Step 1

Whole House Product Selector

What type of supply do you have?

The first thing to establish is what sort of water supply you have - essentially whether it's treated portable water from one of the water companies, or taken from a well or river on your land. If it's the latter, you may have to add a UV filter to treat your incoming water for micro-organisms, such as those known as protozoa.

As your water supply is private, not from a water company, we recommend that you contact us to discuss your requirements.

Step 2

Do you know your flow rate?

To specify the right size of system for your needs, we need to have a rough idea of your peak water flow rate. You may find this on your water bill, or simply take your average day's water usage and divide it by two (corresponding with the two peaks of usage in early morning and later in the evening), and that figure is your appoximate flow rate.

Enter your flow rate:

Recommended housing size:

Our systems are available in two sizes depending on your flow rate. If you don't know your flow rate, don't worry - our calculator will assume you need the larger size for now.

Step 3

Select number of housings

You can choose whether you want a 2 or 3 housing system. The amount of space you have available and if you want to include a dedicated sediment filter and/or remove various different contaminants may have an impact on your decision.

Step 4

Do your require a dedicated sediment filter?

A dedicated sediment filter’s purpose is to be the first filter to engage with your water and protect the other filters from being impacted by sediment. We always recommend including one, but the choice is yours.
