Whole house filtration systems
Quite often, a rain water tank intended for drinking water will use a whole house filter system. These systems tend to be more robust than those used for irrigation, as they need to remove a wider range of contaminants.
A whole house rainwater filtration system typically consists of three main components: a pre-filter, a sediment filter, and a carbon filter. The pre-filter is installed before the rainwater enters the tank, and it’s designed to remove large particles such as leaves and twigs.
The sediment filter is installed after the pre-filter, and it’s designed to remove smaller particles such as dirt and sand. Finally, the carbon filter is installed after the sediment filter, and it’s designed to remove dissolved contaminants such as chlorine and bacteria.
We also recommend a UV system (ultraviolet systems) for rainwater tanks, as UV light can kill bacteria and other microorganisms that may be present in the water.
If you’re using your rainwater for drinking water, it’s important to make sure that your filtration system is designed to remove all of the contaminants that could potentially be present in your water. A professional like the team at Water Filter can help you select the right whole house system for your specific needs.
Rainwater tank filters
After installing a whole house filter system, the next most important thing is the maintenance schedule. Depending on the type of system you have, the frequency of maintenance will vary.
As a general rule, we recommend changing the pre-filter cartridge every 3 to 6 months, the sediment filter every 6 to 12 months, and the carbon filter every 1 to 2 years. Additionally, the UV lamp should be replaced annually. It’s important to understand that failing to replace filter cartridges and UV lights on a regular basis can result in decreased water quality and potentially health risks.
If you’re not sure how often your rainwater tank filter needs to be replaced, consult with a professional or the manufacturer of your filtration system. They can help you develop a maintenance schedule that’s appropriate for your specific situation.
If you have a well-maintained rainwater tank filter system, you can be confident that your water is safe to drink. If you have any questions about filtration systems or maintenance schedules, feel free to contact us and we’ll be happy to help.
