Toilet flush

Use rainwater for your toilet

A domestic hot water system for the home and garden reduces your drinking water consumption immensely. You can easily save 40 liters per day, especially when flushing the toilet. Drinking water is far too expensive and too valuable to flush down the toilet.

Using rainwater to flush toilets offers a number of advantages. On the one hand, drinking water consumption is naturally reduced, which of course also lowers the associated costs. In addition, the longevity of the fittings is increased as they are less maintenance-intensive due to the use of soft and low-limescale rainwater.


The implementation of a toilet flush with rainwater requires a few installation steps. First of all, a cistern must be installed as a water storage tank, if not already present. As drinking water and service water must always remain separate, a separate water pipe is only required for the service water. A separate pipe from the cistern to the cistern is therefore required for flushing the toilet. To keep costs as low as possible, we recommend using pipes from a roll. A domestic water system pump is also required to ensure a constant pressure in the domestic water pipe.


The use of rainwater for toilet flushing is particularly recommended if you are currently in the planning phase of a new build or if you are about to renovate your house pipes.
