Standard vent height
The standard kit provides up to approximately 4 metres of vertical vent pipe and is generally suited to a single-storey building with a relatively low-profile A-frame or mono-pitch roof.
Where the building or roof is higher, additional vent-pipe extensions may be required so the completed vent can terminate at the required height above the roof.
Vent height: WCTNZ® installation guidance is to allow sufficient vent length for the termination to sit at least 0.6m above the roof apex. Final vent position and termination should be confirmed for the actual building and installation.
How much additional pipe should I allow?

Planning guide: the quantities above are intended to help with ordering. Building dimensions, roof pitch, vent routing and the position of the composting toilet system can change the actual pipe length required.
Stepping around the roof eaves
Where you would prefer to route the vent around the eaves rather than penetrate the roof, add the appropriate Vent Eaves Step Kit to the installation.
Before ordering: check the proposed vent route, building height and roof profile. If you are unsure how much pipe or which vent accessories are required, contact WCTNZ® with your toilet model and basic building dimensions.
