You can only cut out your wall and then repair it.

Make a slope with a percussion drill in the place of the pit pipe.

Change the toilet, there is a small pit distance toilet.
It is said that it is 30 cm, and it has 2 3 cm of adjustment space before and after, and the difference between two centimeters has no effect, so it can be installed, rest assured. >>>More
This pit spacing is a bit large, and it is also nice to leave a gap of two or three centimeters behind the toilet when installing.
A 330 toilet is required.
GENERALLY, THE WALL SPACING OF THE LOWER DRAIN TOILET IS DIVIDED INTO 305MM, 330MM, 400MM AND 420MM, AND MOST OF THE TOILETS ON THE MARKET ARE 305MM AND 400MM. Generally, the toilet wall distance is smaller than the actual wall distance of the bathroom, and 20mm is reserved in the actual operation, and 20mm is the distance of the reserved wall tiles. Then the actual distance from the center line of the toilet drain (diameter 110) to the wall is 320mm or 420mm. >>>More
The pit spacing is the distance between the center of the toilet drain and the wall.
It can be installed, but the flushing effect will definitely be affected, and it is easy to clog, so I personally recommend replacing it with a toilet with a 300 pit distance!
