The old house hydropower transformation process
What the owner needs to prepare before remodeling:
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.
Before the construction, sign the hydropower reform contract
1. Make an appointment in advance for the accurate positioning of the hydropower engineer's on-site planning, and make a project budget on site. If the construction does not change one point, the error value should not exceed 10% to avoid over-expenditure during settlement;
2. The water circuit reform contract should be determined: water pipes, pipe fittings, BV single copper wire, UPVC flame-retardant electrical pipe, network cable, television cable, telephone cable, audio cable and other material brand models to prevent material counterfeiting;
3, hydropower reform contract should indicate the unit price of each purpose, the total budget, and the error value
During Construction: Precautions in the Construction of Water Circuits and Some Regular Sizes
1, shower outlet from the ground 1100mm
2. Satellite TV sets the south facing windows of the room. The southwest direction is commonly used by taiwan Chinese live (entertainment, national language), and the southeast is CNN, BBC, HBO and other full English programs. Place specific locations based on personal preferences.
3, socket position and the original socket to maintain a relatively consistent height, generally 300-350mm
4, dual control switch from the ground 850mm
5, wall-mounted TV power supply distance 1100-1300mm
Old house hydropower transformation precautions
1. It is not advisable to slot the jumper pipe on the ground 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 bend, 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. Except the kitchen and the kitchen, the circuit should take the pipeline as far as possible (except the top ceiling), and the PVC pipe is used to bond the interface.
8, the first line of the layout is completed, fixed is completed, and then threaded with steel wire
9, waterproof construction should use waterproof coating
10. Waterproofing works should be done after the hidden construction is completed and accepted
11. Do two water storage tests after waterproof construction is completed
12, the bathroom waterproof layer should not be less than 1.8 meters
13, floor drain, Yin Yang angle, pipelines and other places to do more waterproof
14, floor drain to use deodorant floor drain
15, hot and cold water left hot right cold
16, try not to walk from the ground
17, cold water pipe in the wall should have 1CM protective layer, hot water pipe is 1.5CM, so the slot to open deep
18, PPR pipe is installed to consider the thickness of the paste tiles, so that the pipe will not be exposed
19, the washing machine to consider whether it is drainage or drainage
20, weak electricity can not be worn in the same pipe
21, left zero, right phase grounded
22, power socket 300, switch 1.4 meters
23, switch not installed behind the door
24, a lot of sockets should be good
25, high power appliances with 16A socket, such as electric oven

27, cassette must be matched with the panel, otherwise it may not be installed
28. The cross-sectional area of ​​the wires in the PVC wire conduit must not exceed 40% of the cross-sectional area of ​​the wire conduit
29, bedroom air conditioning do not face the bed
30, air conditioning hole to consider outward tilt, otherwise the rain will come in
31, lights try to consider dual control
32, the best bathroom to install splash socket
33, on the balcony to consider a socket
34, wire troughs should be horizontal and vertical, row photos, later use it
35, public flue to install the reverse valve
36, bought the appliance must be good for workers to read the instructions
37. Instructions and warranty cards must be kept
How to perform immediate acceptance after water circuit construction
1. Water acceptance: After the water reformation is completed, the cold and hot water pipes have been reformed with a hose to ensure that the hot and cold water pipes of the entire indoor pipe are pressed at the same time; the pressure suppressor is installed, the pressure suppressor is filled with water, and the air in the pipe is let off, so that the entire circuit is inside. It is all water; close the water meter and the outside gate valve (make sure to protect it). Then began to suppress, the experimental value is 1.5 times the working pressure, 30 minutes impermeable, pressure drop does not exceed 0. 05MP is qualified
2. Strong power acceptance: Use 500V insulation resistance meter to test the insulation resistance value of each circuit, and at the same time, it can test the quality of the used wires. Wires that do not meet the standard may be broken down;
3. The weak current adopts the special tool test: The special network test tool tests whether the 8-core signal of the network is unimpeded; the carrier's copper shaft cable test tool, the multimeter and other complete tests are qualified before the next construction work.
4. It must be noted that the completion of the hydropower reform must be checked and accepted, and it will be too late to wait until the completion of the construction of other projects.
Editor's summary: The price of this hydropower reform must be known, because each home will have hydropower reform, master the approximate price of hydropower reform, in order to do a good job in fitting out the budget for the price, to avoid overspending.
