The Wagon Wheel Controls Water Flow Direction In Your Filtration System. It Engages The Internal Rotor And Gasket Inside The Valve To Switch Between Functions. It Also Provides Leverage For The Easy Turning Without Damaging The Valve.
Its great, our dogs love it. I suggest you highlight that the filter needs to be changes around every two weeks and you offer addition filters to be purchased. After reading the instructions I realized I needed to buy additional filters which I bought from Takealot.
