The first possibility is that the installation is not good, and the second is that something inside you has fallen down.
Your boss is too exaggerated, isn't it? If you don't let someone take you down, you can go straight to the school, ask the master for advice, or go to the next one that someone else does. Combined with design specifications.
Drainage pipe diameter: DN100 diameter is required for toilets, DN75 is required for more than 3 urinals, and DN32 is required for washbasins. >>>More
