Residential Rainwater Harvesting Rain Harvesting Vent Cowls

Vent cowls include an insect proof stainless steel screen of 0.955mm aperture and can be fitted to the top of rainwater tanks to help vent them properly . They are an ideal method for providing air circulation through tanks where rainwater is piped directly into the top or side of the tank, rather than passing through a tank screen.

The vent cowls from Rain Harvesting are also designed to fit to the top of toilet vent pipes and REDUCE THE POSSIBILITY OF PAN SYPHONING where two toilets are connected to the one line. 

They fit 50 & 100mm PVC & Copper (with the use of a standard 3mm nitrile “O” ring).
