Design Specifications

The system has two models 12/24 or 48/120 volts. The output power of the device is up to 200 W. It is small and weighs only 3.6 kg. The number of nozzles can range from 1 to 4.  Brass nozzles are supplied with the device from 3 mm up to 7 mm in size. For higher head applications smaller nozzles can be used and for lower head applications larger size nozzles can be used. See performance charts below.

Technical Support

The manufacturers in Canada may provide technical support. Local electricians or plumbers may be of assistance but it is possible that they are not familiar with this specific technology. Additionally, the manufacturer provides a user manual, which offers advice on measuring flow rate, determining head, and guiding the installation of the system, although the directions are fairly complex and require some technical expertise. Not all parts necessary for a complete system are included in the kit

Replacement Components

Manufacturer Specified Performance Parameters


Vetted Performance Status



Varying water flow rates can cause an increase in voltage beyond battery rated capacity (potentially lethal), improper installation can lead to electrical fires.

Complementary Technical Systems

Additional components can be purchased by sending a direct inquiry regarding additions to the water buddy system.
