FloJet Water Booster System - 12V, 4.5 GPM & 40 PSI - 02840100A

FloJet Water Booster System – 12V / 4.5 GPM / 40 PSI – 02840100A

The FloJet 02840100A Water Booster System is a high-performance 12V DC pump system designed to increase water pressure and flow for RVs, campers, boats, cabins, and light commercial freshwater applications. Delivering 4.5 gallons per minute (GPM) at 40 PSI, this booster ensures consistent, on-demand water pressure for multiple fixtures, including sinks, showers, and appliances.

Built with advanced diaphragm pump technology, the FloJet Water Booster System provides quiet, smooth, and pulsation-free water flow, improving comfort while protecting plumbing components from pressure spikes. Its integrated automatic pressure switch activates the pump when water is needed and shuts it off once the desired pressure is reached, offering efficient, hands-free operation.

Constructed with durable, corrosion-resistant materials, this system is engineered for long-lasting performance in demanding mobile and marine environments. The compact design allows for easy installation in tight spaces, making it ideal for RVs, campers, boats, or off-grid freshwater setups.

Key Features

• High Flow Capacity: Delivers 4.5 GPM (17.0 LPM) at 40 PSI, providing enough volume for luxury showers, galleys, and washdowns to run at the same time.

• Whisper-Quiet Operation: The accumulator tank stores pressurized water, meaning the pump only runs during high demand. This prevents the frequent on/off cycling that causes noise and wear.

• Pre-Assembled Design: The pump and tank come pre-wired and pre-plumbed on a sturdy, corrosion-resistant base for a professional and fast installation.

• Self-Priming & Run-Dry Safe: The pump can prime itself up to 6 vertical feet and can run dry for extended periods without damage to the internal diaphragms.

• FDA-Approved Materials: The tank features a food-grade butyl diaphragm, ensuring your potable water remains clean and taste-free.

Installation & Maintenance Tip

To ensure the smoothest operation, the air pressure in the accumulator tank should be checked once a season. Using a standard tire gauge on the tank's Schrader valve, ensure the pressure is set to 18 PSI (2 PSI below the cut-in pressure) when the water system is turned off and the lines are depressurized.
