The pump circulates the chemical through the heating system under high flow and turbulence, mobilising debris. Once the flush is complete and discharge water runs clear, the Neutralising Crystals are dissolved into the waste water before draining to raise pH to environmentally safe levels. A fresh dose of inhibitor (such as Kamco Benz) should then be added to protect the newly cleaned system.\u003c\/p\u003e\n\n  \u003cdiv class=\"kc-warn\"\u003e\n    ⚠️ \u003cstrong\u003eDisposal requirement:\u003c\/strong\u003e FX2-treated discharge must be neutralised using the included Neutralising Crystals before draining to surface water or foul sewer.

This 4-pack will therefore treat approximately four domestic systems. Larger systems may require additional chemical.\u003c\/div\u003e\n  \u003cdiv class=\"kc-faq-item\"\u003e\n\u003cstrong\u003eCan FX2 be used without a power flushing pump?\u003c\/strong\u003eFX2 is formulated for use with a power flushing pump and relies on the high turbulent flow these machines generate to effectively mobilise and remove debris. It is not recommended for gravity or static chemical cleaning.\u003c\/div\u003e\n  \u003cdiv class=\"kc-faq-item\"\u003e\n\u003cstrong\u003eIs FX2 suitable for systems with a new aluminium boiler?\u003c\/strong\u003eNo. FX2 is not compatible with aluminium heat exchangers or components.

FX2 is a flushing and cleaning agent — once the system is clean and refilled, a long-term corrosion inhibitor (such as Kamco Benz or equivalent) should be added to protect the system going forward.\u003c\/div\u003e\n  \u003cdiv class=\"kc-faq-item\"\u003e\n\u003cstrong\u003eWhy is neutralisation necessary?\u003c\/strong\u003eFX2 is an acid-based formula that lowers the pH of the waste water.
