FAQ
Find answers to common questions about our self-cleaning rainwater filters, installation, maintenance, and how they help you save thousands of liters annually.
1. How does a Rainy filter work?
🡪Rainy filters work on dual working principles depending on the intensity of the rain. During periods of light rainfall, it relies on "cohesive force," and during periods of heavy rainfall the filter automatically switches over to "centrifugal force". These filters require no external energy; they rely solely on gravity.
2. What filter is best for rainwater harvesting?
🡪It is recommended to purchase self-cleaning filters to avoid frequent manul maintenance and to look for high-efficiency filters. Here at Rainy, we have designed a cost-effective, self-cleaning, dual-intensity filter that operates at a high level of efficiency.
3. What is Rooftop rainwater harvesting?
🡪Rooftop rainwater harvesting is the practice of collecting and storing rainwater that falls on rooftops for later use. This involves capturing rainwater from rooftops and directing it into a storage system such as a tank, cistern, or underground reservoir after passing it through a filter apparatus. Rooftop rainwater harvesting systems typically include a gutter system to collect rainwater from the roof and downspouts or pipes to channel the water to a storage tank. The collected water is then treated and filtered as needed for its intended use.
4. How to install RAINY Filters?
🡪Rainy filters are simple to install and are wall mountable units. 360-degree union rotation capability make Rainy filter suitable for any site conditions. It can be easily wall mounted, self-installable with easy to understand instructions make it user friendly or any local plumber with minimal experience is sufficient for installing.
5. How often should I maintain Rainy Filters?
🡪Rainy filters do not require routine maintenance because they are self-cleaning and auto-flushing systems. Nevertheless, we recommend inspecting filters once a year and clean the filter before the rainy season.
