About this item
  • Simple Application: Designed for hassle-free use, this leak sealer disperses rapidly through your heating system without the need for dismantling or draining. Just dose directly into the system using a compatible access point and allow the water circulation to distribute the formula evenly.
  • Seals Minor Leaks: Created specifically to seal minor and hard-to-access leaks, including pinholes and slow weeps. This solution is perfect for preventing further damage without the need for expensive and disruptive repairs or system shutdowns.
  • Material Safe: This versatile formula is safe for use with all commonly used metals in heating systems, including aluminium, copper, steel, and their alloys. It integrates smoothly with modern and traditional components without causing corrosion or adverse reactions
  • No Blockage Risk: Engineered to maintain free-flowing operation, this product will not clog or obstruct pipes, pumps, or valves. It circulates cleanly through your system, sealing where needed without affecting the efficiency or longevity of your heating unit.
  • Covers Large Systems: A single 500ml bottle is sufficient for a standard household system with up to 10 radiators or 100 litres of water. Larger systems can be treated with proportionally more product to ensure thorough and lasting protection against leaks.
Product description

This 500ml central heating leak sealer provides a practical and efficient solution to stop small internal leaks and weeping joints within your homeโ€™s heating system. The formula begins to work within 24 hours once evenly circulated in warm or hot water. Its compatibility with all system materials, including aluminium, ensures it suits a wide range of setups. Itโ€™s ideal for both open and sealed systems and can be dosed via various access points, such as F&E cisterns, filling loops, or bypass feeders. For optimal results, itโ€™s recommended to circulate the system normally for at least 15 minutes after application. This product supports the longevity of your system by preventing pressure drops and water damage while maintaining smooth internal flow. Whether you're dealing with ageing components or minor wear, this solution provides a cost-effective, non-invasive fix that keeps your home heating efficient and reliable.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days โ€” so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
