After purchasing a new home and accepting it, one more important thing came one after another - decoration. The renovation of the house's water and electricity is an indispensable and important part of the renovation process. Let's take a look at the relevant knowledge of the house's water and electricity decoration process and precautions today. Hope to help friends who have this need!
Water and electricity decoration notices need to be prepared before the renovation
1. The house is completed and the decoration procedures have been completed;
2. Changes in the interior wall structure (removal of walls or new walls);
3, furniture, electrical basic specifications, placement
4, the top ceiling lamp layout
5, floor plan and modeling lamp layout
6, other personalized needs
7, kitchen cabinet designer to determine the kitchen socket, the basic positioning of the lamp
8ã€How to supply hot water for your home, gas heating or electric water heater or other hot water supply
9, determine the water heater size specifications, ordinary bathtub or Jacuzzi
10. Make an appointment in advance for the accurate positioning of the hydropower engineer's home planning and make an on-site project budget.
Water and decoration renovation notes of the decoration process:
1. Positioning of hydropower. According to the needs, the position of the switch sockets of the whole house and the position of the waterway interface are determined. Attention should be paid to the principle of "water goes by the sky and electricity goes by the ground", that is, water pipes go to the ceiling, and strong and weak electricity go as far as possible on the ground, and strong and weak electricity cannot cross each other and the parallel distance is more than 30 centimeters.
2. The installation and design of the distribution box and information box should be considered for ease of use, concealment, and safety. Attention should also be paid to the direct connection with the outside main line; the electrical lines must not be hidden within the building's load-bearing wall or column.
3. The electrical circuit design of sockets, switches, and lamps must take into account the variability of the interior space, prepare for possible different space usage conditions, and reduce the barriers to re-planning and design of some users during use, such as desks, decorative cabinets, The movement of electrical equipment affects the use of electricity and water.
4, in the case of a large lamp weight, pay attention to the embedded load-bearing components in the ceiling, can not be installed directly on the wooden wedge, so as not to cause indoor unsafe factors.
5, after the positioning of hydropower, the next step is to play slot. The slot played by a good groover is basically a straight line, and there are basically no hairs in the groove. Before making a groove, be sure to have a plumber mark all the water and electricity on the wall. Remember to compare the hydropower diagrams and see if they are consistent.
6. When the waterway is reformed, pay attention to the surroundings must be tidy. When waterway reconstruction is contracted, it is better to indicate the materials used for waterway reconstruction. In addition, the size of the water pipe in the original room should be taken into account in the reconstruction of the waterway, and the pipe of the external water pipe should be matched with the original water pipe. Hot and cold water pipes should be left hot right cold, the spacing is generally not less than 20cm, depending on the distance between the hot and cold pipe taps.
Notice of hydroelectric power decoration decoration
1. The installation position and quantity of switches and sockets should be carefully considered when wiring. The principle is that it should not be less.
2. Under normal circumstances, the zero line is blue, the fire line is red, and the ground line is a yellow-green two-color line.
3. The cross section of each residential house entrance line should not be less than 10 square millimeters. This way, for ordinary families, the lamps and lanterns use 1.5 square millimeter lines, and the switches, sockets, and grounding lines can be used for 2.5 square millimeters, and for installing air conditioners, etc. Lines of high-power electrical appliances should go on a single 4-square-mm line. For the entire line, the number of branch circuits should not be too small. Generally, the lights should go all the way, air conditioners go two ways, and outlets go three to four ways. The advantage of this is that once a circuit has a short circuit or other problem, the scope of power outage is small and it will not affect the normal operation of other circuits.
4. The height of switches or sockets in the same room must be the same. Generally, the switch is 1.4 meters away from the floor and 15 to 20 cm away from the door frame. 30cm from the socket is appropriate. The air conditioning hook socket is more than 2 meters above the ground, and the cabinet socket is 30cm above the ground. The kitchen socket is 1 meter off the floor (the height of the kitchen cabinet is about 80cm). Sockets on the countertop: such as bedside cabinets, vanity units, kitchens, etc., the bottom of the outlet should be 10cm from the countertop. Bedside double control switch height is about 85cm; Wall TV power supply height is determined according to the space size and TV size, the general height is 1000-1200MM.
5, in the wiring process, to follow the "fire line into the switch, the zero line into the lamp" principle; socket wiring to do "left zero N right fire L, ground PE on the" or "flame under zero." To prevent children from getting an electric shock, touching with a finger, or inserting a metal object into the power hole, be sure to use a safety socket with a safety cover. In addition, electrical appliances that need to be switched on and off frequently should be considered as outlets with switches.
6, the living room lighting should be installed in front of the entrance door and the bedroom door double control switch (so that at night to go to bed, go directly to the bedroom off the lights and then go to bed, do not touch the black door to find the bedroom). Similarly, bedroom lights should be installed in the bedroom door and bedside dual control switch. In addition, bedside lamps are recommended to install wall lamps instead of table lamps (space-saving).
7, into the account or bathroom mouth, you can consider installing infrared sensor lights (go home at night or get up, do not touch the black switch).
8, strong and weak electricity need to be slotted, separate laying (the spacing of strong and weak electricity should be 30-50 cm), and use cold pipe to thread (cold elbow pipe tool to use, arc should be the diameter of the line pipe 10 Times, so that threading or stitches can be smooth.
9. The principle of hydropower construction is that if you go to the top and you don’t go to the top, you can’t walk. Consider taking the wall and the wall can’t go before you consider taking the ground. The top line is inside the ceiling or plaster line, which is easy to overhaul.
10. Household units should be provided with their respective power boxes, and a leakage protection device with an operating current of 30A should be provided in the distribution box. After the splitter passes through the air, it controls the lighting, air conditioning, and sockets.
Water Renovation Notes Water Decoration
1, the water pipe away from the wall as much as possible.
2. PPR pipes for water pipes, red hot water pipes for the pipelines, and cold water pipes for the baskets. 
3, PPR water pipe specifications: water pipes in accordance with the size of the inner diameter can be divided into 20mm, 25mm and 32mm, of which 20mm is relatively thin, commonly known as 4 in charge of, 25mm is commonly known as the 6 in charge (home improvement pipe is recommended to use 6 in charge), 32mm It is generally used for households; in accordance with the wall thickness, it can be divided into 2.8mm and 4.2mm, 2.8 is a cold water pipe, 4.2 is a hot water pipe, generally we are using 4.2mm thick.
4, hot and cold water pipes should be left hot right cold, hot and cold water joints spacing of 15cm, 1-1.200m from the ground. The height of the upper flap washing machine outlet is 1.2M. Basin, vegetable basin water outlet height 45-55cm.
5, if there is natural gas supply, preferred gas water heater, available for kitchen or bath water. If you are far away from the water heater, consider installing kitchen treasure separately.
Reminder of water and electricity decoration tips:
1. It is not advisable to slot the jumper pipe on the ground freely to avoid the pipeline area.
2. It is not advisable to punch and fix the pipeline at the ground to avoid the pipeline area.
3, open the cassette to avoid the steel bar can be moved up and down or even change the position, prohibiting broken ribs.
4, can not open long transverse trough: the load-bearing wall is easy to damage the structure, light wall due to the force of the upper and lower three sides, after the broken tendon will cause trouble.
5, wire and pipe should not go inside the plaster line, easy to cause dead bent, dead line.
6, PVC pipe diameter less than 25 bend pipe bender, can not add bends elbow; circuit is not a show, bends to avoid bending at right angles.
7, in addition to the kitchen and bathroom, the circuit to take the pipeline as far as possible (except the top of the ceiling), walk the end of the use of PVC adhesive bonding interface.
8, the first line of the layout is completed, fixed is completed, and then threaded and steel wire.
