Tank water board switch

David87

I wish to drink rain water and not the water that arrives by water main.

I wish to know the mechanism by which I can simply and easily change over source.

Presumably a one way valve should be installed.

The rain water tank will supply the whole house whilst the main water can be used for the garden.

Hello @David87

There are some things to consider if you are using your rainwater tank as your main source of water for your house. One of the most important things to consider is the water safe to drink? Proper tank maintenance and decontamination of the water in the tank is important. If you're worried about the water from your mainline you could install a Stefani Whole House Filter System in combination with a Stefani Filter Undercounter Triple Stage. However, before you purchase any parts, I suggest checking with your local council on the rules and regulations regarding using your water tank as your main source of water. 

You can install a manual system where you shut off the mainline and redirect the water source to your water tank. Some systems have an auto-top up from the mainline when there is not enough rain and your water tank is getting dangerously low. However, if you're not keen on this type of auto top-up, your only option is to filter the water. 

Let me tag our experienced members @TedBear, @r23on, and @JoeAzza for their recommendations.

If you need further assistance, please let us know.
