Building Sewage Plumbing

Sewage plumbing is one of the most important and most used parts of any building. Therefore, the tips and rules of plumbing must be followed properly when performing sewer plumbing.

Some Important Tips on Building Sewage Plumbing

Horizontal sewer pipes should be fitted with a slope and a uniform. The slope over the pipes increases the flow rate of the sewage, resulting in the discharge of sewage water and the solids and wastes remaining in the pipes, resulting in pipes clogging and requiring pipe opening and pipe clogging. Low slope also reduces or even disrupts the flow of sewage, resulting in clogged pipes. The amount of sewage piping slope is 1 to 5 percent. The most appropriate type of sewage and the length of the slope between the two slopes in the sewer piping of buildings is 2%.

  • Use 45-degree fittings in building sewer piping.
  • Sewer pipes should be restrained by pipe fasteners.

Direct piping is a priority in sewage piping

Sewer pipes should be installed as straight as possible and not pass through the building. If the sewer pipe passes through the building, it should be covered with at least 15 cm of plain concrete, and if the pipes are within one meter of the foundation and walls, it should be covered with concrete to the subsurface.

Install the sewer inspection valve before connecting the vertical sewer pipe to the horizontal sewer pipe. At the bottom of the horizontal sewer pipes, it is also necessary to install a check valve. The location of the checkpoint should be accessible to people.Some Important Tips on Building Sewage Plumbing

Tips after Running the Sewage Plumbing

After running the sewer plumbing of the building to test for leakage. we must test the plumbing circuit. The test can be done with water, compressed air, and smoke. the most common way to use water. The way to do this is to close all openings through the sewer hose and insert the water into the sewer pipes to completely fill the water.

  • Carefully inspect the joints and fix them if there is a leak and repeat the test.
  • If the building is high, test the pipes in several steps, as the pressure of the test water column on the lower floors will increase.
  • We experiment with these buildings part by part. That is, the testing of each class is performed separately.


A well-equipped building sewer system consists of the following parts:

Building Sewage Plumbing Unlike building water plumbing, there are many parts that failing to install each section that can cause problems for the entire sewer system.

Wastewater pipe:

The sewage pipe in the sewage system, as its name implies, has the task of directing waste to the well outside the building.

The design of the pipe is mounted up and down in buildings, due to the fact that the earth’s gravitational force has come from sewage pipes to make it more useful for faster sewage transport.

Vent or vent pipes:Some Important Tips on Building Sewage Plumbing

These pipes are primarily used for ventilation alongside sewer pipes in the building and their second function is to assist in the discharge and movement of sewage by generating currents and air pressure in the sewer pipes.

The shape of the ventilation pipe is located along with the building and, unlike the riser sewer pipes, the vent pipes are mounted upward. The main cause of poor ventilation in the sewer system is mainly due to the incorrect installation of vent pipes.


Siphon is also an integral part of the sewage system. It is necessary to use a siphon under the sink, in the bathroom and toilet to prevent drainage of the water pipe.

Because of the shape of the bottoms, siphons always hold some water to prevent the drainage pipe from drying out. The benefit is that unpleasant insects and odors can no longer enter the building.

After you get acquainted with the components of the sewer system in the building, it is time to consider the sewage systems in the building. To find out the best sewage system in the building, we must first consider the most common ways of implementing sewage in the building.

Types of sewage piping in buildings can be divided into two categories:

Traditional sewage and sub-ceiling sewage

Some Important Tips on Building Sewage PlumbingIndoor wastewater plumbing can be implemented using both cast iron, porphyry, and polycarbonate pipes in both ways.

However, the use of cast iron pipes in sub-ceiling plumbing is very sensitive and pipes should be properly restrained. Therefore, polychaetes and porphyry pipes are often used in sewage piping today. . Click here to read the article on Fit Piping.

Traditionally building sewer piping:

In this method of sewage piping, the pipes are placed in the building as a floor. This is called traditional sewer piping because the old way of sewage piping in the building has been this way.

In this way, after connecting the ventilation pipes and siphons to the sewage pipe, they cover the floor of the building under construction or remodeled under materials such as cement.

As an example, we can refer to one of the projects carried out by a team of specialists in the 24-hour facility for the implementation of bed sewage piping. Click here for a full review of the project steps.

Some Important Tips on Building Sewage PlumbingIn this project, in Amirabad street and in the municipal office building, sewage pipes have been used in this system by using pipes, like bedrooms, and in order to ventilate the sewage pipes from the ventilation pipes in the services. Sanitary used.

Building a sewage pipeline in the following way:

Sewage plumbing in the building is as follows that the pipes pass under the roof instead of lying on the floor.

In fact, the only difference between the traditional and under-roof plumbing is how they are placed in the building.

In one of the projects carried out by our partners, our specialists have plumbed the subterranean sewage in the residential complex.

the ground floor sewer is plastered as floor and the next floor sewer is subjected to hybrid roofing using cast iron and porphyry pipes.

Implementation of sewage plumbing by bed method

Factors that indicate a proper sewer plumbing in the building can be considered in areas such as the speed of wastewater movement, non-emission of sewage odors, easy access to the pipes in times of emergency and pipe life.

In what ways is the sewage piping less harmful to the sewer pipes?

As mentioned in the brief description above, pipes pass below the ceiling in the pipeline and as a result, no pressure is put on the pipes through the materials or heavy materials used in the building. But in traditional plumbing, pipes are directly in contact with the floor and the center of gravity of the building, and breakage and damage to sewage pipes in this manner is inevitable. Refer to the article on Sewer Pipe Repair’s article to learn how these pipes are repaired.

In which method of wastewater piping is the rate of movement of sewage material within the pipes higher?

answer to this question: it can be said that sewage piping does not play a significant role in the rate of wastewater movement in the floor or under-roof models.

In general, other conditions such as proper slope in the pipes, how the pipe is welded, and the material of the inner surface of the pipe determines the rate of sewage movement within the pipes. In some buildings due to the use of poor quality pipes and on the other hand due to non-compliance with the standard slope in the pipes, sewage material accumulates in the pipes and at the joints, causing sediment and odor.

Which method is more cost-effective than sewer plumbing in a building?

The cost of running a subterranean sewer pipeline is due to the need to use high-quality pipes. the use of skilled and expert plumbing. the hard work as well as the necessity of ducting between the walls of the building to cross the sewer pipes far higher than traditional piping. Or sleeping.Some Important Tips on Building Sewage Plumbing

Which method of execution is faster than Sewage Plumbing and piping?

Generally speaking, in-floor plumbing, the speed of plumbing performance is also increased because there is no need to scrutinize the engineering of the building, install ducts and also connect the pipes under the roof. But the sewer piping speed in the under-roof model can also be increased to a high degree by the use of porous pipes.

In which way is it easier to access pipes than Sewage Plumbing in a building?

  • The biggest advantage of using a sanitary sewer in the building is that you can easily access pipes at any time, such as repairing, splitting or replacing sewage pipes.
  • Imagine sewage pipes lying on the floor of the building due to material pressures, frost, or any cause of bursting or leakage and need to be repaired. In this case, the amount of damage and repair costs of the pipes will be considerable.
  • But if the sewer system in your building is under-roofed, your costs will be halved. Because the pipes are close to you and accessible, you can start the process of removing the pipes by removing the hemp or false ceiling.
  • However, as we said, you will have fewer problems with pipe bursts and frosts due to the use of high-quality pipes and the lack of pipes on the floor. Click here to find out how to fix, break, or burn out old building pipes.
  • You may even want to add a new toilet or a new bathroom for your building. If the former sewer pipes in your building are bedridden, it is very difficult to split and install sewage for the new bathroom or toilet. will be.
  • While, as mentioned above, one of the advantages of sub-ceiling plumbing to floor plumbing is the possibility of getting new splits to the sewer pipes without the downtime and high time and cost.
  • So the possibility of running sub-plumbing in a residential building is another advantage of using this method.


Conclusion  for Sewage Plumbing:

It can be concluded that the type of building is a crucial factor in choosing the best type of sewage in the building and the type of sewage in different buildings can vary.

So it’s up to you to choose the best type of sewer for your building based on the type of building.

But keep in mind that always the best piping in the building gives you the guarantee that there will be no need to spend many years again and this will only happen when you have experienced and experienced people. Use the plumbing of your building
