What is the purpose of the notches or teeth in an overflow box? Should I implement the same on my PVC pipe drain, not planning on adding an overflow box.
Planning on adding a large diamond screen on top of the pvc drain, the screen would be cylindrical shape and inserted inside the pipe to prevent any fish or objects from blocking the pipe
thanks
