How should irrigation wire be spliced safely?

Using waterproof connectors is the safest method for splicing irrigation wire. This approach ensures that the connection is secure and protected from moisture, which is crucial in irrigation systems that are often exposed to wet conditions. Waterproof connectors prevent corrosion and potential short circuits, extending the life of the wiring system. They help maintain continuous electrical conductivity and reliability, reducing the risk of failure in the irrigation system.

The other methods lack the necessary protection against environmental factors, which can lead to issues such as short circuits, electrical failures, and decreased efficiency of the irrigation system. Standard electrical tape, while it may provide some insulation, does not create a secure and lasting waterproof seal. Similarly, simply twisting wiring together exposes connections to moisture and can lead to corrosion over time. Leaving wire ends exposed is a safety hazard, as it increases the risk of electrical shock and shorts, as well as damage to the wiring itself.
