the dropdown — housing only, or housing with your preferred 10\" jumbo cartridge.\u003c\/p\u003e\n\n\u003ch3\u003eWhy does it have a pressure relief valve?\u003c\/h3\u003e\n\u003cp\u003eThe pressure relief valve releases pressure from the housing before you unscrew the bowl. Without it, a pressurised housing can be very difficult — and occasionally dangerous — to open. Press the valve, hear the hiss, then unscrew.\u003c\/p\u003e\n\n\u003ch3\u003eHow often do I need to change the cartridge?\u003c\/h3\u003e\n\u003cp\u003eIt depends on the cartridge type and your water quality. Most cartridges are replaced every 6–12 months. A drop in flow rate or pressure is usually the first sign it's time to change.\u003c\/p\u003e\n\n\u003ch3\u003eDo I need a plumber to install it?\u003c\/h3\u003e\n\u003cp\u003eThe housing is designed for DIY installation and connects via standard female thread fittings. Many customers install these themselves. If you're unsure about your plumbing setup, a plumber can do it quickly.\u003c\/p\u003e\n\n\u003ch3\u003eWhat warranty applies?\u003c\/h3\u003e\n\u003cp\u003eThe housing carries a 1-year warranty. Cartridges are consumable items and are not covered by warranty, but get in touch if anything arrives damaged or defective.\u003c\/p\u003e\u003cdiv style=\"background:#fff3cd;border:1px solid #ffc107;border-radius:8px;padding:16px;margin:20px 0;\"\u003e\n\u003cp style=\"margin:0 0 8px;font-weight:700;color:#856404;\"\u003e⚠️ Disclaimer – Collective \/ Dropship Product\u003c\/p\u003e\n\u003cp style=\"margin:0;font-size:14px;color:#856404;\"\u003eThis product is supplied \u0026amp; shipped directly by the brand via Shopify Collective.
