Tips & Advice
Will a sprinkler system use less water than manual watering?
Though it's more tedious and time consuming, manual watering uses less water than an overhead sprinkler system. However, drip irrigation is your best choice if your goal is to maximize water conservation. Drip irrigation uses pipes and valves to deliver a gradual supply of water directly to the roots of your plants. This slow delivery method gives the roots time to absorb all the water.
How frequently should a lawn be watered?
In most cases, watering a lawn once per week will suffice. If you live in an exceptionally dry climate, more frequent watering will be necessary. Conversely, if you live in an area that gets lots of rain, you might need to water less frequently. Installing a rain gauge on your lawn can help you decide if your lawn's weekly water requirements have been met. Some cities also regulate how often a lawn can be watered if there is a drought.
If a sprinkler is located on a slope or hill, this can cause water to be wasted as it drains from the system's pipes. A check valve stops this drainage by trapping water in the pipes. Drainage doesn't just waste water; it can damage your landscape by causing flooding or erosion.
What is the best time of day to water a lawn?
The best time of day to water a lawn is early in the morning before the temperature climbs. If you water when it's too hot outside, the water will evaporate before it has a chance to reach the plant roots. Avoid watering late in the evening, since this can cause water to cling to the grass overnight, creating conditions that can trigger fungus growth.
How long should sprinklers be operated per day?
To determine how long to run sprinklers, you need to know the water flow of your home's sprinkler system. Set shallow empty cans around the sprinkler heads, and let the system run for 15 minutes. Then use a ruler to measure how many inches of water the sprinklers have left in the cans. Multiply that figure by four to get your sprinkler system's hourly output. It's recommended that most grasses get 1-2 inches of water per week. If your sprinkler has an hourly output of 1 inch, running the system once every seven days for a one-hour interval will give your lawn an inch of water per week.
How much does it cost to change a sprinkler valve?
It can cost $40 or more to change a sprinkler valve. Before replacing the valve, it's important to make sure that a faulty valve is the actual cause of the problem. Sprinkler issues can also be caused by defective heads and compromised sprinkler lines. Timely repairs are important, since a sprinkler that delivers poor performance can adversely affect the health of your lawn.
What is a drip irrigation system?
A drip irrigation system is one that channels water directly to the roots of plants, distribute to plants via a network of pipes, valves, and tubing. This system aims to conserve water by minimizing evaporation, and it's the most economical irrigation choice if your goal is to minimize water consumption.
How many sprinklers can each irrigation zone have?
The amount of sprinklers recommended for each irrigation zone will depend on the flow rate of your home's water supply, which is measured in gallons per minute. Once you've decided how many sprinkler heads you plan to use in all zones, compile a total figure for all the flow rates of all the sprinkler heads combined. Divide this figure by the flow rate of your water supply. The result indicates how many zones you need, and how many sprinklers you need in each zone. For example, if you have nine sprinklers and you've determined that three zones are needed, this means you need three sprinklers for each zone.
How deep should a sprinkler system be buried?
A sprinkler system's pipes should be buried 8-12 inches below the ground's surface. Note that this measurement should be made from the top of the pipe to the surface of the soil. This means that once the size of the pipes is factored in, you'll need to dig a little deeper to meet this recommendation.
How much does it cost to install lawn sprinklers?
Having lawn sprinklers installed by a professional will cost $3,000-$4,000 for the typical 1/4-acre lot. You can save money by handling the task yourself, but keep in mind that sprinkler installation is a complex undertaking.Sound electrical knowledge is required to extend a circuit to the sprinkler’s automatic timer. And plumbing expertise is required to connect the sprinkler to your home's water system.
