{"product_id":"kockney-koi-4-tommy-bottom-drain","title":"Kockney Koi 4\" Tommy Bottom Drain","description":"\u003cp\u003eA mushroom-domed bottom drain for koi ponds and large garden ponds, built to draw sludge and fish waste off the pond floor while keeping fish well away from the outlet itself. It helps keep the base of fibreglass, concrete and rubber-lined ponds cleaner with less manual maintenance.\u003c\/p\u003e\u003cp\u003eOverview The Kockney Koi 4\" Tommy is a mushroom-domed bottom drain designed to pull waste from the floor of koi ponds and large garden ponds, keeping fish safely away from the outlet while it helps reduce sludge build-up on the pond base. It suits koi keepers and pond builders working with fibreglass, concrete or rubber-lined pond construction.\u003c\/p\u003e\u003cp\u003eSited in the deepest part of the pond, the domed cover lets sludge, debris and fish waste draw through to the filtration system while physically blocking fish from the opening. This cuts down how often the pond floor needs manual cleaning and supports steadier water circulation.\u003c\/p\u003e\u003cp\u003eThe outlet fitted here is built for higher flow rates, making it better suited to larger pond installations than small, low-turnover ponds.\u003c\/p\u003e\u003cp\u003eYou receive one bottom drain unit, ready to fit into the pond base.\u003c\/p\u003e\u003cp\u003eKey benefits This drain is manufactured in the UK, where Kockney Koi has been producing pond equipment for over 35 years. The mushroom dome approach is a long-established choice among professional pond builders and koi keepers for combining safe waste removal with fish protection.\u003c\/p\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutlet Size\u003c\/td\u003e\n\u003ctd\u003e4 inch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDrain Style\u003c\/td\u003e\n\u003ctd\u003eTommy \/ mushroom dome\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePond Compatibility\u003c\/td\u003e\n\u003ctd\u003eFibreglass, concrete and rubber-lined ponds\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"AquaticsHub","offers":[{"title":"Default","offer_id":57620905034101,"sku":null,"price":13.19,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0922\/0610\/4949\/files\/4in-BD_1-scaled.jpg?v=1790892685","url":"https:\/\/aquaticshub.co.uk\/products\/kockney-koi-4-tommy-bottom-drain","provider":"AquaticsHub","version":"1.0","type":"link"}
