Frequently Asked Questions

What can I use rainwater for in my home?

Rainwater can be used for toilet flushing, laundry, and garden watering. These are the three largest water consumers in a household, besides baths and showers, and they do not require drinking water quality. Together, this can replace up to half of your water consumption.

Is it safe to wash clothes in rainwater?

Yes. Rainwater is soft water with almost no lime, which is actually an advantage for your washing machine and your clothes.

You use less detergent, and the machine is less burdened by limescale deposits. The system filters the water before it reaches the washing machine.

What happens when it hasn't rained for a long time?

Vi vil arbejde hurtigt på at sende din ordre afsted så hurtigt som muligt. Når din ordre er afsendt, modtager du en e-mail med yderligere information. Leveringstider varierer afhængigt af din placering.

Does it require a lot of maintenance?

No. You check the filter a couple of times a year, and the tank is inspected once a year. It takes only a few minutes and can be compared to the maintenance you already perform on your home.

What is a VA approval — and why is it it important?

A VA approval is an official Danish system approval issued by ETA-Danmark.

It documents that the entire system (filters, tank, pump, and control) has been tested and approved as a complete solution.

MRAIN is currently the only rainwater harvesting system in Denmark with a valid VA approval.

This gives you assurance that the system complies with the building regulations and is continuously quality-controlled by the Danish Technological Institute.
