In home improvement, hidden projects mainly include the laying of water and electricity pipes, floor bases, baseboards for protecting walls, base layers for doors and windows, and ceilings. Due to the special concealment of the hidden project, it is easy to cut corners in the decoration and it is not visible on the surface. According to reports, the problem with hidden projects is mainly due to the irregular construction of the decoration team and the omission of some seemingly insignificant and actually very important steps. Many consumers do not have the time to look at the scene, or although they are on the spot but do not know anything about it, they cannot find the problem. Experts from Ningxia Interior Decoration Supervision and Inspection Station provided consumers with an in-depth analysis of the hidden works in the home improvement, and put forward special attention.
Air reform
In home renovations, heating and gas are "untouchable" by the decoration company. Heating and gas reforming is very strict with respect to safety requirements. Normally, it must be operated by professionals to ensure that there is no leakage or leakage of gas. Be careful not to wrap the gas pipes during the renovation.
Circuit modification
Electrical wiring is spread throughout the room and safety is especially important. A good circuit renovation program should not only pay attention to external effects, but also take into account safety factors and the convenience of future maintenance. In actual construction, it is also necessary to adjust the circuit capacity and deal with the interference between strong and weak electricity. From the perspective of safety and maintenance, the power cord should also be fitted with a PVC pipe, and elbows should be used at the joints. If the live line can be handled better. When laying the circuit, the wires must be color-separated and need to be threaded. Do not bury the wires directly on the ground or wall. This will leave security risks. After the electric line is laid, the length of the stay line in each line box does not exceed 20 cm, and the length of the lamp line is determined according to the height of the ceiling, generally more than 10 cm above the ceiling.
When the circuit is reformed and accepted, it is first necessary to ensure that the wire conduit is unblocked. Second, you can use the electric pen to check the socket order. It must be the left zero line, the right fire line, and the upper line. Also use the electric pen to check the switch wire sequence. The switch must control the fire wire. At the same time, use the insulation resistance meter to check the insulation resistance value of each circuit is not less than 0.5 megohm. After the acceptance inspection, pay attention to save the circuit construction drawings, because the drawings are the reference for future maintenance.
