Introducing Siphonic Roof Drainage

摘要

Siphonic roof drainage differs from conventional gravity drainage in what is called 'full-bore flow.' Unlike conventional drainage, a fully engineered siphonic roof drain system prevents air from entering, allowing the pipes to be completely full of water. Assemblies feature an air baffle to prevent air from entering the piping system at full flow and protects against debris. First developed in Finland in 1968, siphonic roof drainage systems account for one-fifth of commercial projects in Europe.
