The layout of the water and electricity system in a mobile home needs to balance flexibility, safety, and convenience for daily use. Its design should revolve around functional zoning, pipe routing, equipment selection, and future expandability. First, the functional zones of the house must be clearly defined, such as the usage needs of bedrooms, kitchens, and bathrooms. Bedrooms should have bedside sockets, lighting switches, and network interfaces for convenient nighttime power use and smart device connectivity. Kitchens should have centralized sockets for high-power appliances such as induction cookers, microwaves, and rice cookers, and these sockets should have switches to avoid frequent plugging and unplugging. Bathrooms require careful consideration of waterproofing and moisture prevention; sockets should be splash-proof, and dedicated circuits for appliances such as water heaters and washing machines should be provided.
The routing of water and electricity pipes should follow the principle of "horizontal and vertical" to avoid intersections and reduce signal interference and maintenance difficulties. PPR pipes are recommended for water pipes, as they are corrosion-resistant, high-temperature resistant, and have a long service life. Hot and cold water pipes should be laid separately with a certain distance between them to prevent heat from the hot water pipes from affecting the cold water pipes. For electrical wiring, copper core wires conforming to national standards should be used. High-voltage and low-voltage wiring must be separated. High-voltage wiring includes lighting and sockets, while low-voltage wiring includes network and television wiring. A certain distance should be maintained between the two. If necessary, low-voltage wires can be wrapped with aluminum foil to reduce static interference. When laying conduits, try to run them along wall corners or ceilings for easy future maintenance and concealment. Avoid cutting long horizontal grooves in load-bearing walls to prevent damage to the building structure.
The water system for a mobile home requires careful consideration of water supply and drainage layout. For water supply, a larger diameter main pipe is recommended to ensure stable water pressure when multiple devices are using water simultaneously. Branch pipes should be selected according to the needs of each water point. Separate hot and cold water pipes should be installed in the kitchen and bathroom, with interfaces reserved for water purifiers, garbage disposals, etc. The drainage system should have a reasonable slope to ensure smooth sewage discharge. Floor drains should be located away from high-traffic areas to prevent odor spread. Odor-proof floor drains are recommended for bathrooms, with proper waterproofing. The waterproof layer on the walls must meet certain standards, and a water-retaining strip should be installed on the floor to prevent water overflow. Electrical safety is central to water and electricity layout and must be ensured through the proper design of circuits and protective devices. High-power appliances such as air conditioners and water heaters should have independent circuits to avoid overload risks caused by sharing circuits with other appliances. Lighting and socket circuits should be separate to prevent socket circuit failures from affecting lighting use. All sockets should be equipped with leakage protection devices, especially in damp areas such as kitchens and bathrooms, to reduce the risk of electric shock. The height of switches and sockets should be ergonomic; for example, bedside sockets should be a certain height from the ground for convenient mobile phone charging, and kitchen countertop sockets should be a certain height from the countertop to avoid excessively long appliance power cords.
The flexibility of a mobile home requires the water and electricity system to be expandable to adapt to future functional changes. For example, blank wiring channels or interfaces can be reserved in the walls for easy addition of sockets or network points later; branch valves can be installed on the main water pipe for easy local maintenance or modification. If smart home devices are planned for installation, wiring and interfaces need to be planned in advance, such as reserving power and signal lines for devices like electric curtains and smart toilets. In addition, the water and electricity layout should be coordinated with the overall house design; for example, concealing pipes behind furniture or decorations is both aesthetically pleasing and easy to maintain. After the water and electricity layout is completed, a rigorous acceptance inspection is required to ensure the system's safety and reliability. Water pipes must undergo pressure testing to check for leaks; electrical wires must be tested for continuity to confirm all sockets and switches are functioning properly, and a phase detector should be used to check the wiring for correctness. During acceptance, the secure fixing of pipelines must also be checked to prevent loosening due to vibration later. Regular inspections of water and electrical equipment are necessary during daily use, such as cleaning floor drains and checking socket temperatures, to promptly identify and address potential problems and extend the system's lifespan.
The water and electricity system layout of a mobile home should be guided by safety, practicality, and expandability. Through scientifically planned functional zoning, rationally designed pipeline routing, selection of high-quality materials, and provision of expansion space, it meets daily living needs while providing convenience for future upgrades. Strict adherence to construction specifications and acceptance standards ensures the long-term stable operation of the water and electricity system, providing residents with a safe and comfortable living environment.
