Types of Rainwater Tank Filter Systems

Thinking about filtration options for your water tank? But how do you work out which is the right choice for you?
Looking at all the options for your water tank filtration available can be quite daunting.

Inline Filtration Vs. Under Sink Filtration

There’s also the filter’s location to consider. Have you thought about under sink or inline filtration?

Inline Filtration (Whole House Systems)

Inline filtration is generally whole building or whole of house filtration. Sometimes these filters will be mounted on the wall of a building or fence with the connection branching off afterwards to the whole building. 

These systems are typically installed:

• Along your main water line
• Near your water meter
• Mounted on an external wall or fence

They are ideal if you want:

• Clean water from every tap
• Protection for appliances and plumbing
• A full-home solution for rainwater use

Inline systems are a popular choice for households relying heavily on rainwater tanks, especially in larger homes or rural properties.

Under Sink Filtration (Point-of-Use Systems)

Under sink is usually easier and therefore cheaper to install as this type of filter system only filters one tap. However, the options for under sink filtration are wider and can cater for more filtration purposes than whole of house. This may include reverse osmosis, chlorine and sediment, and even for catering such as hot, sparkling and chilled water filtration systems.

They are generally:

• Easier to install
• More cost-effective upfront
• Focused on drinking and cooking water

One of the biggest advantages is flexibility. These systems can include:

• Sediment and carbon filtration
• Chlorine reduction
• Reverse osmosis systems
• Options for chilled, sparkling, or instant hot water

Most setups work best with a mixer tap, but if your kitchen doesn’t have one, there are still solutions available. Bench-mounted or wall-mounted taps can be installed, and systems can be adjusted to suit your layout.

Can You Use These Systems With Rainwater Tanks?

Yes. Both inline and under sink filtration systems can be installed with rainwater tanks as well as mains water systems.

This means you can:

• Filter all water entering your home
• Or focus only on specific taps like your kitchen

The right setup depends on how you use your rainwater and what level of filtration you’re after.

Finding the Right System

The best filtration system comes down to a few key factors:

• How much water you use
• Whether you want whole-house or single-tap filtration
• Your budget
• The quality of your existing water
