The installation of water and electricity for container houses, folding houses, modular buildings, and prefabricated space cabin houses can be carried out according to the following steps

Reserved pipe holes: Reserve holes for water pipes and cables on the container walls and floors as needed. Ensure that the hole size is appropriate and treated with waterproof sealing material to prevent water leakage and wire short circuits.

Installation of water pipe system: Install cold and hot water pipe systems according to the location and layout design of the water source. Connect faucets, sinks, showers, and other equipment, and use appropriate connectors and sealing materials to ensure secure connections without leaks. 

Install the wiring system: Install the wiring system according to the power supply location and wiring design. Connect switches, sockets, lighting fixtures and other equipment, and use appropriate wire specifications and protective devices to ensure the safety and reliability of the circuit.

Connect to external supply: If necessary, connect the water pipe system to the external water supply network to ensure reliable water sources and meet usage needs. At the same time, connect the electrical system to external power lines to obtain a stable power supply.

Testing and acceptance: After completing the installation of water and electricity, conduct system testing and acceptance. Check whether there is any leakage in the water pipes, whether the circuit is running normally, ensure the stability and reliability of the water and electricity system, and comply with relevant safety standards and regulatory requirements.

Please note that when installing water and electricity, it is recommended to seek the help of professionals to ensure safety and compliance with regulatory requirements
