WATER WATCH

A WATER IN FUEL ALARAM SYSTEM

Invented, engineered and manufactured in Australia, our Water Watch is a water and sediment trap system for common rail diesel fuel systems. It proudly carries the Australian Made and Owned certification and licence.

In common rail fuel system, approximately 85 per cent of fuel circulates through the system and returns to the tank each operational hour. The high flow rate, combined with elevated temperature and pressure, makes these fuel systems particularly susceptible to damage from water contamination.

Our Water Watch system effectively separates water and particle from fuel and promptly alerts the driver through visual and audible signals when detected. It alerts with the accumulation of 5ml (1tsp), enabling the driver to address the issue before damage occurs.

Remember, filters are not designed to stop water, they only collect particle, hence installing a secondary filter can not protect your fuel system any better than the factory can.

    WATER ENTERS

    Condensation, contamination or poor fuel storage can introduce water into diesel and your factory fuel filter won’t stop it.

  • Water Watch Detect Icon

    WATER IS DETECTED

    Fuel passes through Water Watch and creates a vortex separating the water and particle.

    The Water Watch sensor detects as little as 5ml of water and alerts you through audio and visual.

    Unscrew the sensor, drain the Water Watch, and continue your travels.

Diesel enters the Water Watch through a conical section and passes through a narrow gap along the top edge of the housing.

It then flows radially toward the centre and exits the unit.

Due to their higher density, water and particle are separated from the fuel through centrifugal force, pushing them out of the diesel.

The diesel's flow rate generates the necessary force to efficiently separate water and particle, keeping them at the bottom of the bowl, beneath the fuel flow.

Water Watch operates without any moving parts of filters, meaning there is no restriction to the fuel flow.

WHERE DOES IT SIT?

Water Watch is located in the supply line between the fuel tank and the factory fuel filter. Fuel in common rail diesel is also used to cool the system and can circulate up to approx. 70 litres per hour.

HOW DO WE COMPARE

Water Watch is located in the supply line from the fuel tank and before the factory fuel filter. Fuel in common rail diesel is also used to cool the system, so it circulates through the system up to 70 litres per hour.

Separate and remove water?

βœ“ Yes - designed for common rail diesel fuel systems and separates water from the fuel.

βœ• No - water under pressure will go through the filter.

βœ• No - water under pressure will go through filter.

βœ“ Yes - works in modern vehicles but designed for low fuel flow rates.

Does it remove particle?

βœ“ Yes - removes all particle that is heavier than diesel. Bowl allows for easy inspection.

βœ“ Yes - captures particle that is larger than the filter micron. A filter micron that is lower than the factory fuel filter will create a suction restriction.

βœ“ Yes - very good for particle removal.

βœ“ Yes - needs regular maintenance to ensure there isn't a build up. You cannot see into the unit and excess will flow through the system.

Does it restrict fuel flow?

βœ“ No restriction - there is no filter to create a physical barrier or become clogged.

βœ• Yes, causes restriction - creates a barrier from the paper medium and reduces fuel flow rate.

βœ“ Yes - however the vehicle is designed to accommodate the restriction caused by the factory fuel filter.

βœ“ No restriction - there is no filter to create a physical barrier or become clogged.

Does it have an alarm system?

βœ“ Yes - highly sensitive alarm that activates with as little as 5ml.

βœ“ Yes - water will collect when fuel pressure and flow rate is low (restricted) and relies on gravity to work.

βœ“ Yes - water will collect when fuel pressure and flow rate is low (restricted) and relies on gravity to work.

βœ“ Yes - sensitivity of alarm can vary from poor to good.

How much water is collected before alarming?

5ml or 1tsp of water.

Approx. 30-200ml of water.

Approx. 50-200ml of water.

Approx. 50-100ml of water.

Does it work under high fuel flow and pressure rates?

βœ“ Yes - designed to for both.

βœ“ No - causes a restriction to the fuel system.

βœ“ Yes - designed for the vehicle.

βœ“ No - can leak when there is high flow and pressure rates.

Does it work under high temperature?

βœ“ Yes - designed for extreme temperature.

βœ“ No - plastic components are known to discolour and distort under high temperature, resulting in leakage.

βœ“ Yes - designed for the vehicle.

βœ“ Yes - generally not affected by temperature.

Is maintenance required?

βœ“ No - requires no maintenance or replacement parts.

βœ• Yes - requires regular maintenance.

βœ• Yes - requires regular maintenance.

βœ• Yes - requires regular maintenance.
