How many consumers can be connected to the RAINMASTER Eco?

Can I replace an old device with the RAINMASTER Eco?

Many rainwater systems are getting old and customers want to exchange the old pumps or rainwater units with modern devices. The RM-Eco is perfectly suitable for this since it comes already supplied with flexible connections. An existing suction line (even with a 1" connection size) and the floating switch cable belonging to old device can be used if these are 100% water-tight and not worn out.

Do I need the fill level indicator?

With the fill level indicator, you can be comfortable with the knowledge your cistern water level is always in view. By being able to monitor the water level in your cistern, you can make decisions on whether the water level is sufficient for additional uses such as watering the garden, filling a pond or if an extra car wash is called for.

Can I also use the RAINMASTER Eco for my well, pond, non-potable, or greywater?

The RAINMASTER Eco, as it’s name suggests, was developed for rainwater harvesting, but can be also be used for numerous other water applications. It may also supply well water (up to a 3m intake level), treated wastewater, water from streams and ponds or water from a greywater recycling system, like the INTEWA AQUALOOP. Should water from the natural/treated source run short, the unit automatically switches over to a DVGW approved mains water supply, so household water needs are always covered.
