1. Mix cold and hot water pipes
white is the cold water pipe, red is the hot water pipe, mix and connect the cold water pipe and the hot water pipe
there are hidden dangers: the expansion rate of cold and hot water pipes is different. Due to thermal expansion and cold contraction, the cold water pipes break and leak
standard operation: distinguish hot and cold water pipes by color and operate strictly
2. Use glue
standard operation: at present, there is no pure natural and pollution-free glue on the market, and the substitute is 108 glue. But we must identify better brands
3. The wires are not covered with insulating tubes
during construction, the wires are directly buried in the wall, the wires are not covered with insulating tubes, and the wire joints are directly exposed
there are hidden dangers: This is very unsafe. After check-in, wires may be damaged and short circuited due to some reasons, such as aging wires; At the same time, once the wire is broken, there is no way to change the wire at all, only smashing the wall and knocking the ground
standard operation: the wires must be laid with insulating sleeves on the outside. At the same time, the circuit connectors should not be exposed outside. They should be installed in the wiring box, and no joints are allowed between the junction boxes
4. Dismantle and change the waterway at will
mislead the owner to dismantle and change the waterway at will and waste money when the owner does not understand the decoration
there are hidden dangers: wasting money is only one aspect. Once the waterway is not sealed or the pressure test is not carried out, the water pipe will burst
standard operation: move when the pipeline should be changed, and firmly do not move when it should not be moved
5. Strong and weak electricity are placed together
typical Jerry building. Strong electricity? Such as lighting wires? And weak current? Such as telephone line and network line? Put it in a tube or box, and lay one less tube, Save time and effort (bathroom dynamics.
there are hidden dangers: there will be interference when making phone calls and surfing the Internet. At the same time, there is a risk of fire if there are too many wires in one pipe.
standard operation: strong and weak electricity should be wired separately. It is strictly forbidden for strong and weak electricity to share a pipe and a bottom box.
6. There are no connecting accessories if the length is not enough.
because the length of the insulating pipe is not enough, this is just a turn, and there is no connecting accessories, and a section is exposed at the junction with the junction box.
Hidden danger: electric leakage may be caused by aging lines after a long stay
standard operation: there should be something connected between the nozzle and the junction box
7. Repeated wiring
a large number of repeated wiring and multi-purpose materials waste the financial and material resources of the owner
hidden danger: once there is a problem with the line, if “ A snare ” It is difficult to detect in the layout of
standard operation: carefully arranged. Under the condition of not exceeding 40% of the capacity of the pipe, the line of the same direction can be threaded in one pipe. However, strong and weak electricity must be separated
8. The line pipe is damaged by subsequent works
typical brutal construction. After the pipeline was laid, it was slotted on the ground, and as a result, the laid pipeline was penetrated
there are hidden dangers: after checking in, you may find that there is no electricity in a room at home, so you can only check all wires at home one by one and re thread them
standard operation: construction cannot be carried out again at the place where the pipeline is laid
if it is damaged, it is strictly forbidden to connect halfway when changing wires. When the circuit load is large, the joints of wires in the threading pipe are easy to spark and cause fire
