RoofWhirlys4Africa Toilet / Sewer Vent to fit 110mm Pipe - White - Made in South Africa

RoofWhirlys4Africa toilet/sewer vents for healthy natural ventilation of toilets and sewerage systems. Designed and manufactured in South Africa, this innovative plastic product (with galvanised moving components) offers 24/7 ventilation with zero operating costs. The RoofWhirlys4Africa sewer/toilet vents are designed and manufactured from completely non-corrosive materials to withstand the impact of noxious air streams from sewers, toilets, pits and drains. They are exceptionally durable and can withstand extreme climate, wind or rain. When a septic tank's ventilation system is insufficient it develops lingering foul odours. Installing a RoofWhirlys4Africa wind driven turbine ventilator ensures almost no smell. This product is for a toilet/sewer and NOT for a chimney.
