    Techniques For Sanitising Caravan Water Tanks

    Sanitising your caravan water tanks is a crucial step to ensure clean and safe water for your travels. Here are some effective techniques to sanitise your caravan water tanks:


    Chlorination is a widely used method for disinfecting and purifying water in caravan tanks. It helps eliminate harmful bacteria, viruses, and other microorganisms, ensuring that the water remains safe and suitable for use.

    Ultraviolet (UV) light

    UV light utilises a specific wavelength of light, typically in the range of 254 nanometres, to target and disrupt the DNA of microorganisms present in water. This process effectively neutralises harmful bacteria, viruses, and parasites, rendering them unable to reproduce and causing them to become inactive.
