It connects directly to your existing pond pump, dramatically oxygenates the water, and transforms a flat pond into a stunning living water feature. Easy to install and compatible with most pond pumps.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch2\u003eTransform Your Garden Pond with a Waterfall Spillway\u003c\/h2\u003e\n\u003cp\u003eA waterfall spillway — sometimes called a weir or cascade box — is one of the most impactful upgrades you can make to a garden pond. Rather than a narrow trickle, it creates a wide, even curtain of water that cascades smoothly into your pond, producing a beautiful visual effect and a relaxing sound that enhances any outdoor space.\u003c\/p\u003e\n\u003cp\u003eBeyond aesthetics, the wide waterfall dramatically increases oxygen transfer at the water surface — critical for the health of koi, goldfish, and beneficial bacteria in your filter. Good oxygenation reduces the risk of fish stress and disease, particularly during warm summer nights when dissolved oxygen levels naturally drop.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e✅ Creates a wide, even waterfall curtain — not a narrow trickle\u003c\/li\u003e\n  \u003cli\u003e✅ Dramatically increases pond oxygenation\u003c\/li\u003e\n  \u003cli\u003e✅ Connects to any standard pond pump via hose barb inlet\u003c\/li\u003e\n  \u003cli\u003e✅ UV-stable polypropylene construction — won't crack or fade\u003c\/li\u003e\n  \u003cli\u003e✅ Adjustable levelling feet for precise waterfall angle\u003c\/li\u003e\n  \u003cli\u003e✅ Suitable for streams, raised ponds, and natural-look waterfalls\u003c\/li\u003e\n  \u003cli\u003e✅ Easy installation — no specialist tools required\u003c\/li\u003e\n  \u003cli\u003e✅ Compatible with most filter outlets and pond pumps\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable border=\"1\" cellpadding=\"8\" cellspacing=\"0\"\u003e\n  \u003ctr\u003e\n\u003cth\u003eFeature\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eWaterfall Width\u003c\/td\u003e\n\u003ctd\u003eApprox. 45 cm wide curtain\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eInlet Connection\u003c\/td\u003e\n\u003ctd\u003e38mm \/ 50mm hose barb (adaptors included)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eRecommended Pump Flow\u003c\/td\u003e\n\u003ctd\u003e3,000 – 12,000 L\/h\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eUV-stable polypropylene\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eColour\u003c\/td\u003e\n\u003ctd\u003eNatural stone grey\/brown\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003eApprox. 2.8 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eSuitable For\u003c\/td\u003e\n\u003ctd\u003eGarden ponds, koi ponds, water features, streams\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eDelivery\u003c\/td\u003e\n\u003ctd\u003eFree UK delivery\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eInstallation Guide\u003c\/h2\u003e\n\u003cp\u003ePosition the spillway at the desired height above the pond surface (typically 10–30 cm for the best visual effect). Secure it in place using pond liner, rockery, or a custom timber frame. Connect your pump outlet hose to the inlet barb, ensure the unit is level using the adjustable feet, and switch on the pump. The wide lip creates an even curtain of water across its full width immediately.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdl\u003e\n  \u003cdt\u003e\u003cstrong\u003eWhat pump flow rate do I need?\u003c\/strong\u003e\u003c\/dt\u003e\n  \u003cdd\u003eFor a full, impressive waterfall curtain, we recommend a minimum pump flow rate of 4,000 L\/h. Higher flow rates (up to 12,000 L\/h) produce a more dramatic, voluminous waterfall effect.\u003c\/dd\u003e\n  \u003cdt\u003e\u003cstrong\u003eWill it work with my existing pond pump?\u003c\/strong\u003e\u003c\/dt\u003e\n  \u003cdd\u003eYes, provided your pump has a 38mm or 50mm hose outlet (the two most common sizes). Hose adaptors are included for both sizes.\u003c\/dd\u003e\n  \u003cdt\u003e\u003cstrong\u003eDoes it help with filtration?\u003c\/strong\u003e\u003c\/dt\u003e\n  \u003cdd\u003eThe spillway itself is not a filter, but many pond keepers connect their external filter's outlet directly to the spillway inlet — meaning filtered water re-enters the pond via the waterfall, which is highly effective.\u003c\/dd\u003e\n  \u003cdt\u003e\u003cstrong\u003eIs it suitable for a koi pond?\u003c\/strong\u003e\u003c\/dt\u003e\n  \u003cdd\u003eAbsolutely. Koi require highly oxygenated water, and the surface agitation created by the waterfall is one of the best natural ways to achieve this, reducing reliance on air pumps.\u003c\/dd\u003e\n  \u003cdt\u003e\u003cstrong\u003eWill it freeze in winter?\u003c\/strong\u003e\u003c\/dt\u003e\n  \u003cdd\u003eWe recommend switching off the waterfall during frost and freezing temperatures to prevent ice damage to the pump and pipework. Use a pond heater or de-icer instead to maintain an ice-free area in the surface.\u003c\/dd\u003e\n\u003c\/dl\u003e\n\u003cp\u003e🚚 \u003cstrong\u003eFree UK Delivery\u003c\/strong\u003e | 🐟 \u003cstrong\u003eFish Safe\u003c\/strong\u003e | ✅ \u003cstrong\u003eUK Pond Expert Approved\u003c\/strong\u003e\u003c\/p\u003e","brand":"PondLiners Co","offers":[{"title":"Default Title","offer_id":57667060138332,"sku":"PLF-WS001-S","price":684.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0889\/2035\/9260\/files\/9e7bbfc02ea66cbeb5143efb1bf029da.jpg?v=1779043764","url":"https:\/\/www.pondlinersco.co.uk\/products\/pond-waterfall-spillway-uk-creates-natural-waterfall-effect-oxygenates-water-easy-install","provider":"PondLinersco.co.uk","version":"1.0","type":"link"}
