Can I fill the toilet to the far left?

Look at your picture, your bathroom should be sunken, the floor of the bathroom is much lower than the indoor ground, you need to backfill yourself, if so, you can change the location of the sewer at will, as long as the slope of the sewer pipe and the drainage sequence of the sewer pipe are arranged reasonably, you must do waterproof after the backfill.

It depends on how far you move! It is better not to be too far away from the main sewage pipe for the toilet drain! It doesn't make much of a difference when you don't move too far!

As long as the pipes are in good contact with the water leakage, there is no problem! The main thing is the fear of clogging. That's a big problem!

Because you can't see anything in this picture, I can't tell you too much detail. If necessary, you can deduct my 877765924

This kind of drainage is not reasonable at all, how can there be drainage and sewage together. If you really want to separate dry and wet, I advise you to change all the horizontal pipes, cut off the straight pipes, replace the original 110 tees, with a 110 tee, a 110 anti-50 tee, and 110 telescopic joints, connect them in order with PVC glue, and then use 110PVC pipes to where you want, add 110 elbows [slightly higher than 110 tees], and then use 50PVC pipes to connect 110 anti-50 tees, and then connect them with 50 submersible bends to where you want. [Note:.]

You have to get the height well, the height of the elbow should be higher than the height of the tee, and the cement should be reinforced under the PVC pipe. 】

Is it the position you circled? Because it should be, look at the picture of your bathroom floor is at least 40CM lower than the door, with this height will not be poured up, unless your main pipe downstairs is blocked. A 110CM drain will not drain poorly.

As for water leakage, if the decoration master does not do it well, it may leak.

It can be installed in the position shown in your picture (left), just pay attention to connect the drain when installing.

Sigh! It's a joke!

It can be said that there is no common sense of drainage at all, and even the ventilation duct is not allowed to go this way.

First, the flow of water from the main vertical bar of drainage should be choked. (Reason: It is a 90-degree tee) Second, the 110 tube on the seat side should be choked back. (Reason: It is a 90-degree tee, and its 90-degree head change is not ideal).

The best way to change the position of the seat side drain is to change it in your lower space (but often few people in the lower class will agree, even if it is a standard change, it will not affect its use). Therefore, it is necessary to change the drainage position of the seat side, which is why it is recognized in the industry that it cannot be changed unless it is absolutely necessary (except for the case where the lower level agrees to change): if you add a horizontal pipe to move the position on this floor and raise the ground elevation (nearly 200 or so), this will not be acceptable.

And the drainage effect is greatly affected, it is easy to cause blockage, and the flushing force of the toilet should also be weakened.

The so-called dry and wet partition is actually meaningless for the toilets of general commercial houses. Because the total area is not large enough. Having said that, even if the area is large enough, because of this so-called separation of dry and wet, is it not worth it to risk serious drainage problems?

There is a toilet shifter, which can move the toilet by 5-15 cm, I personally think that 5 cm is acceptable, moving too much will affect the drainage, think twice!

In this case, do you need to use an open pipe for toilet drainage? Because the toilet drain neck is 100, it is impossible to groove on the ground, right?

It should be possible. Just change the sewer pipe yourself.
