How to Test for Water in Your Oil Tank

Water in an oil tank may occur due to condensed moisture or a leak from a crack or an ill-fitted filler cap. When a sufficient amount of water enters the tank and spills into the fuel line, it prevents the boiler from functioning since the kerosene fuel becomes contaminated and water does not burn. How to test for water in your oil tank? the process is actually quite simple and only requires a few minutes of your time.

Water Finding Paste for Oil Tanks

To check for water in your heating oil tank, you will require two items: water finding paste and a long stick or pole that can reach the tank’s bottom. The widely used water finding paste available for purchase online is “Kolor Kut Water Finding Paste,” priced at £13.99 on Amazon.

How to Test for Water in Your Oil Tank:

1) Apply a thin strip of paste on the bottom 6 inches of a stick or pole.

The majority of outlet valves on oil tanks have a height of approximately 50mm from the bottom of the tank. This design allows any water, dirt, or contaminants to settle at the bottom without entering the fuel line. If, after conducting a water test on your tank, you discover more than 1 inch of water as indicated by the paste, there is a strong likelihood that the water is responsible for the problem with your heating system.

How do Remover Water From an Oil Tank?

To remove water from an oil tank, you will need a fuel transfer pump and multiple 20-liter drums to collect the contaminated oil. The amount of water present in the tank will determine the volume of oil you need to drain.

Start by using the fuel transfer pump to drain the contaminated oil into the drums. You will notice that the liquid going into the drums appears dirty and similar to water. Once the colour changes to amber, indicating the presence of kerosene oil, stop the pump and retest using water finding paste. If the paste does not change colour, it means all the water has been removed. However, if the colour remains red, you will need to repeat the process of draining more contaminated oil until all the water has been removed.

After removing the water from the tank, clean the filter and drain the fuel line to eliminate any remaining water. There is a possibility that the fuel pump on the boiler may be damaged, but you can test this by running your boiler.
