Kitchen drain pipe: those who can use floor drain can find a way to make floor drain.
Some are local materials, which are cheap or even free.
Attention to construction details a.
In order to prevent water return, it is suggested to increase the drainage pipe path when arranging the balcony drainage pipe, do not make 90 ° right angle, and try to make oblique drainage to form the shape of Y-type drainage.
B.
Not all the sewage will be discharged directly downstream.
B.
all joints are physical construction and glued connection.
The drainage speed of the floor drain is far less than that of the shower.
During the water test, some blockage is not easy to be found, and the blockage problem does not appear until it is put into use.
Toilet drainage pipe A.
E.
Stone or ceramic tiles or other materials can be used for capping to achieve protection.
2.
In the past, the diameter of this shower floor drain was generally selected Φ 50 drainage pipe, but in the later life and use process, when we shower, a large amount of water flows to the ground.
C.
It is best to have an independent trap for each branch sewage pipe, so that the diversion sewage will not affect the drainage speed, but also avoid the phenomenon of odor, drainage retention and floor drain overflow; In order to prevent the water from leaking downstairs, in addition to being waterproof, we can also take preventive measures for the drainage of concealed floor drain.
After the drainage pipe is completed, the special submerged bend must be fixed with red brick or cement.
Remember, try not to use 90 ° elbow.
There is no 45 ° elbows, 45 ° inclined tees, concealed leakage, etc., which is easy to cause water splashing when the sewage is impacted and pour back into all the pipes around.
Foreign matters such as wood strips, stone slag, garbage or mortar fall from the vent pipe orifice or inspection port of the roof, resulting in pipe blockage.
B.
The blocked part shall be found out in time and the sundries shall be cleaned up…
If there is no squatting pan in our shower area for drainage, a floor drain will be left for drainage.
Therefore, after the installation of sewer pipe and before concealed burial, irrigation test must be done! If the drainage flow rate is found to be slow during the drainage process, it indicates that there is foreign matter blockage in the horizontal branch pipe.

stepped drainage pipe: the pipe diameter is determined by Φ 110→ Φ 75→ Φ The best way to prevent the change of sewage backflow is to use the drainage pipe with the diameter of 50, but it is the best way to prevent the change of sewage backflow Φ 110 pipe, preferably close to the main drainage pipe.
Therefore, if we can replace 50 pipe with 75 pipe, increase the drainage pipe diameter and expand the drainage outlet, the ponding problem may be well alleviated.
Shower floor drain is also recommended by Φ Replace 50 with a larger pipe diameter Φ 75.
The water volume is fast and large, which is bound to easily cause ponding at the floor drain.
The method of balcony drainage pipe is a and Y-type: the sinking height of the balcony is not enough to make ladder drainage and trap.
Use red bricks for peripheral protection.
They can be backfilled directly with on-site construction slag, and they can also be backfilled with ceramsite, carbon slag and other methods.
There are many ways to protect drainage pipes, such as cast-in-situ non backfilling protection, red brick + stone protection; There are also many backfill materials.
Right angle method: adopt the shortest and most material-saving path for drainage pipe layout, and adopt 90 ° elbow.
The periphery of the drainage pipe must be cleaned with paper towels or wet pads before construction.
Ordinary drainage pipe: diameter Φ 110 tube directly into Φ 50 pipes, 90 ° elbows and positive tees are used, which will share traps and other methods.
We often find that there are problems such as odor and poor water flow in the toilet, which may be caused by improper drainage pipe practices.
(construction slag backfilling) (ceramsite backfilling and cast-in-situ sealing backfilling, the disadvantage is that once maintenance occurs, the maintenance cost is very high) (carbon slag backfilling) reminder: the irrigation test of drainage pipe is very important! During the cross construction of civil engineering and installation, although the pipe orifice will be temporarily blocked, it will often be opened manually.
When the water leaks into the waterproof layer, we drain the water to the location of concealed floor drain through artificial drainage, so that the leaked water can be discharged from the concealed floor drain instead of continuing to seep through the backfill layer downstairs; In the process of installing the drainage pipe, in order not to cause sewage congestion and sewage backflow, we can use 45 ° elbow, 45 ° inclined tee and other pipe fittings to lay the sewage direction.

Because there are residues and leftovers for a long time, try to use the diameter as much as possible Φ 75 drainage pipe.
Key points of drainage pipe construction 1.
This method, especially when there is washing machine drainage on the balcony, if it is not handled well, it is particularly easy to produce water return in the later stage.
