Can a non-sinking toilet be changed into a sewer pipe? If so, how to operate it?

Non-sinking toilet is a different kind of floor drainage toilet. In principle, some indoor branch pipes cannot be replaced in such toilets. However, changes can be made appropriately with the consent of lower-level residents. Irrigation test should be carried out after reconstruction. The specific method is to prepare more than 20 liters of water and quickly pour it into the toilet at one time, so that whoever is in the toilet will be close to full. Then check whether there is any leakage in the reconstructed pipeline on the next floor. Don't look, every joint is pressed with paper towels. As long as there is no trace on the tissue, it is qualified.
