I want to put a utility sink in the garage so my mom can wash her dogs. I was thinking I can put T-valves on the water conection to the washing machine. Now about the drain ... the washing machine drain hose goes up and sits in this open pipe coming out of the wall 3.5' off the floor...it's sticks out at an angle. How do I connect the drain from the utility sink to this pipe? Much thanks for any advice.
