EcoBowser pumping control system

Greywater is sticky stuff. It plays havoc with small floating sensors, especially if they are mounted on a vertical rod.

Also, Earth Leakage Detectors (safety swwitches) can create electrical spikes in the system power supply, and can cause reliability issues with the electronic controllers.

For this reason we design our system with a single pump float switch, modified so the float has a very low activation level.

A lower trickle valve can be fitted so greywater can slowly drain down to a 75mm level. A bottom trickle valve can also be fitted to completely drain the container. Our control systems are approved under the national Watermark standard.

By using trickle valves, the EcoBowser collection container does not require electronic controllers nor water sensors. This enables affordable system pricing without compromising pump quality, the key to system longevity and return on investment.

Detailed description of electronic sensors and 24 hour timers:

Electronic 24 hour control systems generally include 2 water level sensors and a 24 hour based computer chip controller.

The first sensor might be positioned 200mm above the base of the container (height is dependent on the system design).

The second sensor might be positioned 50mm above the base of the container (again dependent on design).

During normal operation, the pump turns on when the upper sensor is activated, and then turns off when the lower sensor drops, making sure the pump has a decent 'burst' of water it can send out.

Generally these sensors require frequent maintenance to ensure greywater is not lost, and the pump not damaged by running dry.
