The water in the kitchen is always blocked. Is it feasible to divert the toilet? Is there still a four-proof floor drain that can block the sewer pipe?

If the main drainage pole of the kitchen and the main drainage pole of the bathroom are separated and the horizontal distance is not long, you can consider shunting.

What is the main bar in this bathroom now? If it works normally, consider shunting.

Attention to diversion: First, the horizontal pipe should have some slopes as much as possible. Try to walk the exposed pipes against the wall, and don't hide them. There is nothing ugly about white PVC pipes, which is very important for future maintenance.

Second, the kitchen sink drain pipe: it should be replaced by a basket, and its purpose is to discharge sewage as close as possible to water without larger particles. Otherwise, your horizontal pipe will have problems for a long time. This is a sink drainage structure adopted by developed countries for a long time, and it is a set of leaky baskets with different eye diameters, and finally the water without particles is discharged. If every household uses such a drainage structure, the main reinforcement will not be blocked even if there are some design problems.
