A residential irrigation system can keep your lawn, garden, and landscaping features well watered and in good condition, without you having to stand over them with a garden hose and sprayer. An irrigation system can also mean keeping your property watered when you're on vacation or away for the weekend, so you don't come home to a wilted lawn or shrubbery. When you're ready to choose a residential irrigation system and its accessories, note a few tips to keep in mind so you know you opt for the right variety.
