3.2.2. Drilling the piping hole (Fig. 3-3)
s
Use a core drill to make a hole of 90-100 mm diameter in the wall in the
piping direction, at the position shown in the diagram to the left.
s
The hole should incline so that the outside opening is lower than the inside
opening.
s
Insert a sleeve (with a 90 mm diameter and purchased locally) through the
hole.
Note:
The purpose of the hole’s inclination is to promote drain flow.
