Is it okay for a siphon toilet not to be equipped with a flange ring?

All toilets are installed, and it doesn't matter if the flange siphon is not siphoned.

Answer 1: No, the bottom of the toilet still needs to be equipped with a flange ring. The flange ring is also called the anti-odor ring, which is mainly installed at the bottom of the toilet bowl and is used to connect the part of the sewer. If installed, it can block the odor from the sewer, and it also seals very well.

2. After a long time, the flange ring will also be subject to different degrees of wear, its role will slowly disappear, and it will be prone to water seepage at the bottom, and even some peculiar smells will appear, so the installed Malan ring must be replaced regularly, so as to ensure its effect. When buying flange rings, you should also pay attention to choose slightly better quality, don't be greedy for cheap, buy some inferior products, otherwise there will be no effect, and it will bring us endless troubles later.

It can be installed and used, but it should be noted that the toilet downhole and the drainage pipe should be perpendicular and not offset, and the drainage pipe should protrude 2 cm from the floor tile, otherwise it is easy to seep!
