The Waimana 20PL20 catches dirt, debris, rust flakes, and coarse particles from rainwater, tank water, and mains supplies — and when it loads up, you can rinse it clean and put it straight back in.\u003c\/p\u003e\n\n\u003cp\u003eThe 20 inch jumbo format means significantly more filter media than a 10 inch cartridge — a higher flow rate of 110 L\/min, greater particle-holding capacity, and longer service life between cleans.

That means it catches more particles before it loads up, lasts longer between cleans, and maintains better flow under load. When pressure drops or flow slows, rinse it off and reinstall — no need to replace it every time.\u003c\/p\u003e\n\u003cp\u003eAt 20 micron, this cartridge targets coarse sediment. It's typically used as the first stage in a multi-stage system, catching the bulk of the debris before it reaches a finer 1 or 5 micron filter or a UV chamber.\u003c\/p\u003e\n\n\u003ch2\u003eHow to clean and reuse\u003c\/h2\u003e\n\u003col\u003e\n  \u003cli\u003eShut off the water supply and relieve pressure from the housing.\u003c\/li\u003e\n  \u003cli\u003eRemove the cartridge using the housing wrench.\u003c\/li\u003e\n  \u003cli\u003eRinse under a tap or hose off visible sediment — work from the inside out if possible.\u003c\/li\u003e\n  \u003cli\u003eFor stubborn deposits, soak briefly in clean water, then rinse thoroughly.\u003c\/li\u003e\n  \u003cli\u003eSterilise with a dilute bleach solution before reinstalling, then rinse again.\u003c\/li\u003e\n  \u003cli\u003eReinstall and restore water supply.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003eNote: even with regular cleaning, all pleated cartridges have a finite life.

It's the right choice as a first-stage filter in a multi-stage system. If you need finer filtration for silt or fine particles, a 1 or 5 micron cartridge is used downstream.\u003c\/p\u003e\n\n\u003ch3\u003eHow is the 20 inch version different from the 10 inch?\u003c\/h3\u003e\n\u003cp\u003eThe 20 inch jumbo format contains more filter media — this means a higher flow rate (110 L\/min vs 60 L\/min), greater particle-holding capacity, and longer service life between cleans. It's the better choice for larger households and high-flow installations.\u003c\/p\u003e\n\n\u003ch3\u003eHow often do I need to replace it?\u003c\/h3\u003e\n\u003cp\u003eWe recommend replacing every 6–12 months depending on your water quality and usage. Because it's cleanable, you can extend the time between replacements by rinsing it when flow slows — but replace it when flow doesn't recover after a clean or when the pleats look damaged.\u003c\/p\u003e\n\n\u003ch3\u003eCan I really clean and reuse this cartridge?\u003c\/h3\u003e\n\u003cp\u003eYes. Pleated polypropylene cartridges are designed to be rinsed clean and reinstalled. See the cleaning steps above. Replace when it no longer recovers after cleaning.\u003c\/p\u003e\n\n\u003ch3\u003eWill it fit my housing?\u003c\/h3\u003e\n\u003cp\u003eIt fits most 20 inch jumbo housings — these take a cartridge that's 20 inches long and 4.5 inches in diameter. If you're not sure of your housing size, measure the inside diameter before ordering. Get in touch if you're not sure.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I know when to clean or replace it?\u003c\/h3\u003e\n\u003cp\u003eThe clearest sign is a drop in water pressure or flow rate. When you notice the pressure is lower than usual, remove and rinse the cartridge. If pressure doesn't recover after cleaning, replace it.\u003c\/p\u003e\n\n\u003ch3\u003eDo I need special tools to change the cartridge?\u003c\/h3\u003e\n\u003cp\u003eJust the housing wrench that came with your system. Shut off the water first, unscrew the housing, swap the cartridge, and reinstall. A quick rinse of the housing while it's open is good practice.\u003c\/p\u003e\n\n\u003ch3\u003eIs it suitable for drinking water?\u003c\/h3\u003e\n\u003cp\u003eIt's made from food-grade polypropylene and is suitable for use in drinking water systems. The spec sheet cautions that it should not be used with microbiologically unsafe water without adequate disinfection — so if your water source carries biological risk, pair it with a UV system downstream.\u003c\/p\u003e\n\n\u003ch3\u003eWhat warranty applies?\u003c\/h3\u003e\n\u003cp\u003eFilter cartridges are consumables and don't carry a standard product warranty. If you receive a cartridge that is visibly damaged or defective, get in touch and we'll sort it out.\u003c\/p\u003e","brand":"Waimana Water","offers":[{"title":"Default Title","offer_id":45492351598636,"sku":"20PL20","price":55.2,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0623\/5966\/6732\/files\/5_Waimana20PolyPleatedFilter.jpg?v=1777327319","url":"https:\/\/www.filtrationstation.co.nz\/products\/waimana-20-inch-jumbo-pleated-sediment-filter","provider":"Filtration Station NZ","version":"1.0","type":"link"}
