Although you don't have a picture, but I understand a little bit after listening to what you said, isn't the opening of the 110PVC sewer pipe under your floor tiles? If so, I suggest smashing the floor tile and calling the plumber to pick it up and do the waterproofing. If you smash it, you can do waterproofing directly there, but if you want to see if it leaks, you have to see if the waterproofing is good or not!

You don't have a picture, you don't know what you're going to do.

Cracked? Find a pipe hoop to bond it with PVC glue, and if you are afraid of falling something, you can find a large plastic bag to fill the newspaper and plug it, and it is not difficult to pay attention not to damage the waterproof.

According to what you said, there is no problem, the outer diameter of the toilet is also smaller than the inner diameter of the pipe you are connected to, no problem, don't worry. In fact, it should be no problem if you don't connect this section of the pipe, when you buy a toilet, you ask them for an anti-odor flange, which is a kind of butter-like thing that can seal the toilet and drainage, most of the toilets are equipped with one, if you don't give it to you, you really can't buy one yourself.

It is feasible, but you have to pay attention to the fact that when you take it, you must use professional watering (water supply and drainage glue) to stain it well For insurance, then put a circle of glass glue on the outside and then install the toilet After the toilet is installed, you still have to play a circle of glass glue below, these things are not expensive For the sake of insurance, do more.

I took a closer look at the photos and the biggest problem with your sewer pipe is that long crack! When the toilet is in use, there is a high chance that this crack will leak water downstairs along the joint between the sewer pipe and the floor slab.

What you may not know is that when a plumber installs a toilet, he saws off the PVC pipe that is higher than the floor so that the end of the pipe is in the same plane as the floor tile. So your cannula solution is not feasible.

In fact, there are a variety of effective plugging and waterproofing methods for this kind of simple and clear leakage point, such as pouring plugging mortar, waterproof glue, foam glue, etc., or simply using the most primitive waterproof asphalt to paint.

There is no pressure in the sewer, and it is relatively easy to plug the leakage, and there are many times when you don't care about it, and it will not leak when you use it.

If the waterproofing is in place, it doesn't matter at all, it doesn't affect the toilet installation.

Now such a tube can be used orally.

Just make it the same height around with cement.

THE OUTLET OF THE TOILET IS ONLY 70MM

It should be no problem, the toilet bottom port has not yet reached 10CM. I installed the toilet myself.

Hahaha、、、 you're too careful, right, what's the matter? It doesn't affect the toilet at all. Too much to worry about.
