In addition, you should pay attention to the engineering quality of hydropower. Now introduce several inspection methods and construction standards. First look at the wire construction method:
1. Whether electrical products are qualified products that meet relevant standards.
2, the use of fire-retardant dark pipe laying, wire should not have knots and kinks in the pipe.
3. It is forbidden to directly bury the wires in the plaster layer.
4, "Fire line into the switch, the zero line into the lamp", socket wiring should meet the "left zero right fire ground on the" provisions.
5, air conditioning and high-power electrical appliances should be set up separately (flame-retardant tube processing).
6, power lines, television lines, telephone lines must not be installed in the same pipeline.
7. The switches and sockets are firmly installed and the position is correct. The cover plate is upright, close to the wall, and there is no gap around.
After the installation of electrical engineering, electrical power should be provided, lighting test light, switch control and so on. After the completion of the project, the customer shall be provided with wiring drawings showing the wire specifications and directions.
Second, the installation of the pipeline should:
1. The pipelines are arranged reasonably, laid firmly, horizontally and vertically, and the switches and valves are installed neatly, which is flexible and convenient to use.
2. The water supply pipe and its accessories are tightly connected. There is no leakage in the water pressure test, the water flow is smooth, and the water meter operates normally.
3, the drainage pipeline should be unblocked, no obstruction, no leakage, the bottom of the bathtub should be higher than the drain bend, and the floor drain dice should be slightly lower than the ground.
4, sanitary ware is firmly installed, the appearance of smooth and clean.
Hydropower renovation
In all decoration projects, hydropower engineering is crucial, and at the time of the budget, all company quotes do not include hydropower project costs. However, in the actual operation, the actual amount of work is calculated, so some customers do not understand the quotations, free to change the water and electricity, to the settlement fee, before ... 80 after the small husband and wife marriage The mood of the room is reflected in the fashion.

However, in the actual operation, the actual amount of work is calculated, so some customers do not understand the quotations, arbitrarily dismantled and changed hydropower, to the settlement fee, only to find a far cry from their imagination, leading to The dispute between the two parties caused a deadlock in the relationship and it is difficult to continue the work behind. Therefore, in the hydropower reform project, the goal should be clear, and the original pipelines should be kept intact, and they should be changed according to the designer's design. This way, you also have a good idea.
