In sprinkler or overhead irrigation, water is piped to one or more central locations within the garden and distributed by overhead high-pressure sprinklers or guns. The most common issues arising out of this system is the sprinkler heads breaking, tubing getting cut and valve issues.
In a drip irrigation system, water is piped to a central location and then to various parts of the garden through tubing with small holes placed next to plants to enable dripping of water at these spots. The most common issues arising in this system are the tubing getting cut or drip points getting blocked with sand. Sometimes, a damaged tube at the distribution point causes garden flooding.
