Does the toilet downpipe have to be lower than the tile finish?

Today, let’s talk about the reserved length of the toilet sewer pipe. A few days ago, an owner left a message to me, saying that his master bricklayer told him that the toilet sewer pipe must be lower than the finished surface of the tiles.

This statement is obviously wrong. If you want to get a correct answer, you can ask the after-sales service or the manufacturer of the toilet.

I have also asked many masters who install toilets on this question. Most masters will say that the toilet sewer pipe is preferably higher than the finished surface of the tile, and it doesn’t matter how high it is.

To install the toilet, first cut off the pipe more than one centimeter above the finished surface of the tile, then install the sealing ring and then install the toilet.

The structure of the sealing ring, the diameter of the pipe facing down is relatively small, it is to be inserted into the toilet water pipe, and the side facing up is relatively large, which is to be connected to the toilet.

If the sewer pipe and the sealing ring are tightly connected together, the water discharged from the toilet directly enters the sewer pipe. In this case, even if the periphery of the toilet sewer pipe is not waterproof, there will be no water leakage.

If there is a gap between the toilet water pipe and the sealing ring, part of the water flushed from the toilet will flush to the outside of the pipe every time, and under the effect of waterproofing, it will not leak in a short time.

After a long time, who dares to say? The pressure of each flush of the toilet is very large. Under this pressure, how long can the original waterproofing last?

This situation generally does not appear in rough housing, and developers will reserve a relatively high position for the sewer pipe.

The most common situation in this situation is the renovation of the bathroom. As long as the sewer pipe is not raised, after the tiles are pasted, the sewer pipe must be lower than the finished surface of the tile.

The reason why some bricklayers do not recommend raising the sewer pipe is because the tiles on the ground are not easy to lay after the heightening. I have seen some bricklayers deliberately cut down the originally high sewer pipe to facilitate the installation of tiles. , can only say that this is too irresponsible.

If this happens at home, the solution is very simple. In the water and electricity stage, you can directly add a direct, connect a pipe to the top, and spend 3 yuan and 5 cents to get it done. If the tiles have been installed, buy a 110× 100 shrunk, just smash the tiles around the toilet drain pipe a little and insert it directly.

Both of these methods only cost a few dollars, and the effect is very large.
