After the toilet sewer pipe is modified, it will be unblocked, will it be blocked often .

If it is not particularly affected, try not to change, the shifter is best not to use, the shifter is a bellows, easy to block. We generally solve it in two ways: one is to re-punch the hole, (if you install a toilet, don't sink the bay).

The second is to drill oblique holes (only suitable for 5-8CM displacement), and then do a good job of waterproofing on the inclined plane.

There should be no problem, I also changed, at present, it is okay, as long as the decoration company does a good job of plumbing, but the slow drainage should be obvious, this depends on you, first of all, you must understand that the toilet 99% of the time only go in by yourself, if you are not forced to do so, try not to change, I am because of feng shui problems, the upstairs toilet is facing the kitchen downstairs, and it has to be changed.

If it is made of PVC material, after hot melt bonding, you must test the water, and the nozzle may be deformed or even sealed if the water is slow.

It is best to use PVC pipes for sewers, and there should be no burrs at the joints. After installation, do a water test, and it will generally not be blocked after success.

In principle, it cannot be changed: if it has to be changed, it must be controlled within 1.5 meters, and the toilet cushion is 15 20 cm high. More than four meters··? The bathroom is quite big (.).
