The original REEFER 170 uses a different valved downpipe. Check your cabinet or purchase documentation for the \"G2\" designation before ordering.\u003c\/p\u003e\n\u003ch4\u003eWhat does the valve actually do?\u003c\/h4\u003e\n\u003cp\u003eIt lets you throttle flow through the downpipe, which is how a Herbie-style overflow is tuned for near-silent operation. Closing it fully also lets you isolate the downpipe for sump maintenance without draining the display.\u003c\/p\u003e\n\u003ch4\u003eMy overflow has gone loud — is this the fix?\u003c\/h4\u003e\n\u003cp\u003eIt's one of the most common causes. If the valve setting hasn't changed but the noise has, a worn seal or a partial blockage inside the downpipe is often the reason, and a replacement resolves both.\u003c\/p\u003e","brand":"RedSea","offers":[{"title":"Default Title","offer_id":54774155804963,"sku":"RED516i","price":301.95,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/red-sea-reefer-170-g2-aquari-43876676043043.webp?v=1790239001","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/red-sea-reefer-170-g2-aquarium-sump-valved-downpipe","provider":"Nicks AOT","version":"1.0","type":"link"}
