A tank for collecting rainwater has a variety of uses, but to make the best of your tank, you will need to get the right extras and add-ons. Here are some of the options that will help to customise your rainwater tank for your needs.

Water level gauge

This is a highly useful addition to a water tank that can usually be added to any kind of water tank. There are different types of level indicators, but they typically use a float in the tank that attaches to a pulley system, which then moves a marker on an indicating gauge on the outside of the tank. This means you can see at a glance how much water is in the tank, so you will know if you have enough for your current purposes.

Rainwater-to-mains switch

This is a useful device to have if your tank is prone to running dry. The switch ensures that if you use up all the rainwater you have collected, it will automatically switch to the mains supply instead so that your water use is not interrupted. This is particularly important if you are using your rainwater for domestic purposes. The switch should also reduce your mains water usage as it will use rainwater whenever possible.

Strainers

A variety of strainers are available, which all have the same purpose — to keep your rainwater pure and free from debris. Strainers can be fitted to the tank's opening to prevent leaves, insects and airborne dust from entering the water supply. Gutter guards will protect the pipes that flow into your tank, preventing any build-up of leaves. A "first flush" diverter can be installed which will prevent the first run-off of rainwater, which is prone to containing debris, from entering your tank. Lastly, you can fit a cover to your tank which will keep the sunlight off and prevent the formation of algae.

Fire fighting coupling

Finally, whatever the purpose of your rainwater tank, it is smart to add a fire-fighting coupling to it so that a hose can be attached. Your water tank can then be used to fight any fires that arise and will help to protect lives and property.

With a little thought, your tank can be customised so that it serves your particular needs. Just discuss your requirements with your supplier and make sure you get the right rainwater tank for your specific needs.
