Is the abnormal water supply of the house a quality problem?

The following are housing quality problems:

1. The building is unstable. It is manifested as sinking after the settlement period; Uneven settlement causes the building to tilt; The overall strength is insufficient, and the building is shaken or swayed in strong winds; Due to the imperfect structure, the load of part or all of the load-bearing system is insufficient, resulting in the hidden danger of partial or total collapse of the building.

2. Cracks. This includes cracks in walls and floor slabs. Cracks are divided into strength cracks, settlement cracks, temperature cracks, and deformation cracks, which are caused by insufficient material strength, uneven stress on structures and walls, insufficient tensile and extrusion strength, uneven settlement of buildings, quality of building materials, and insufficient drying after masonry.

3. Leakage. Due to the imperfect waterproofing process and the poor quality of the waterproof material, the roof leakage, the horizontal leakage of the kitchen and bathroom outward, and the vertical leakage downstairs, the vertical leakage is mostly seen in the joints of various pipelines and floor slabs. In the rainy season and when the water consumption of the kitchen and bathroom is large, the leakage will seriously affect the normal life of the user, destroy the ground decoration, and affect the relationship between the upstairs and downstairs neighbors.

4. The wall is empty and the wall skin falls off. The connection between the blocks and layers inside the wall is not good, and a hollow is formed under the action of pressure and temperature difference, which reduces the overall compressive capacity of the wall and makes the surface stucco layer easy to fall off. Sometimes, in the case of no hollow drum, due to the quality of the stucco material on the surface of the wall, the stucco process does not meet the requirements, and it will also cause a large area of wall skin to fall off.

5. Poor sound insulation and heat insulation. The sound insulation and shock absorption effect of the partition wall and floor slab between households and between halls and rooms in residential buildings are not good, and they cannot meet the requirements of privacy; The roof and exterior walls cool down quickly in winter and heat up quickly in summer, which cannot meet the requirements of thermal insulation and insulation. The reason for the above phenomenon is that the thickness of the sound insulation and thermal insulation materials of the wall and roof is not enough, the quality of the materials is substandard, or the construction technology does not meet the requirements.

6. Poor airtightness and deformation of doors and windows. Some doors and windows have been installed since the beginning, and some have the problem of poor sealing, part of the material or overall deformation after a period of use, and the serious ones cannot be separated from the line of sight, the effect of blocking the wind and rain, and some cannot be closed and opened. The reasons for the above problems are the poor quality of the materials selected, the lack of dryness of the wood or the invasion of moisture after installation, and the workmanship is rough.

The quality problems of doors and windows are generally not harmful, and only local repairs or replacements are required. 7. The upper and lower water runs and drips. The reason for the occurrence of the phenomenon of running and dripping is that the horizontal and vertical design of the water supply and water pipelines is not reasonable enough, and the quality of faucets and toilets is not up to standard.

8. The design position of water, electricity, heating and gas is unreasonable. Including pools, bathtubs, squatting (sitting) toilets, water meters, floor drains, power switches, power sockets, electricity meters, radiators, gas stoves, gas meters and other design types are not perfect, and the design location does not meet the requirements of daily life, affecting the furniture layout. Some electrical equipment even has leakage and fire hazards.

9. The design of public facilities is unreasonable and the quality is not up to standard. For example, the location of the stairwell is inconvenient, the width of the staircase is too small, the operation quality of the elevator is unstable, the public lighting facilities are not perfect, and the fire safety facilities are lacking.
