Rainwater Pump
Nowadays besides drinkable water for your family,
rainwater applications are gradually increasing. This can
reduce water costs and also improve the environment as
well. Rainwater can be used for the following as a small
example:
Washing clothes
The water system in the garden
Potted plant water
Washing car
The following figure is to tell you how to run the rainwater
application system:
The rainwater is collected in the container and then
pumped to service water pipework via the pump M1. The
system allows the tank to also be filled from the drinking
water supply when there is not enough rain water.
Requirements for the Control System of Service Water
Pump
It should provide service water all day as needed. It should
also allow for the automatic addition of drinkable water
when required.
When switching to the drinkable water system, it can’t
interrupt rain water addition.
If the water level in the tank is too low, then the pump
cannot be turned On – Dry run protection.
