What happens when my rainwater tank is empty? This is a frequently asked question, but the answer is simple. Every rainwater system always has a mains water backup. Depending on the type of rainwater system, either the tank is 10% filled with mains water or the pump system automatically switches to mains water. This happens automatically and you don’t have to do anything.

When choosing a rainwater tank it is, of course, important to take the changing climate into account. Our advice is to choose a large tank which will provide you with at least one month’s supply. If it is very dry for four weeks, you can continue to use rainwater from your own tank.
