　　When installing plumbing and electrical systems, be sure to ensure that the waterproofing layer in the bathroom is at least 1.8 meters high; waterproofing work should be carried out only after the concealed works have been completed and passed inspection; waterproofing should be done using coating materials, and a second water-retention test must be conducted once plumbing and electrical installation are finished. In addition, areas such as floor drains, internal and external corners, and pipe penetrations must be re-waterproofed, and the floor drain pipes should be equipped with odor-control devices. A protective layer should be applied: for hot-water pipes, the protective layer should be 1.5 cm thick, so the grooves must be cut deep enough. Another important aspect of plumbing and electrical installation is to provide a service access opening for bathroom piping. The wiring should follow the standard arrangement—neutral on the left, live on the right, and ground on the right—and power and low-voltage circuits must never share the same conduit. Power outlets should be installed 300 mm above the floor, and switches 1.4 meters above the floor. Switches should not be mounted behind doors, and lighting designs should ideally incorporate dual-control switches. Provide plenty of outlets, use high-quality outlet boxes, and make sure the outlet box matches the faceplate; otherwise, it may not fit properly.

　　 Plumbing and electrical installation When installing, keep in mind that 16A outlets are intended for high-power appliances such as electric ovens; the cross-sectional area of wires in PVC conduit must not exceed 40% of the conduit’s internal cross-sectional area; and electric water heaters must be equipped with a grounding protection device. Before use, all air must be purged from the water tank, and the tank should be filled completely with water before the heater is switched on. In addition, when installing electrical and plumbing systems, pay attention to the number of wires that can be routed through each conduit: according to national standards, the total cross-sectional area of wires in a conduit must not exceed 40% of the conduit’s internal cross-sectional area. Many households today use 4mm-diameter or 6mm-diameter conduits; for example, with a 6mm conduit, the number of wires should generally not exceed five. Another important aspect of electrical and plumbing installation is proper wiring protection in kitchens and bathrooms: when installing ceiling-mounted lights or bathroom heaters, make sure to provide pre-installed wire connection points, and ensure these reserved wires are well protected—use flexible conduit to shield them from damage.
