For the sunken toilet made by the developer, should the lower mouth of the drainage riser be a hidde

Generally do, the advantage of doing is that there can be double insurance, if the second waterproof leakage, the bottom of a waterproof, which greatly reduces the probability of bathroom leakage, and if the drain pipe leaks, the hidden floor drain can also be used as a layer of protection, it is not recommended to do, after doing a layer of leakage and multiple layers will suffer.

It's best to make a hidden floor drain so that your bathroom will look more beautiful, and at the same time, the hidden floor drain is rarely smelly.

As you all know, the general bathroom has two waterproof layers, one is the upper end of the floor tile layer waterproof, the other is the bottom end of the open to the outside of the waterproof, if the first floor or the sewer pipe leaks, then the bathroom filling layer, will the bottom edge of the waterproof and can not be discharged? Only deposits are deposited in it, which in turn leads to water storage in the caissons. Personally, it is very good to do a dark floor drain, which greatly reduces the occurrence of water seepage in the bathroom.

Double-layer pavement waterproof, double-layer anti-odor floor drain, if the project construction is done well, water seepage is basically impossible. Open the riser of the main sewer pipe, connect an anti-odor floor drain, and do a good job of deodorizing elbows to prevent waste water from flowing back.

Generally, the real estate chamber of commerce will do a waterproofing on the road surface, and the owners of the community will do a bottom waterproof again in the middle and later stages, and when they do the concealment of odor-proof floor drains, they will do the second layer of waterproofing, and after the backfill, they will do the third waterproofing, so that the three-layer maintenance, the possibility of water seepage is very low. If you do not do the second concealment of odor-proof floor drainage, only double-layer waterproofing, the upper end of the floor tile layer waterproof, and the bottom end of the real estate developer's waterproofing, if the upper end of the waterproof seepage, the filling layer of the bathroom will be due to the bottom of the waterproofing reasons, hoarding wastewater, long-term bathroom underground wet and cold, when a long time will cause the bathroom floor to be damp, tiles fall off, the middle and late maintenance must be dismantled ground decoration, maintenance costs are relatively high.

How is the home decoration effect of the bathroom, the key depends on the drainage pipe and waterproofing. Waterproofing, in fact, is our waterproof engineering construction, brushing waterproof architectural coatings, such as requiring everyone to brush at least 2 times above the waterproof architectural coatings, the relative height to ensure that the meters above, the key to do a good job in the sewer pipe mouth, pipeline junction. And the drainage pipes can be easily understood as our anti-odor floor drains.

However, everyone should know that after our downward toilet is backfilled or empty, it is not enough to have a surface odor-proof floor drain, because the water in the bathroom may seep into the bottom of the caisson through the road surface, or the water pipe buried in the caisson will cause damage and seepage, so the stored water will accumulate in the caisson.

At this moment, if the waterproofing layer is in place, the water will always smell in the caisson, and may even destroy the waterproofing layer, if the waterproofing layer is not in place, this water will gradually seep through the walls and concrete floor slabs, and harm the downstairs neighbors or other areas. Therefore, the downward moving toilet requires everyone to pre-bury the "secondary drainage" when decorating. Said secondary drain, in fact, is concealed floor drain, generally this anti-odor floor drain needs to be designed in the middle of the bathroom, and in the case of backfill empty frame, the outlet of this anti-odor floor drain should be designed lower, and should contain anti-water bend, ensure that the water storage can flow out from the secondary drainage outlet thoroughly.

In general, it is necessary to do a hidden drip, because this can reduce the occurrence of washing water leakage. It is also possible to drain water into the sewer pipe in the event of a leak.

I think if the developer is making a sunken bathroom drainage riser, it is necessary to make a hidden floor drain, which is not only beautiful, but also more convenient.

The lower mouth of the drainage riser should be made with a hidden floor drain, which can have a particularly good effect and look more beautiful.

In this case, the drainage pipe should be installed first, and if the drainage pipe mouth reserved by the developer is close to the ground, the ground at the bottom of the drainage pipe should be chiseled about 2 cm, because the drainage pipe must be connected in the space to be connected well.

Once chiseled, all drains can be installed and secured. Then it's time to do waterproofing.
