A, water and electricity installation specification
1, wiring principle: horizontal and vertical. Use special Cai Zhong PVC flame retardant conduit, which must be fixed in the conduit. When the conduit box is connected with the conduit, lock nuts shall be used, and a pipe clamp shall be used every 80 cm for the straight pipe and every 20 cm for the corner.
2. The socket is on the upper part of the wall, and the wall is vertically slotted upward to install decorative corner lines at the top of the wall. If it is in the lower part of the wall, the socket should be slotted vertically downward to the bottom of the skirting board, and the depth of the slot should be consistent. Grooved lines and tops should be ejected from the wall first, then cut the wall with a cutting machine and slotted with a machine.
3. When using Cai Zhong PVC pipes, we now use springs to bend them instead of 90-degree elbows and tees (at this point, we have hardly seen this situation at present). When installing the line, it is necessary to add a protective line sleeve and connect it with glue. The edge of the sleeve should be straight, tight and smooth. At the right-angle corner, the inside of the corner should be cut off. After cutting off the arc interface, one side of the cut should be bent and installed.
4. Pipe thread depth is moderate, without burr. Wrap the joint of the pipeline with raw material tape for 5 -6 times, and the number of winding teeth of the pipeline is 5-6, until the joint is tightened, and rotten teeth are not allowed to be inserted into the pipe.
Second, the standard size of water and electricity installation
1, washbasin: 50cm shower: 120cm toilet: 20cm vegetable basin: 120cm electric water heater: 40cm mop pool: 75cm washing machine: 170cm gas water heater: 130cm bathtub: 35cm cold.
2. Common dimensions of kitchen equipment: the height of the kitchen cabinet console is 810-850 mm; The front-back depth is 500mm-600mm from the operating table to the bottom of the cabinet. The height is about 550mm, neither too high nor too low is good. The shower outlet of the hanging cabinet is 1 100mm from the ground.
3. Satellite TV is equipped with a south-facing window, which is often used to broadcast live programs (entertainment, Mandarin) aimed at Chinese in Southwest Taiwan Province Province, as well as all English programs such as CNN, BBC and HBO in Southeast China. Choose according to actual needs.

5. The double control switch is 850mm from the ground.
6. The height of the wall-mounted TV power supply from the ground is about 700 mm (1100-1300mm). It is laborious to put things too high, the thickness is 300-350 mm, and the height of the range hood is a standard height above the kitchen countertop. In case of special circumstances, the distance from the bottom of the machine can be appropriately changed to 750 mm
The water and electricity installation specifications are as above. You must find a professional master of the water and electricity company and let them complete the relevant work for you according to the relevant installation specifications. The standard size of water and electricity installation is as above. If the products with relevant specifications are used correctly during water and electricity installation, the final effect of decoration can be better.
