What Are Leak Sealers Used For?

Leak seal sprays and liquids can be used to repair cracks in pipes or joints throughout your central heating system. They are fast-acting, with most products becoming effective between 1-24 hours after use. Since the product is applied to the system’s water, leak sealers are a quick fix for inaccessible or internal leaks. Leak sealants offer long-lasting results, protecting your pipes from further leaks and maintaining consistent pressure throughout your central heating system.
