Your water seepage problem is more complicated, first of all, the toilet and sewer pipe are not installed tightly, resulting in the overflow of toilet water, and the only way to deal with it is to reinstall it. The second is that the waterproofing of the bathroom is unqualified, resulting in the water leakage of the ground to the downstairs, the waterproofing is not done, and it is difficult to re-do the waterproofing, so you can only apply some waterproof glue around the sewer pipe as a remedy. FYI.
It is definitely not possible to wipe with glue, like this I generally can reconnect if I can reconnect, and if I can't reconnect it, I will drop the section of pipe in front of the leakage, and carefully shave out the pipe in the pipe fittings with a razor, and reconnect it with a live joint. It should be noted that you must be careful when shaving off the 110 old pipe in the pipe fitting, otherwise it will be more troublesome if the pipe fitting is damaged.
Before the plumbing is installed, a hole is made in the structural panel of the restroom preparation and the hole is larger than the diameter of the drain pipe. If the size of the drainage pipe is DN110, the diameter of the hole in the structural plate will be greater than 11cmTherefore, there will be a void between the drainage pipe and the structural slab (i.e. cast-in-place concrete slab), and when the filling and sealing treatment of the cavity is not in place, the problem of water leakage will occur. >>>More
No, the anti-bend must be installed at the mouth of the toilet, the floor drain, if it is installed in the middle, then the section of the pipeline from the floor drain to the anti-bend will produce dirt and smell after a long time.
It can only be treated with PVC glue.
