Flexipipes are pieces of piping that are made of a flexible material and with a flexible design. What this does is give piping a small amount of margin for error, allowing for the final piece to be implemented without needing to redo the whole thing if the structure is off by a few milimetres.
At ERoofing, our flexipipes are primarily being made to work alongside vent adaptors so they can mount soil pipes. Soil pipes remove the noxious and unpleasant air from toilet pipes and equalise the pressure. Flexipipes allow this to happen while using inconspicuous roof vents to do so.
