1. The depth of hot and cold water pipes buried in the wall shall be 1cm between the wall of the pipe and the wall skin, strictly follow the principle of left hot right and cold;
2, the outlet must be strictly in accordance with the national standard spacing of the size of the layout, the internal and external wires to distinguish;
3, no clogging, connecting hot and cold water pressure test pump pressure 0.8MPA above no explosion, risk, drip, leakage. Unpressurized test cannot be wall-sealed;

2. The separation distance between strong and weak electricity is more than 30CM. The distance between strong electric pipe and heating pipe (piece), hot water pipe and gas pipe should be greater than 30CM;
3, the same room power, telephone, television and other outlets should be at the same level elevation (except for special circumstances), strictly follow the principle of the left zero right fire line in the ground, the best use of the national standard ground wire yellow-green line;
4, into the box line with locking protection, the laying of the box to be flat, do not elbow, bends to bend or reed handle, take over the use of PVC glue welding. Strictly follow the principle of threading after the first pipe is buried. The place where the pipe cannot be buried at the top should be protected by the square pipe, and the naked bare wire and the ceiling wire must be fixed;

6. The tube should be protected by the electric tube. When the three sets of wires enter the same box, another wire box must be provided. The ceiling box shall be reserved at the ceiling of the ceiling;
7. When the circuit project is completed, use electric light bulbs to test whether all sockets and light lines are powered on. Both strong and weak power should be carefully tested, and if the draw is a live line, it is forbidden to proceed to the next process;
8, after the acceptance to draw a precise circuit diagram to pay the owner to save (preferably to take pictures to save).
The hydropower reform refers to the renovation of all or part of the circuit used by the original developer according to the decoration configuration, family population, lifestyle, and aesthetic concept. Hydroelectric reform is divided into waterway reconstruction and circuit reconstruction.
First, the waterway transformation part of a), the material prompts according to the company quoted material selection of materials in line with national standards, construction (water supply transformation of the country is prohibited to use galvanized pipe and UPVC pipe).
b) Construction notices 1. The general water reform will not take place. The cold water and hot water outlets must be horizontal. Generally, the left heat is right and the pipelines need to be laid flat. The layout should be safe and reasonable. The location of pipe clamps, pipe slopes, etc. shall meet the requirements of the code. All types of valve installation should be correct and level, easy to use and repair.
2. The inlet valve should be equipped with an indoor main valve. Before installing, check whether the water pipe and connecting accessories are damaged, trachoma or crack.
3, the water meter installation location should be easy to read, water meters, valves from the wall to the appropriate distance, to facilitate the use and maintenance.
4. If a water softener, a water purifier, or a small kitchen treasure is to be installed in the kitchen, consideration should be given to keeping the upper and lower water positions and power supply positions in advance.
5. The cold and hot water pipes are all in the wall. When the slot is to be inspected, the depth of the slot needs to be checked. The hot and cold water pipes cannot be the same as the slot.
6. The left and right positions of the shower mixing valve are correct, and it is installed in the middle of the bathtub (the bathtub size is determined first), the height is 150-200mm in the bathtub, and the outlet of the jacuzzi is reserved according to the model. The water mixing valve hole spacing is generally maintained at (concealed) 150mm, (surface mounted) 100mm, link shower based on the height of the room and the owner's individual needs to determine the location of the outlet.
7. The water inlet of toilets should be located where they can be blocked by the toilet. One-piece toilets should be based on the model to determine the location of the outlet, generally left in the center of the toilet outlet 200 mm left.
8, electric water heaters generally need to be fixed on the load-bearing wall, if the situation is special, fixed on the non-load-bearing wall to be fixed bracket, and the top layer should have enough position to do fixed bracket, need to communicate with the water heater manufacturers in advance to determine the water heater outlet s position.
9, when installing the water heater inlet and outlet, the inlet valve and inlet valve must be considered and should be installed in the appropriate location.
10. When installing kitchen and sanitary pipes, the size of the pipe on the wall should take into account the final size of the wall tile after it is attached, ie, the thickness of the wall tile is taken into consideration in advance.
11, the design of the water pipe should be taken into account with the faucet installation location of the washing machine, the layout of the water. At the same time pay attention to the location of the power outlet is appropriate. Put the drum washing machine in the kitchen cabinet to determine the size of the washing machine and the kitchen cabinet, so as to keep the position of the water.
12. In the wall and under the ground, use as few or no connection fittings as possible to reduce the potential for leakage. The connection fittings must be installed securely and without leakage.
13. The height of the water supply outlet (elbow) on the wall should be appropriate. It is necessary to facilitate maintenance, and to minimize the exposure of the hose as much as possible, without additional hose, giving a simple, beautiful visual . For the sanitary ware such as a pedestal basin that does not have a cabinet underneath, the height of the reserved mouth is generally about 500-600 mm on the ground. The sluice basin outlet should be set in the center of the bottom of the column or behind the column, as far as possible with the column to block. Wall-mounted washbasins (without columns, no cabinets) must be provided with drainage pipes (that is, drain pipes into the wall) in a horizontal manner from the elbows at the wall.
14, after the water reform outlet and sanitary ware, water heaters and other connections, it is recommended to install the triangle valve.
11. Pipeline pressure experiment should be done after the completion of waterway reform. The experimental pressure should not be less than 0.6MPa. The time is 20-30 minutes.
c) System water pressure test requirements 1) Before the pressure test, the water valve shall be closed and the indoor piping system shall be pressurized.
2) Slowly fill the end of the pressure test pipe and drain the gas from the pipe. Sealed with water.
3) Pressure should be increased slowly with a manual pump or electric pump. After rising to the specified test pressure (8 pressures in the general waterway), stop the pressurization and observe whether there is water seepage at the joint.
4) After the pressure is stabilized, the pressure drop within half an hour does not exceed 0.05 MPa.
5) At the end of the pressure test, the original records must be made and the signature must be confirmed. 6) After the waterway reconstruction is completed, the direction of the waterway reconstruction shall be issued.
a) Material tips:
1. Choosing brand products that meet national standards.
2. The material must match the name of the product listed in the company's engineering quotation. 3. The section specifications of the used wire are 2.5mm2, 4mm2, and 6mm2. It is not affected by pulling force. It does not damage the wire core tightly, and it has no kink, dead bend, and no insulation damage. In the absence of a match, the colors of the wires used should be clearly distinguished.
b) Temporary use of electricity 1. Temporary use of electricity at the construction site shall have complete plugs, switches, sockets, and residual current circuit breakers, and temporary power must be used for cables.
2. Remove all the wires of the air switch when approaching, and then receive the temporary wiring box from the total incoming line. The engineering team shall bring its own distribution box, including leakage switch, air switch and socket with protection device. The cable shall be intact.
3, including cutting machines, angle grinders, electricity, hand drills, impact drills and other power tools, the insulation properties of the test should be intact, safe and reliable, the correct operation method.
