انی The correct plumbing steps of the building
🔸 The first step in building plumbing is to prepare an engineered plan and then implement it accurately and correctly, but the next steps depend to a large extent on the type of pipe used. And it continues on the higher floors until it ends.
🔸 After completing the plumbing of each unit, they cover the main pipes with caps and repeat the same work for the units of the other floors, and at the end of the work, the pipes of the units are connected to each other with the help of fittings. Basically, this work is accompanied by aeration so that the water flows completely in the pipes.
🔸 At the end, another test is done to make sure that the work is correct.
All these steps must be done with full precision and the connections between the pipes should be as delicate as possible so that the building's plumbing system is efficient for the residents in the long run.
انی The principles of plumbing in the building 🔶
🔸Care of the piping system against sunlight: According to the building plumbing standard, polymer pipes should not be exposed to direct sunlight, so if piping is being done in open places, these pipes should be protected from sunlight using an insulating cover, otherwise the pipes will be damaged and may even be destroyed. be buried It is mandatory to take care of the pipes that are not covered in materials against freezing or bursting, so salt water with a certain concentration should be used after the implementation of the piping system of the building to perform relevant tests, so that if water remains in parts of the pipe, the possibility of freezing will decrease. Of course, this salt water will be removed from the system when the equipment is installed. Insulating the pipes with suitable materials is also a good solution to prevent possible damage from the cold.
🔸 Pipe placement depth: When placing the pipes in the ground, it should be noted that the piping should not be too shallow or too deep. If the pipe is placed on the surface in a normal pit, it will require high care and we may even see the ground subsidence when heavy vehicles pass over it, which is considered a serious damage. On the other hand, placing the pipe at a great depth is not suitable because it will be damaged by soil pressure, and in this case it will be difficult to repair it.
🔸 Attention to the rate of water speed: Another important point about the plumbing of the building, which is very important, is the rate of water speed. If the water flow rate in this system is not adjusted, i.e. it is too high or too low, a lot of water will be wasted and the building's water equipment may not work properly. To reduce the effect of ram impact in piping, the water flow speed should be controlled, but the reduction of the water flow speed in the pipes should be to such an extent that the increase in the diameter of the pipes does not increase the costs. But the factors affecting the water speed are: Pipe size: There is a direct relationship between the water flow speed and the pipe size, that is, the smaller the size of the incoming water pipe, the lower the water speed. Water temperature: Like the pipe size, the same relationship exists here. For example, the higher the water temperature, the higher the water speed, but to prevent corrosion of pipes and save energy, it is better that the water temperature is not more than 60 degrees Celsius. Water pressure: Unlike the size of the pipe and the water temperature, the relationship between the pressure and the speed of the water flow is not a direct relationship, and as the water pressure increases instead of increasing the speed, we will see its decrease. does.
🔸 Taking care of the plumbing system against construction materials: Considering that when the plumbing of the building is done, other parts of the building are also involved in construction operations, there is a possibility of damage to the plumbing system, but this can be prevented by observing a few points: ▪️ Pipes should not be placed directly on the floor of the building that is being built, and it is recommended that cardboard or cardboard be placed under them to protect against any damage.
The plumbing system of the building used various methods that we will introduce at the end of this article:
- Installation of a double one-way valve with a drain valve
- Installation of a safety valve for the pressure difference between two one-way valves
- Installation of a pressure vacuum breaker
Of course, it should be noted that the equipment that is used to prevent the return of water flow due to reverse pressure, must have be standard Also, the one-way valve that is installed to prevent the return of water flow into the pipe, must be spring-loaded type with a watertight seat. The installation of a vacuum breaker alone is not enough to prevent the return of the flow.
