If you’ve ever wanted to know what sets a sprinkler drip conversion kit apart from a retrofit kit, what it comes down to is the general purpose of what the tools are being used for. For example, sprinkler conversion kits have the specific purpose of converting a sprinkler system into a drip irrigation system. In contrast, a retrofit kit might be more broadly used to upgrade any part of an irrigation system, such as drip lines, pumps, valves, and other components. A retrofit kit modernizes an existing irrigation system, while sprinkler-to-drip conversion kits change the watering method entirely.
