How the System Works

The Whaleflo BW4003A is designed to pump purified water from a standard 5-gallon bottled water container and deliver it under pressure to:

• Coffee & tea brewers
• Refrigerators & ice makers
• Chilled water taps
• Drinking water faucets

When the suction wand is inserted into the bottle, the built-in float switch automatically turns the pump on. As water is drawn, the pump intelligently adjusts flow and pressure to meet demand. Once the bottle is empty, the float switch shuts the system off automatically.

A built-in back-flow prevention valve ensures no water spills or drains back into the bottle during changes, keeping the system clean and safe.

Designed for Convenience & Reliability

• No plumbing required
• Consistent pressure delivery
• Quiet, automatic operation
• Ideal for locations without a direct water line

Perfect for espresso machines that require stable pressure, such as prosumer and commercial coffee equipment.
