What should I do if the toilet is not made of secondary drainage tiles and is always wet

You can temporarily block it and take it off after repairing!

Now the housing bathroom is basically sunken, and this kind of bathroom will think of backfilling it when it is decorated, but I think it is better to use overhead. Because it's more practical and has a lower budget. Let's talk about the differences. >>>More

Secondary drainage is a drainage method to prevent leakage of water pipes buried in the bathroom and water seepage from the floor to the owner's house downstairs. Because the toilet will leak into the caisson in the case of long-term use, and then accumulate in the caisson, the cement will more or less leak downstairs in the long-term soaking, and the secondary drainage just solves this problem. When decorating, the owner should pay attention to the water pipe laid in the room and it is best to seal it with asphalt, so that even if the interface position is not completely sealed during construction or has been used for a long time, it will not leak. >>>More

To decorate, ask a designer to design the drainage. During the construction, drill holes, lead sewer pipes and water supply, and do waterproofing.

If this is the case, the first thing to do is to check whether the drain outlet of the sewer is blocked. If this one drain is blocked, the water below will not be able to flow into the drain completely, but will be squeezed up again. >>>More
