All these wall tools have a dedicated dust hood and valve. All the white PVC is from home depot. Its the cheap thin type pipe. The T's are the thicker platic type connectors used normally for thicker plastic tube. No glue was required on any pipe to tee connection. I used 4 sheet metal screws to fasten the valve to the tee and a bungie cord to fasten the gray flex hose to the valve. It's solid. I can move the tool away from the wall and it all stays together.
I screwed a 2x2 to the wall and used this cord rope to hang the pipe from a nail pounded in the top of the 2x2.
All the hoods, valves and gray flex tube is from Harbor Freight. 2 dust collector kits did it all.
