Vent Cowl FAQs
When would I use a weatherproof vs a standard vent cowl?
Both standard and weatherproof vent cowls allow fresh air to circulate within your rainwater tank. Weatherproof vent cowls incorporate a cap that shields the stainless steel screen from light (UV) and the weather. They can be used to provide a light (UV) and weather-proof vent on the top surface of your rainwater tank.
Do I need to use a vent cowl if I have a Maelstrom filter installed on my tank?
Vent cowls are optional for rainwater tanks with and without Maelstrom filters. However, the benefit of a vent cowl is that it will ensure the unrestricted flow of fresh air within your tank.
