Introduction
The Flojet Quad DC Water System Pump with Bypass is designed to provide reliable and consistent water pressure for various applications, including marine, RV, and off-grid systems. This 12-volt pump features a 3.3 GPM flow rate and includes an integrated bypass, which helps to reduce cycling and provide smoother flow, extending the life of the pump and system components. It is self-priming up to 2.4 meters (8 feet) and is built with durable polypropylene materials for long-lasting performance.
Safety Information
Please read and understand all safety instructions before installing or operating this pump. Failure to do so may result in injury or damage to the product.
- Always disconnect power before performing any installation, maintenance, or troubleshooting.
- Ensure proper ventilation around the pump to prevent overheating.
- Do not pump flammable liquids or use in explosive atmospheres.
- Protect electrical connections from water and moisture. Use appropriate marine-grade wiring and connectors if used in a marine environment.
- Wear appropriate personal protective equipment (PPE) during installation and maintenance.
- This pump is designed for intermittent duty. Avoid continuous operation for extended periods without proper cooling.

Image: The Flojet Quad DC Water System Pump, black in color, shown with two quick-connect fittings. The pump features a cylindrical motor housing and a pump head with inlet and outlet ports. The label on the motor indicates "FLOJET WATER PUMP MOD: R4305 S/N: 05167007 VOLTS: 12 VOLTS DC AMPS: 7.0 AMPS FLOW: 3.3 GPM PRESS: 25 PSI".
Setup
Mounting
Mount the pump in a dry, accessible location, protected from direct sunlight and freezing temperatures. The pump can be mounted in any position, but it is recommended to mount it with the pump head lower than the water tank to aid in priming. Use appropriate fasteners to secure the pump through its mounting feet.
Plumbing Connections
- Identify the inlet and outlet ports on the pump head. The inlet is typically marked with an arrow pointing towards the pump, and the outlet with an arrow pointing away.
- Connect the quick-connect fittings to the pump ports. Ensure a secure, leak-free connection.
- Connect the inlet side of the pump to your water supply tank using appropriate flexible hose or tubing. Use a strainer/filter on the inlet line to prevent debris from entering the pump.
- Connect the outlet side of the pump to your water distribution system (e.g., faucets, shower).
- Ensure all plumbing connections are tight to prevent air leaks, which can affect pump performance and priming.
Electrical Connections
This pump operates on 12 Volts DC. Ensure your power source matches this requirement.
- Connect the positive (+) wire from your 12V DC power source to the positive terminal of the pump.
- Connect the negative (-) wire from your 12V DC power source to the negative terminal of the pump.
- It is highly recommended to install an appropriately sized fuse (e.g., 10-amp) in the positive power line, close to the power source, to protect the pump and wiring.
- Ensure all electrical connections are clean, secure, and protected from corrosion.
Operating Instructions
- Once plumbing and electrical connections are complete, ensure the water tank has sufficient water.
- Open a faucet in your system to allow air to escape.
- Apply power to the pump. The pump will begin to run and self-prime, drawing water from the tank.
- Allow the pump to run until a steady stream of water flows from the open faucet, indicating that all air has been purged from the system.
- Close the faucet. The pump should build pressure and then shut off automatically.
- When a faucet is opened, the pressure will drop, and the pump will automatically restart to maintain pressure.
Pressure Switch Adjustment
The pump features an adjustable pressure switch. If the pump is cycling rapidly or not maintaining consistent pressure, the pressure switch may need adjustment. To adjust, locate the small cap on the end of the pump head (opposite the motor). Carefully remove this cap to expose an adjustment screw. Turning the screw clockwise will increase the cut-off pressure, and counter-clockwise will decrease it. Make small adjustments and test the pump's operation after each adjustment until desired performance is achieved. Replace the cap securely after adjustment.
Maintenance
- Regular Inspection: Periodically check all plumbing and electrical connections for leaks, corrosion, or loose fittings.
- Inlet Strainer: If an inlet strainer is used, clean it regularly to prevent debris from restricting flow and damaging the pump.
- Winterization: In freezing climates, the pump must be drained or winterized with non-toxic RV antifreeze to prevent damage from freezing water. Disconnect inlet and outlet lines and allow water to drain completely, or pump antifreeze through the system.
- Storage: If storing the pump for an extended period, ensure it is clean, dry, and stored in a non-freezing environment.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not run. | No power; Blown fuse; Loose wiring; Motor fault. | Check power supply; Replace fuse; Secure connections; Contact support if motor is faulty. |
| Pump runs but no water flows. | No water in tank; Air leak on inlet side; Clogged inlet strainer; Pump not primed. | Fill tank; Check inlet connections for leaks; Clean strainer; Ensure pump is primed (open faucet). |
| Low flow or pressure. | Clogged strainer; Kinked hose; Low voltage; Worn pump head. | Clean strainer; Straighten hose; Check voltage; Contact support for worn parts. |
| Pump cycles on and off rapidly. | Air in system; Pressure switch needs adjustment; Small leak in system. | Purge air by opening faucets; Adjust pressure switch (see Operating Instructions); Check for leaks in plumbing. |
| Excessive noise. | Vibration; Air in system; Debris in pump. | Ensure pump is securely mounted; Purge air; Inspect for debris (disconnect power first). |
