Best way to find out is to ask the person you got the filter from, to me that T in between the canisters doesn't make any sense.Hello can anyone explain what this valve is for? Its not the flush valve in the back of the unit, its aditional. I purchased the filter second hand.
thx
The black goes to a union connected to the black waste.where does the black tube on the back of the valve go? What is it connected to?
