Steps to implement extensions of sewer and plumbing

Steps to implement extensions of sewer and plumbing

At the present time does not vacate the house work sewage and plumbing work , and it is the implementation of these actions during the process of building a house , and the selection good material for the execution of the sewage and plumbing, so as not to play in the future work of the repair may be charged more at the same time annoying.

Provide drainage extensions are extensions that are used to get rid of the water used , whether in the room or rain water services , health protection and comfort to users of the building and there are two types of sanitation:

1. Sewer extensions

2. Extensions of rainwater drainage

First: the sewer extensions

And sewage extensions are extensions discharge of liquid and solid waste services rooms . We will look explanation to the implementation steps , namely :

The first step : the work of slots for Sewer lines

And begin steps to implement the sewerage network to extend this network under the ground floor . Or be extended through this layer in this case drain pipes are placed in the ground before pouring the concrete , so as to leave a place for the passage of sewer pipe through the ground and without having to cracking .

The second step : the implementation of the internal drainage network

Is implemented internal sewage network in conjunction with the first step. The different pipe diameters used sewage network depending on the size of the building , and often start small buildings of 2 -inch diameter pipe , used to connect between health kits ( laundries , foot basins and bathtubs ) and floor drain . The connections are made between the sink in the ground floor of a bathroom or kitchen and sewer outside the building with a 4 – inch diameter pipe that this tube is provided with a ventilation pipe extends from the point they met to the roof of the building up of at least one and a half meters . And ventilation tube is used to eliminate odors in the sewerage network .

The third step: the implementation of the sewerage network outside the building

After the completion of the internal drainage network is linked to foreign exchange and network that combines all internal drainage lines and have a diameter of at least 4 inches thick and high . And Preference must be done to exchange lines to start the drainage network of the top point at least to the point and be piped your tendencies at least 2 cm per meter . The pipes are wrapped after controlling tendencies reinforced concrete to protect the tubes from breakage. The pipe is connected to a network used by the foreign exchange connected to public sewer network using either the inspection chambers or using the wiring holes . We will look explanation of each .

1. Manholes

Manholes is one of the traditional methods , which consist of a major inspection and inspection chambers and sub ​​- communicate with each other tube with a diameter of at least 4 inches . No less measure manholes 1x1x1 m . And take into account when using this type of drainage systems and choose the kind of high-quality manhole covers . Poured reinforced concrete ceiling , taking into account that the cement used in the concrete of the type and sulfate – resistant walls are thick manholes high. This is done for manholes surveyor from the inside with a thickness of not less than 20 mm using sulfate – resistant cement and sealing material Nominated taking into account the work of the insulator manholes from home and abroad .

Wiring slots

Slots and wiring are newer method is to use the hidden network ( the U.S. system ) , which are replacing manholes sub wiring holes provided to the line when changing direction and in straight lines . And this should provide a good ventilation system .

Step Four : Test sewer extensions

Are tested sewage pipes by installing a tube up one and a half meters at the highest point of the drainage network and the closure of this network by linking with the inspection chambers or openings wiring network is filled with water to determine the level of water in the pipe that has been installed . And left for two hours to make sure there are no water leaks .

Note

In the case of a basement in the building lift pump is installed to install tank manhole basement and reached the pump to the main drainage network . This pump is working when it reaches the water level inside the manhole to the high level of float automatically and begin the expulsion of manholes through expulsion caller line the main drainage network and the pump continue to work until it reaches the level of Blackjack to the low status will depend pump automatically

II : Extensions discharge of rainwater

And rainwater drainage network used for rainwater drainage surfaces and open spaces of the building. And be a floor sink connected to 4 – inch diameter pipes pass through the outer walls of the building and ending before the ground level . Where rainwater is discharged along the building and is not linked rain drainage network on the external drainage of the building and the presence of a private network discharge of rainwater in the streets near the building, so as not to cause a rash of streams .

Are tested rain water drainage pipes through closed from the bottom and fill with water to determine the level of water in the tube and left for two hours to make sure there are no water leaks .

And shall upon receipt of the implementation of the exchange extensions

1. Make sure pipe diameters used and the thickness and matching extensions to the approved scheme .

2. Be careful not to store sewage pipes under direct sunlight .

3. Make sure your tendencies extensions .

4. Make sure there is ventilation holes and slots wiring .

5. Make sure pipe coating after controlling tendencies reinforced concrete .

6. Make sure the quality of the materials used in the extensions.

7. Ascertain the number and the safety of the installation of rainwater drainage holes on the surface and detected on the exchange manholes rain.

8. To ensure smooth flow of wastewater inspection rooms open lids and detection .

9. Make sure there are no water leaks .
