    Interesting fact

    Did you know that if an air pump is turned off or you have a power cut resulting in the air pump turning off the water can travel up an airline to nights up to and beyond 1 meter above the water level of your pond resulting in your expensive air pump being destroyed. Utopia Koi highly recommends the use of non return valves to prevent such an accident that can be easily avoided
