How does the AcquaSaver Work?

The AcquaSaver® Valve will always prioritize the use of rainwater over mains water when rainwater is available and will automatically switch over to mains water in the event of the rainwater tank running low or electrical failure

When rainwater has been replenished or power has been restored to the pump, the AcquaSaver valve will automatically prioritize back to rainwater.

The pump is only active when rainwater is being drawn from the water tank, it does not operate when the AcquaSaver Valve has switched to mains position.

The pump controller starts and stops the pump when it detects a demand - for example flushing a toilet or using a washing machine.

The operating mechanism of the AcquaSaver Valve is a unique patent design, it works by hydraulic water pressure created by the pump to close one inlet fully before opening the other inlet. This ensures an extremely reliable mechanism using few moving parts and no electronic components and no energy consumption.

Customer Reviews

"Dear 4 Pumps,

I purchased a pump off you mid Feb. Just wanted you to know best value for dollar ever. The little pump is working very hard in a factory pumping liquid with about 20% solids and hasn't missed a beat. Great pumps, thanks."
