1. Choose a good location: First, choose the location of the floor drain, generally choose the edge of the courtyard or a low-lying place. After the location is selected, it can be determined whether there are obstacles such as pipes or cables with testing instruments, so as not to damage other facilities.
2. Excavation: The pit at the excavation position of the floor drain should be at least 10 cm larger than the floor drain itself, so as to place a suitable drainage pipe.
3. Install cement cushion: lay cement cushion at the bottom of the pit to ensure the firmness of floor drain and prevent sewage from infiltrating into the ground.
4. Install the floor drain: put the floor drain in into the pit, put the drain pipe at the bottom of the floor drain and fix the floor drain.
5. Connect the drain pipe: connect the drain pipe to the floor drain and seal it with adhesive tape.
6. Filling: Fill the pit with soil and tamp it to ensure that there is no loose soil around the floor drain. Finally, you can add decorations such as paving stones or turf.
The above is the best installation method of courtyard floor drain, which can not only ensure good drainage in the courtyard, but also provide protection for the building structure.
