When you need to link different shaped gutters, square to round gutter adaptors are vital. This might happen when building an extension, during a property upgrade project, or perhaps when doing repairs or replacements. Sometimes adaptors are also needed when old and new fittings need to be connected.
You’ll typically be installing a square to round guttering adaptor at the junction between the gutter and the downpipe, often near the eaves. They’re available in several sizes and materials to suit different systems and building types. Most are push-fit or solvent-weld depending on the pipework, and compatibility is key when working with older or region-specific fittings. Where drainage layouts change direction or section, adaptors help maintain flow without major reconstruction.
