Hand-tighten both the flush valve nut and the inlet backnut to the ceramic and add no more than a quarter turn — over-tightening damages either mechanism and is not covered by Siamp’s warranty. Use no sealing paste or compound. Tap connector not supplied. Maximum water level is 20 mm below the overflow. Use no limescale or chlorine cleaners in the cistern.\u003c\/p\u003e\n\u003c\/div\u003e\u003cp\u003eSpecification sheets: \u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0858\/5268\/4624\/files\/file-optimas.pdf\"\u003eOptima S flush valve (PDF)\u003c\/a\u003e · \u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0858\/5268\/4624\/files\/file-compactod99tbp.pdf\"\u003eCompact OD 99T BP filling valve (PDF)\u003c\/a\u003e · \u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0858\/5268\/4624\/files\/50_6736_00_LD.pdf\"\u003eInstallation manual (PDF)\u003c\/a\u003e · \u003ca href=\"\/it\/collections\/toilet-cistern-parts\"\u003eSee related WC cistern parts\u003c\/a\u003e.\u003c\/p\u003e","brand":"Siamp","offers":[{"title":"Default Title","offer_id":53468754280784,"sku":"37941110","price":39.29,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0858\/5268\/4624\/files\/siamp-37941110-1024-crisp_622ac0b9-288d-4b4c-923b-d1b9720aa6b5.jpg?v=1787764869","url":"https:\/\/getplumb.co.uk\/it\/products\/siamp-eco-deluxe-optima-s-and-99t-bp-delayed-action-wc-component-pack","provider":"Getplumb","version":"1.0","type":"link"}
