Frequently Asked Questions


Why should I get a sprinkler system installed in my yard?

Well there are several answers and they are all correct!

For instance, many people have installed their irrigation system for the convenience.  They may not want to water by hand, and may not want to hassle with remembering to shut off the water during the heavy rains of monsoon season.

Many people have installed a sprinkler system so that they can extend their plant life.  Regular watering has been shown to improve the plants health and appearance.

Many people install a sprinkler system to save money and conserve water.

And still many more people have installed a sprinkler system to increase the market value of their homes.  Remember, the key factor in determining the market value is the appearance of the home, and a green lawn and plant life will help you do that.

What are the elements of an automatic irrigation system?

Controller/Timer

The controller, or timer, is the brain of your system, telling your sprinklers what day, what time and exactly how much to water.

Valves

Installed above or below the ground, usually near the water source, valves regulate water flow to the sprinklers.

Pressure Vacuum Breaker (PVB)

PVBs prevent water from your sprinkler system (and therefore any fertilizer or chemical contaminants) from re-entering the clean water supply. Toro® manufactures several pressure vacuum devices to meet your local building code specifications.

Lawn Sprinklers

Installed in a particular pattern for complete and even coverage, a properly designed automatic irrigation system delivers precise coverage without gaps or runoff.

Drip Lines/Bubblers

Installed near plants that only require small concentrated  amounts of water throughout the day.

 

How much should I water my yard (Lawn)?

You don’t necessarily need to soak your lawn. The important rule is ensure that the roots are moist. This can usually be achieved with one to two inches of water a week. Consider yourself lucky if Mother Nature takes care of this for you on occasion. Don’t stress if you miss a week once in a while.

 

How to Conserve Water with an irrigation system?

Conserving water is smart for the planet and for your budget. Here are some simple irrigation tips that you can use to save water:

  • Always use “head-to-head coverage” in your irrigation system.
  • Keep the soil regularly moist. Ensure there is no runoff, to make sure your plants have a steady supply of water, but you are not wasting.
  • Water in the early morning – evaporation is minimized and the lawn utilizes the most water.
  • Do not water midday – the majority of water evaporates, and your lawn may burn.
  • Create multiple programs for your sprinkler system this allows you to irrigate most efficiently.
  • Install a rain sensor, it will prevent the system from running during a rainstorm.
  • Use drip irrigation in flower beds and on shrubs and trees – it saves substantial amounts of water.
  • Reduce run times for zones that are shaded.
  • Allow grass to grow before mowing – this reduces water usage.
  • Practice “grass cycling” this reduces water loss due to evaporation, while reducing the need for fertilizer.
  • Aerate your lawn – it prevents soil compaction and allows water to soak in faster.
  • Keep plants with different watering needs on different zones trees vs. lawn, etc.
  • Plant native species, native plants do better and need less special care than exotics.
  • Purchase irrigation products designed to conserve water.

How to choose a backflow device for an irrigation system?

In most homes the landscape irrigation system and the potable water system are one and the same — there is no separation. Here’s where the danger comes in. Sprinkler lines lay in gardens and lawns that are often sprinkled with weed killer, pesticides, and other poisons. Irrigation systems occasionally draw water inward (backwards). This phenomenon is known as a siphon or backflow. Backflow can result in contaminated water at a tap inside the home. Is there any wonder why the building code requires that all outside irrigation lines have some sort of anti-siphon protection?

Backflow can be defined as the unwanted reverse flow of any liquid, solid or gas in a piping system.  In an irrigation application, this means that water within the irrigation system may find its way back into the potable (drinkable) water system during a backflow incident.

When should I water my lawn?​

Water in the early morning (before sunrise) when water pressure is greatest, evaporation is minimal and the lawn drinks in the most water. Do not water in the evening because water will sit on the lawn and may cause disease. Do not water in the heat of the day because the sun will evaporate water before it can soak in. To water your lawn efficiently, you need to provide the right amount of water, evenly distributed, in the right places and at the right time
