A proper working sprinkler system will save you time that you would be using to water your lawns and gardens. A sprinkler system can also save you money and water using only the amount of water that is necessary, especially through the current drought conditions.
Having a sprinkler system would also minimize the amount of weeds growing on your lawn. If one or one more of your sprinklers are not working properly, it could result in an uneven distribution of water to your lawn. Broken sprinklers cause floods, puddles, and increase water bills.
