WATER WATCH

WATER WATCH

Invented, engineer, and manufactured in Australia, Water Watch is a cutting-edge 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 systems, approximately 85% of the fuel circulates through the system and returns to the tank each operational hour. This high flow rate, combined with elevated temperatures and pressures, makes these systems particularly susceptible to damage from water contamination.

Installing an additional fuel filter or water trap alone may not provide sufficient protection against water-induced damage. The Water Watch system effectively separates free water from the fuel and promptly alerts the driver through visual and audible signals when water is detected. Notably, the alarm activates upon accumulating just 5ml (1 teaspoon) of water, enabling the driver to address the issue before any harm occurs.

In contrast, conventional water traps lacking an alarm can allow water to build up unnoticed, potentially recirculating through the fuel system and causing damage. Often, these traps are only checked during scheduled vehicle maintenance or at irregular intervals, by which time significant damage may have already occured.

Implementing the Water Watch system ensures early detection and removal of water, safeguarding the integrity and performance of your common rail diesel engine.

HOW DOES IT WORK

Fuel enters the Water Watch through a conical section and passes through a narrow gap along the edge.

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

Due to their higher density, water and particles are separated from the fuel by centrifugal force, which pushes them out of the fuel.

The system operates without moving parts, meaning there is no resistance to fuel flow.

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

The Water Watch is installed after the fuel tank but before the original manufacturer's filter.

IS THERE AN INFORMATION BOOKLET?

Yes, you should have received a booklet when the Water Watch unit was installed. However we understand these can get damaged or lost. A copy can be found on our instructions page.

WHY IS WATER BAD IN A FUEL SYSTEM

Dependent on the volume of contamination, water can cause immediate or prolonged damage to your fuel system. Water reduces lubricity and causes fuel components to wear, corrode, and rust from inside the fuel system. Subsequently, creating a breeding ground for bacteria and fungi, resulting in a dirty sludge.

HOW DOES WATER ENTER FUEL?

It can happen numerous ways such as:

  • Fuel transfer from one tank to another, for example a fuel tanker at a service station transferring fuel to underground storage and where the fuel mixes with air and water.
  • Condensation build-up whilst in storage
  • Seepage from groundwater or storage tank leaks during re-fuelling or wet weather.

DO MANUFACTURERS RECOMMEND WATER WATER & WILL IT VOID THE MANUFACTURERS WARRANTY?

Several manufacturers have approved Water Watch as an aftermarket product. Since it does not restrict fuel flow or affect fuel system operation, it will not void your manufacturer’s warranty.

CAN I TRANSFER MY WATER WATCH TO ANOTHER VEHICLE?

Yes, subject to compatibility. Please contact us if you are unsure.
