Living landscapes need water to survive and flourish, and relying completely on natural rainfall sometimes isn't the best method of supplying water. With the convenience of spraying water directly where it needs to go, and the ability to automate your watering schedule, an underground sprinkler system might be the best irrigation for your needs. Installing your own home irrigation system can save you money. However, it's not one of the easiest do-it- yourself projects around. To decide if you really need an underground irrigation system consider: • The type of grass in your lawn affects irrigation needs. • Some turfgrass varieties have higher water requirements than others. Irrigation Design Software. But Anderson can draw in the sprinkler heads, for example, and the program will automatically draw the pipe in between and calculate. Pope accepts no liability for design failure, inaccuracy, or incorrect product, purchasing or design information within this program. I agree or I do not agree. • Your soil type also affects the efficiency of irrigation. For example: sandy soils absorb water more quickly than clay. • An irrigation system gives you better control of the moisture content of your soil, but if you supply more water than the soil can absorb, runoff is the result. Planning and purchasing the correct components are the keys to success. But don't be discouraged, most manufacturers of home irrigation systems have design and planning guides that simplify the job considerably. To decide whether to do it yourself or hire a pro. Before installing a permanent irrigation system, you'll need to: • See if your locality requires a building permit. • Check for underground utilities before digging. Before you begin any excavation (that means even digging a hole), you've got to call and check for underground utilities. • Research your local municipal watering ordinances. • Find out if your state/local regulations require a licensed professional installation. In order to purchase the right components, you'll also have to determine your own specific: • Water pressure in pounds per square inch ( PSI). • Water meter size (for a municipal system) or well pump size (for a well). • Water service line size. • Water flow rate in gallons per minute ( GPM). • Type of backflow prevention required by local code. There are two measurements of water pressure, working (when the water supply is turned on) and static (when the water supply is shut off). Download connectify free version. You'll need your working water pressure number. Checking your water pressure requires a pressure gauge. If you can't borrow one from a plumber buddy, you can. The gauge attaches to the outside faucet and provides a pressure reading in pounds per square inch (psi). Make sure all other water faucets (indoors and out) are turned off when you take the reading. You can also get your water pressure from your local municipality, but it's likely to be an average for the neighborhood rather than for your home specifically. Flow rate is measured in gallons per minute ( GPM): • Using your outside spigot, fill a measurable container with water. • Record the time it takes to fill to a measurable level - a gallon is the easiest amount. • Divide the filled container size (in gallons) by time (in seconds) it takes to fill it. • Multiply it by 60 seconds. • The number you get is the flow rate in GPM. Multiply that number by 60 if you need to determine gallons per hour ( GPH). Example 1 Example 2 A 3-gallon bucket takes 15 seconds to fill.3÷15 = 0.2 0.2x60 = 12 GPM or 720 GPH A 4-gallon bucket takes 30 seconds to fill.4÷30 = 0.130.13x60 = 7.8 GPM or 468 GPH. When you've completed all of the preliminary research, it's time to start laying out your system.
