Generally speaking, kitchens and bathrooms need to be equipped with floor drains, mainly to facilitate drainage. How can the kitchen drain without a floor drain? Bian Xiao takes everyone to understand it.

Newly built commercial houses are basically a drainage riser in the kitchen, and then a tee is connected from this drainage riser. The height of this tee is about 30 cm from the ground. A drainage branch pipe is connected from the tee pipe, which is the reserved water inlet of our kitchen sink. Others don't have any sewer connections.

Therefore, if there is no floor drain in the kitchen, the solution of drainage is to wash a hole in the ground with a diameter of about 75 mm, and then connect a sewer pipe under the roof downstairs. This sewer pipe should be connected to the riser of the kitchen, and the connected part is under the roof of the kitchen downstairs.

Try to install a floor drain in the kitchen. Installing a floor drain has many advantages. You can prevent running water when no one is at home. If there is running water, you can take it away along this floor drain without causing too much damage to the downstairs.
