The recent droughts in Australia have forced many homeowners to rethink their tank water filtration systems. Rainwater filters are now becoming more popular than ever because they can help conserve water and give a purified form of the fluid without using up too much electricity. This article will provide an overview of this type of system and serves as an introductory primer for those who have never used one before.

Rainwater filters: How they work

Most rainwater filters work in a similar fashion — by using membranes to separate out any contaminants into two distinct streams; the clear, filtered stream is then sent back through the original membrane which traps any remaining pollutants before being stored in a water tank. The contaminated wastewater is then flushed away into the local drainage system.

Benefits of rainwater filters

Rainwater filters offer a number of advantages over traditional sewage systems. One key benefit is that rainwater tanks do not require any chemicals for primary treatment and are 100% odour-free. The most popular kinds of rainwater filters are activated carbon filters, but these tend to be more expensive than other types because they usually require a power source and additional equipment outside the tank.

Secondly, the high-quality rainwater filters found on the market can last for years without major repairs and will reduce bacteria build-up over time.

The role of a plumber when installing and maintaining a system

Many homeowners who use rainwater filters find that their local plumber can be very helpful in terms of installation and maintenance. The plumber will be able to install the water tank and the pipes which will carry the water into and out of the filtration system.

If you are using a rainwater tank, it is important to note that the filter should be cleaned at least every two weeks depending on how much water you are using. Unblock drains after heavy rainfall to avoid overflow and note that your filter will need more frequent cleaning if you opt to use the water for cleaning or watering plants. It may be possible to schedule regular maintenance with your plumber if you do not feel like doing this work yourself.
