Method one, install it yourself

There are two ways, one is to operate at home, but the ground needs to be raised by about 1 dm. Make a hole at the root of the kitchen riser, and then connect the drainage branch pipe, where a slow slope is needed to facilitate the drainage of the floor drain.

There is another way, you don’t need to raise the floor of your own kitchen, but you need to negotiate with the downstairs to install the drainage branch pipe of the floor drains downstairs and connect it with a drainage tee, which is more convenient.

Method two: install a check valve in the pipeline

If you don’t want to troubleshoot the piping design, there is a simple way to install a check valve on the kitchen drain branch pipe, but the quality of the check valve must be strictly controlled. Of course, it is not so convenient to clean the ground normally. .

Although it is not mandatory to install floor drains in the kitchen in the related regulations of building houses, it is still necessary to be able to take precautions and clean up and save a lot of trouble. What do you think?
