How to Do Water and Electricity in Prefabricated Panel Houses

When doing water and electricity work in prefabricated panel houses, careful planning and standardized operations are required to ensure safety and normal functionality. The specific steps are as follows:

Planning Wiring and Pre-embedding Pipelines

Before the construction of the cast-in-place ceiling, it is necessary to plan the layout positions and directions of the water and electricity pipelines in advance. Since the prefabricated panels will be covered with concrete after installation, it is crucial to ensure that the pipeline positions do not conflict with the prefabricated panels to avoid damaging the pipelines or affecting structural safety during later construction. When planning, it is necessary to consider the functional zoning of the house and reasonably determine the positions of equipment such as sockets, switches, and faucets, and reserve sufficient lengths for subsequent connections.
During the construction of the cast-in-place ceiling, pre-embed the water and electricity pipelines: Pass the water pipes and electrical wires through pre-designed channels (such as PVC pipes) and fix them firmly to prevent displacement during concrete pouring. When pre-embedding, pay attention to the bending radius of the pipelines to avoid excessive bending that may obstruct water flow or electrical current. After construction, leave sufficient lengths at the ends of the pipelines for easy connection to equipment later, and ensure the tightness and stability of the joints to prevent water leakage or power outages.

Precautions for Prefabricated Panel Installation

The installation of prefabricated panels must strictly follow the manufacturer's guidelines to ensure flatness and stability. Special attention should be paid during the installation process:

• Avoid damaging pre-embedded pipelines: When handling and installing prefabricated panels, handle them gently to prevent bumping or squeezing the pre-embedded pipelines.
• Prohibit cutting horizontal grooves: When wiring on the floor of prefabricated panels, never cut horizontal grooves, as this will damage the structural integrity of the prefabricated panels, leading to the risk of fracture and endangering the safety of the rooms above.
• Alternative wiring solutions: Methods such as cutting grooves along the base of the wall, leading wires from the ground, or burying wires in the ceiling can be adopted. For example, when cutting grooves in the wall, cut vertically downward with a depth controlled between 1.5-2 centimeters to avoid damaging the load-bearing structure of the wall; when leading wires from the ground, lay protective sleeves in advance to prevent damage from trampling; when burying wires in the ceiling, consider the ceiling height and pipeline direction to ensure concealment and maintainability.

Connection and Acceptance of Water and Electricity Equipment

After the installation of the prefabricated panels is completed, connect the water and electricity equipment (such as faucets, sockets, and lamps) to ensure a firm and sealed connection. For example, use Teflon tape or sealing rubber rings for water pipe joints to prevent leakage; insulate and wrap electrical wire joints with waterproof tape. After connection, conduct functional tests: Turn on the faucet to check if the water flow is smooth, test the stability of socket power supply, and check if the lamp switches are sensitive. If any problems are found, promptly investigate and repair them to ensure the normal operation of the water and electricity system.
