There is a lot of knowledge in hydropower engineering, and inexperienced decorators can’t figure it out after looking at the countless knowledge articles on the Internet. Therefore, we have recorded the real process of the water and electricity rectification of Mr. Li’s home for everyone, so that everyone can learn some water and electricity knowledge that they usually cannot understand during these actual operations.
Address: Wuwei East Road
Community name: Hengsheng Dingchenghua Mansion
Construction stage: Water and electricity project
Acceptance time: 45 minutes
Length of rectification: 3 hours
Community environment
The first thing you see when entering the community is the "golden" stone, the vibrant morning light and the golden fonts complement each other. Cheng Hui. The fresh air in the community makes me feel refreshed. I can reach the building where netizens live just by passing the "mountain" and "water". The ancients said that those who live in Leshan are benevolent and those who enjoy water are wise. In a community like this, there must be both wisdom and benevolence.
Then there is the "mountain" of the "benevolent" person. There are mountains in the water, rocks in the mountains, and wealth in the rocks. Fengshui, mountains and rocks, the wealth is rolling in!
Entrance to the owner’s building
Understand the situation before acceptance
Various construction drawings are very important. The construction personnel will carry out construction based on these drawings. We check We obtained the construction schedule, construction renovation drawings, circuit diagrams, waterway diagrams, switch and socket diagrams, etc. of Mr. Li’s construction site. Judging from these drawings, the water and electricity drawings of the ID urban space are relatively in place. The construction workers have drawings to follow, and the supervisors also have drawings to check. So before acceptance, let’s first understand each situation!
Construction time
Taking the elevator all the way to the site, I found that the construction workers of the decoration company were already cleaning inside. I learned about the preliminary situation of the decoration with the construction team leader Ding, and checked the water and electricity wiring. At this time, the owner Mr. Li arrived. After communicating with him, I learned that the decoration of their home will start on October 23, and the contract stipulates that it will be until January. After completion, the water and electricity were completed in just one week, which was very efficient.
Construction schedule
Walking into the living room, you will find the construction schedule of ID urban space. It has the contact information of the person in charge and the designer as well as the construction progress of the home, which can be seen at a glance. Then I reviewed the decoration company’s construction and renovation drawings.

Circuit diagram
Let us know how the wires are routed of.
Waterway direction map
After looking at the waterway direction map, you can know where there are water pipes, which are clearly marked on the map.
Switch and socket diagram
You can clearly understand all the switches and sockets in the whole house by looking at this drawing.
The acceptance process officially started
As we were talking, Supervisor Jiang arrived, all the people were present, and the acceptance process officially started. Let’s take a group photo first to show our Mr. Li’s style. The one on the left is Supervisor Jiang, the handsome guy in the middle is Mr. Li, and the one on the right is Engineer Ding from ID City Space. Then the acceptance work officially began.
First, let’s post the content of the supervision of water and electricity acceptance for everyone’s reference.
Supervisor Jiang is still very serious and responsible. Even the decoration netizens he worked for before would praise him as "extremely smart". Let’s take a look at the serious look at the construction site first.
Problems with the circuit in the living room:
The wire ends cannot be wrapped with insulating tape
The acceptance of the circuit in the living room officially began. Supervisor Jiang first asked the construction workers to open a wire box on the top. I found that the threads inside were wrapped with black insulating tape, so I immediately requested rectification. After asking, I learned that it turns out that the wire ends in the wire box need to use "wire crimping caps" instead of just insulating tape. The crimping caps have a flame retardant effect. If the circuit causes sparks, the tape is flammable.
Supervisor Jiang carefully filled out the rectification form
Bathroom circuit problem 1:
There is no pre-installed equipotential conductive wire
Later In the bathroom, Supervisor Jiang asked the construction team leader Ding to pull a 4-meter equipotential conductive wire and connect it to the metal bathtub or metal ceiling. The main function is to prevent conduction and electric shock during thunderstorms.
Bathroom circuit problem two:
The bathroom heater wire is exposed and not protected
The bathroom heater wire on the top of the bathroom needs to be covered with a hose to prevent it from leaking outside. The hose It can protect the wires outside the conduit from being damaged until the electrical appliances are installed.
Kitchen circuit problems:
The water heater socket is too close to the gas pipe, which is prone to fire
This is Master Jiang and Mr. Li studying and discussing the renovation of the water heater gas pipe situation, and also inform the gas pipeline that only the gas company or the water heater company can carry out modifications. Supervisor Jiang asked the construction workers to relocate the water heater socket because according to regulations, the gap between the socket and the gas pipe must be 15 centimeters. The switch socket will generate small sparks at the moment of startup. If the distance is too close and there is air leakage, safety accidents may occur.
Summary of rectification suggestions
After a round of inspections, Supervisor Jiang issued suggestions for rectification of water and electricity. The main contents are:
1. Equipotential pre-release lines.
2. Wrap the exposed external wires of bathroom heaters and mirror headlights with hoses.
3. The water heater socket is too close to the gas pipe and needs to be moved.
4. The tape in the wire box should be replaced with a crimping cap.
5. Holes in the wall must be filled with foaming agent.
6. The decoration company must notify the owner in advance when conducting a 24-hour water closure test
Before rectification vs. after rectification
Then Xiaoyuan and Xiaozhu asked how long it would take The rectification was completed and they said they could start the rectification as soon as possible. The construction staff of ID Urban Space were very efficient. In fact, Supervisor Jiang was already making rectification while making suggestions. After 3 hours of busy work, the rectification was finally completed. Let's take a look at the results of the rectification.
1. Equipotential pre-discharge line. Principle: Prevent conductive leakage during thunderstorms.
2. Wrap the exposed external wires of bathroom heaters and mirror headlights with hoses. Principle: Prevent injuries to the wires outside the wire conduit and play a protective role.
3. The water heater socket is too close to the gas pipe and needs to be moved. Principle: Set off explosions to prevent safety accidents
4. The tape in the wire box should be replaced with a crimping cap. Principle: The crimping cap is made of flame retardant material and is safer.
5. Holes in the wall must be filled with foaming agent. Principle: Line pipes and water pipes are soft materials, and the foaming agent is also a soft material. It will not cause damage to the line pipes as it expands with heat and contracts with cold.
Editor’s summary
Today’s water and electricity acceptance was successfully concluded. After watching the water and electricity rectification process at Mr. Li’s home, everyone must have been inspired, right? Water and electricity are the focus of concealed projects. When decorating this door, you must pay attention to safety issues to avoid future worries.
