Water supply and drainage includes water and drainage facilities in toilets and kitchens. Generally speaking, in the process of decoration, the equipment in the kitchen and bathroom will often be displaced and replaced. When replacing the water supply pipe during construction, attention should be paid to setting the water meter in a place that is easy to see and maintain, and placing it horizontally. The valve is preferably made of copper cut-off valve. When installing, attention should be paid to the reliability of pipeline installation and fixation, and the thickness of decorative surface should be considered, so that the clear distance between pipeline and wall should be controlled at about 20mm to facilitate the maintenance and disassembly of pipeline in the future, and the water supply pipeline should not be buried in the dark. The consequence is that it is difficult to maintain and the decorative surface must be destroyed. When the water supply pipeline passes through the hall, room or hanging cabinet, a dewproof layer should be added, and the hot water pipe should be insulated.
2. Electricity-related
The original line design should be considered in the electrical transformation, and the lighting, sockets and air conditioners should be controlled by shunt as far as possible. At the same time, the load of each line should be distributed reasonably, and professional electricians must be invited to carry out the construction, because the personal safety problem can not be ignored.
Most of the pipelines are buried underground, and the pipes are mainly PVC pipes and steel pipes. Matching accessories and boxes must be used when piping. PVC pipes should have smoldering resistance and impact resistance. The thickness of the box should be greater than 2.5mm, the pipe connection should be inserted, and the joint surface of the joint should be brushed with special glue; Metal pipes should be connected by thread or welding, and jumper grounding should meet the requirements. The clear distance between the buried pipeline and the wall surface should be greater than 15mm, otherwise the surface layer is easy to crack, so it is strictly forbidden to make transverse nicks on the wall, otherwise the wall strength will be affected; The switch box shall be set at 1.4m from the ground, the socket box shall be not less than 300mm from the ground, the outer opening of the box shall be flush with the wall, and the cover plate shall be straight and tight.
3. Natural gas and natural gas
From the perspective of safety, the gas company must be asked to transform the gas and natural gas pipelines before gas testing can be used. U-shaped pipe is used in the gas pressure test in the test, and it is not easy to smear the test on the pipe joint with soapy water. Please pay attention. Gas meters and pipelines cannot be installed in a concealed way, otherwise it is inconvenient to check and it is not easy to find pipeline leakage.
The water heater must not be installed in the bathroom. The forced exhaust water heater should connect the exhaust pipe to the outside. The forced exhaust water heater should be installed in a ventilated place, and the exhaust ventilation should be strengthened when it is used.
4. Air conditioning
Most users choose wall-mounted split air conditioner, and the model and cooling capacity should correspond to the indoor area, which can be selected according to the comparison table provided by Shi Jia, in which cooling capacity and noise are two main performance indicators, which can be considered more. The outdoor unit should be installed in a well-ventilated place, with firm installation, regular cleaning, smooth discharge of condensed water and tight heat preservation of pipelines.
5. Water heating
The renovation of water heating system should be carried out by professional construction personnel, and the indoor riser should not be changed, so as not to affect the use of the whole system. You can change the direction of the branch pipe and the position of the radiator. After reconstruction, water pressure test must be carried out to verify its tightness. In addition, the water test before the heating season must pay more attention to observe whether there is leakage.
In a word, because the hydropower strength of home decoration team is generally not very strong and formal, users can choose a good construction team according to the above professional points when installing hydropower to supervise the construction process and reduce the occurrence of hidden dangers. I hope the above suggestions can help you live a satisfactory and comfortable life.
