How to do secondary drainage in the bathroom

1. Open holes and install drainage pipes. We first need to make a hole in the main drain pipe in the bathroom, and then install the drain pipe. The mouth of the drainage pipe should be the same height as the original sunken layer waterproof layer, and the other end should be inserted into the main drainage pipeline, and the PVC glue should be used to bond firmly.

In addition, it should be noted that the opening needs to be polished and smooth, and there should be no burrs. The part that is inserted into the main pipe (riser) of the drainage pipe should not exceed the pipe wall by more than 3mm.

2. Leveling of the sinking layer. Subsequently, we leveled a slope according to the lowest point of the installed drainage nozzle, so that the stagnant water could flow smoothly to the secondary drainage nozzle of Qingyuqing, so that it could be drained smoothly.

3. The sinking layer is waterproof. After the leveling is done, brush it twice to make it waterproof.

4. Pipe routing and overhead partition. When making partitions, of course, you need to consider the location of the pipes.

5. Backfill, rebar and concrete. If you need to do backfilling, you generally use ceramsite to backfill, of course, there are many families, directly do overhead, do not do backfill, it is also possible.

The advantage of ceramsite is that it has good drainage, even if there is a leakage, the water can quickly flow to the bottom of the sinking layer and be discharged through secondary drainage, while some families use cinder backfill, which is not conducive to drainage.

6. Brush waterproof and plain cement slurry. After the concrete is done, this is the ground floor of the bathroom, and then we need to brush the floor of the bathroom with waterproofing and tear it down twice. Then make plain cement slurry to protect.

The correct construction idea of secondary drainage in the bathroom.

First of all, you can make a hole in one corner of the bathroom, and then insert a water pipe in it, so that you can make a secondary drainage, which is very beautiful.

How to do the secondary drainage of the bathroom mentioned here is mainly for the secondary drainage inside the caisson of the sunken toilet? For the secondary drainage inside the caisson, we must first understand its characteristics, because only after understanding the characteristics of these caissons and the characteristics of the inner wall of the caisson can we make reasonable drainage.

Divide the caisson into several 400*400 lattices. Many people don't do this step, in fact, this is a very important step, with such a load-bearing partition, the concrete layer above will not fall. Otherwise, after a few years, the bathroom floor will sink, crack and leak.

A drain is installed at the lowest point of the floor of the caisson structure. It is important to note that the drain we install must be at the lowest point of the caisson floor to drain water effectively. In addition, the floor drain should have an effective water seal and some measures to prevent backwater.

In this way, after we complete the installation, we can effectively ensure the secondary drainage of the sunken toilet.

<>1. Install the drainage pipe: install the drainage pipe after the hole is opened in the main drainage pipe of the bathroom, and pay attention to the drainage pipe mouth should be the same height as the waterproof layer of the original sinking layer. 2. Sinking layer treatment:

Make a slope according to the leveling of the drainage pipe mouth. After that, brush the waterproof paint twice. 3. Pipe routing and partitioning

When making partitions, the location of the pipes laid should be fully considered. 4. Use ceramsite with good drainage for backfilling, and then lay steel bars for concrete treatment. 5. Finishing work:

Brush the bathroom floor twice and do plain cement slurry treatment after waterproofing.

The following are the common practices for secondary drainage in general stool toilets:

Toilet drain: Toilets are usually connected to drains on the ground. Use an S- or P-bend to connect the toilet to the sewer. In this way, when the toilet is flushed, the waste water enters the sewer system through the elbow.

Wash basin drainage: The wash basin is usually connected to the drain of the sewer. Use a curvilinear drainage pipe to connect the basin to the sewer.

Shower drainage: Showers usually have a drain and are usually located on the ground in the shower area. The drain is connected to a system of drain pipes, through which wastewater is channelled to the sewer.

How to do secondary drainage in the bathroom, the master will teach you to do this step, and there is no trouble in moving in.

1.Drill holes and install drains. We first need to make a hole in the main drain pipe in the bathroom, and then install the drain pipe. The drain nozzle should be with.

2.Sinking layer leveling. Subsequently, we leveled a slope according to the lowest point of the installed drainage pipe opening, with the aim of allowing water to accumulate.

3.The sunken layer is brushed waterproof. After the leveling is done, brush it twice to make it waterproof.

4.Pipes are routed and overhead partitions are made. When making partitions, of course, you need to consider the location of the pipes.

5.Backfill, cloth rebar, make concrete. If it is necessary to do backfilling, it is generally used to backfill ceramsite, and of course there are many families.

The waterproof layer of the bathroom refers to the original ground, and the secondary drainage is the original drainage position or the floor drain is not suitable for your use, you need to re-set the new drainage position, the practice is to use PVC or PPR pipe to connect to the existing floor drain at the position you need.

The secondary drainage of the toilet is a design method to prevent the leakage of the water pipe or the floor at the bottom of the toilet from leaking. After all, there will be leakage or sediment accumulation in the bathroom when water is used for a long time, and the soaking of cement for a long time will more or less penetrate into the downstairs, so that secondary drainage can solve this problem well.

<>1. Install the drainage pipe: install the drainage pipe after the hole is opened in the main drainage pipe of the bathroom, and pay attention to the nozzle before the drainage pipe loss should be the same height as the waterproof layer of the original sinking layer. Second, the subsidence treatment:

Make a slope according to the leveling of the drainage pipe mouth. After that, brush the waterproof paint twice. Third, the pipe, the maker imitates the partition:

When making partitions, the location of the pipes laid should be fully considered. Fourth, use ceramsite with good drainage for backfilling, and then lay steel bars for concrete treatment. Fifth, the finishing work:

In the bathroom, the floor is clear, and the surface is brushed twice and waterproofed, and then the plain cement slurry is treated.

The bathroom is an important area in the decoration, special attention should be paid to the details during construction, and waterproof work should be done, otherwise it is easy to leak water, which not only affects the relationship between neighbors, but also needs to be reworked, which is more troublesome. So how to do secondary drainage in the bathroom? What are the precautions for bathroom decoration?

1. First dig a hole in the main drainage pipe and install the pipe. Note that the height of the nozzle should be the same as the original waterproofing layer, and the other end should be connected to the drainage main. In addition, the openings should be polished smooth, without burrs, and the part connecting the main pipe should not be more than three millimeters above the pipe wall.

Then, the newly installed drainage pipe mouth is used as the lowest point, leveled, and a slope is made, the purpose of which is to allow the stagnant water to be smoothly discharged into the secondary drainage pipe.

2. Next, paint waterproof, pay attention to apply more than twice. Next, the piping is arranged and the overhead partition is designed. If you need to backfill, you can use ceramsite, and there are many owners who directly do overhead without backfilling.

The next step is to apply waterproofing twice, then protect with plain cement slurry, and finally perform a closed water test.

What are the precautions for bathroom decoration.

1. In order not to affect other spaces, it is best to design a large area of windows, so that the water vapor can be discharged in time. If you can't open the windows, you can install ventilation equipment such as exhaust fans, which can also speed up the air circulation.

2. The materials selected should be safe and reliable, and the endless mausoleum should be greedy for low price and choose some inferior products, such as the ceiling needs to be moisture-proof and waterproof. The switches and sockets in this area are also of high quality, preferably with a cover to avoid short circuits and electric shocks.

Article summary: The above is the relevant content of how to do the secondary drainage of the bathroom and what are the precautions for bathroom decoration, I hope it can help some friends in need.
