The Real "Water Watch" Protection System

Lifetime warranty!

Accurately detects water in diesel fuel, at high flow rates of modern Diesel Fuel systems 

5ml will set off the audio and visual alarm.

 Note:  Common Rail Fuel Systems typically have high flow rates of 50 -60 litres per hour through the system for cooling and lubrication.

Protecting your Common Rail Diesel Fuel System from costly contamination repairs

No filters to restrict fuel flow or vehicle performance.  Filters can’t stop or separate water under even light pressure or suction.

  •   Water Watch has a patented electronic sensor, not a float or electrode system, so function is not reduced by the presence of particulates or sludge in the fuel collecting around the water detector.  
  •   Patented Diffuser system is designed to effectively remove water and contaminants from fuel at high flow rates.  The Sensor is easily removed to drain off contaminants held in  the glass bowl away from the main fuel flow.
  • It’s not a sedimenter, so you’re not relying on the water and particulates to settle into a bowl for the alarm to work (which, is often too late for your fuel system; contamination happens very quickly with the high flow rates in Common Rail Diesels).
  •   All components of Water Watch are designed to operate at high temperatures, high pressures and high fuel rates used by Common Rail Diesels.  No distortion or malfunction of components.  Water Watch components have a lifetime guarantee.
  • No regular maintenance or replacement required.  Visual checks will let you know the quality of your fuel and you can see any contamination. 
  • Water Watch is available to fit any common rail diesel fuel system from small cars through to larger vehicles, including industrial and marine applications.
  • Bracket kits are available to fit most popular common rail diesels – making Water Watch very easy to install.
