If your tank is a Reefer Nano, 170, 250, 350, 425, 450 or 525, this is the wrong downpipe; those models use a different plumbing diameter. If you're not certain which range your tank belongs to, send us the model plate photo or your order number and we'll confirm before you buy.\u003c\/p\u003e\n\u003ch3\u003eWhy this fails\u003c\/h3\u003e\n\u003cp\u003eOverflow downpipes crack or develop hairline leaks with age and UV exposure, or after being over-tightened during a plumbing rebuild. A cracked downpipe usually shows up as water tracking down the outside of the sump cabinet wall rather than a sudden leak — worth checking during routine maintenance on an older system.\u003c\/p\u003e\n\u003ch3\u003eFitting\u003c\/h3\u003e\n\u003cp\u003eHand-tight into the overflow fitting, no solvent welding required on the standard REEFER push-fit plumbing. Renew the O-ring or seal on the connection when you replace the downpipe — the seal is usually the actual point of failure, and a new downpipe on an old, hardened seal can still leak.\u003c\/p\u003e\n\u003ch3\u003eCare and maintenance\u003c\/h3\u003e\n\u003cp\u003eClean downpipes during major maintenance — biofilm buildup inside overflow plumbing is the usual cause of a gurgling overflow that develops gradually over time, and is often mistaken for a plumbing fault when a clean resolves it.\u003c\/p\u003e\n\u003ch3\u003eWarranty and delivery\u003c\/h3\u003e\n\u003cp\u003eCovered by Red Sea's manufacturer warranty on manufacturing defects, additional to your rights under Australian Consumer Law.

A standard Reefer 350 uses a different, smaller downpipe.\u003c\/p\u003e\n\u003ch4\u003eDo I need to replace the seal as well?\u003c\/h4\u003e\n\u003cp\u003eIt's good practice to renew the O-ring or seal at the same time — a worn seal is the more common cause of a leak than the downpipe itself, and reusing an old, hardened one can leave the new part leaking too.\u003c\/p\u003e\n\u003ch4\u003eIs this sold as a single part or a set?\u003c\/h4\u003e\n\u003cp\u003eSingle downpipe.\u003c\/p\u003e","brand":"RedSea","offers":[{"title":"Default Title","offer_id":54774160654627,"sku":"RED816c","price":202.95,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/red-sea-reefer-overflow-down-46119457128739.webp?v=1790239293","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/red-sea-reefer-overflow-downpipe-rf-s-850-s-1000-g2-900-s-850-s-1000","provider":"Nicks AOT","version":"1.0","type":"link"}
