A. No. -- In fact, an automatic sprinkler system may actually save you water. A well designed, efficient irrigation system applies exactly the amount of water needed by your landscape. You will never again have to worry about wasting water if you forget to turn off the hose. Plus, with a Rain Bird rain shut off sensor your system will know when it is raining and simply turn itself off when water is not needed.
A. Yes. -- You won't have to spend another minute of your valuable leisure time watering the lawn. Your new system will do all the watering for you - even when you are away from home!
A. An automatic sprinkler system will do a more efficient job because it will be designed based on your landscapes diverse watering needs, using specific products designed to water grass, trees, shrubs or garden plants.
A. If it rained at your house every three days -- the same exact amount each time -- you probably would not need a sprinkler system. But nature doesn't work that way, and the only way to ensure healthy, lush yard is to make certain that your lawn and plants receive a regularly timed and evenly measured amount of water. In the dry season when there is little or no rain, your plants can suffer stress and damage after just a few days without water.
A. A typical system is comprised of a controller (which functions as the brains of the system), valves (which open and close to release and stop the flow of water to underground pipes) and sprinklers (which distribute water to specific areas). The sprinkler system can be customized further with rain shut off devices, soil moisture sensors and drip irrigation zones.
It is best if all of a system’s components are manufactured by the same company in order to ensure that they will work well together. Rain Bird designs and manufactures the most complete line of components that make up an efficient irrigation system. Northwest Iowa Sprinkler can help you choose and install the right Rain Bird product for your landscape’s diverse watering needs.
A. You can install an automatic sprinkler system on your own. As with any home improvement project, you should consider all the aspects of the project before you begin.
- Understand the time and tools necessary to complete the job. Consult local hardware and plumbing stores, or nurseries for more information on the tools necessary to complete the installation. Depending on the size of your property, installing a system could take more than just a few days to complete.
- Always consult local plumbing and electrical codes. Most municipalities require a backflow preventer to prevent the flow of irrigation water into the main drinking water supply. It is better to know the code requirements before you begin the installation to avoid costly mistakes.
If you already have an existing lawn and landscape you might need to move plants, trees or shrubs in order to install the system. Make sure you have prepped the area before you begin the installation.
A. It depends. Remember, product cost is only one part of an efficient irrigation system. Many people choose to hire an experienced professional irrigation contractor who will bring years of experience designing and installing the most cost-effective and efficient irrigation systems. Contractors have also invested heavily in specialized installation equipment to help speed up the job and many have gone through detailed training courses and certifications.
A. If you decide to hire a professional irrigation contractor, here are some tips that will help you select the right contractor for the job.
- Before a contractor can present you with a bid, they must do their homework. This includes coming to your property, meeting with you face-to-face, surveying and sketching out the property, locating the water source, taking a read of the water pressure and finally, understanding your needs and what you want to accomplish.
- Experience does count – make sure you are comfortable with the experience level of the contractor. If you are not sure, the best reference is a recent customer.
- It's not all about price – often times, we use price as the only deciding factor. Contractors who have a significantly lower price than their competition have to cut corners in order reduce their costs. This could mean leaving out a backflow preventer, not using the proper installation techniques or even, not completing the work. Make sure you have selected a contractor based on their service, design plan and ability to install the system properly.
- If you need help finding a contractor in your area, Rain Bird’s Contractor Referral Service can assist you in finding a prequalified contractor in your area.
A. The price of a system depends upon many factors such as property size, type of landscaping, number of zones, products used and special designs.
Whether you work with a qualified professional irrigation contractor or decide to install your own system, you can rest assured knowing that Rain Bird products will deliver maximum results. Rain Bird, as well as its nationwide distributor network, stands behind all of its products and is serious about its commitment to quality construction.
We get asked a lot Is it Expensive?
If you hire a sprinkler company that offers you a $2500 system and the company does not draw up a custom design, does not include any water saving features, does not have a service department and you end up with a system that does not perform as you expect, THAT'S EXPENSIVE!
Prices for an underground lawn sprinkler system can differ, widely, depending on the expertise of the contractor and the quality of the products installed as well as the size and shape of your lawn. For an average-sized lot located in the middle of the block, the price will range from $3,000 to $4,000.
A. Rain Bird offers a wide selection of the most advanced sprinkler timers and controllers that are powerful enough to meet your customized watering needs, while being simple to program and adjust. The newest Smart controllers from Rain Bird even adjust themselves automatically based on changing weather, temperature and rainfall, so all you need to do is sit back and relax.

A valve configured so its outlet is oriented 90 degrees away from its inlet. In irrigation, these valves are generally installed with the inlet at the bottom of the valve.
A type of backflow preventer which seals off the atmospheric vent area when the system is pressurized. Should be installed downstream of a control valve in a location which is at least twelve inches higher than the highest point in the lateral which it serves. When system pressure drops to zero, the float and seal assembly drops, opening the vent to atmosphere and breaking any siphon effect. Consult local building codes or your Rain Bird distributor for laws applicable in your area. Synonymous with Atmospheric Vacuum Breaker.
A measurement of the volume of water applied to landscape in a given time. (In the United States, usually expressed in inches per week. Its metric equivalent is centimeters per week.)

A valve which is activated by an automatic controller using electric or hydraulic means. Synonymous with Remote Control Valve.
The unwanted reverse flow of liquids in a piping system.
A mechanical device which prevents backflow. In irrigation, it is used to protect the potable water supply from potentially contaminated irrigation water. There are several types of backflow preventers. The choice of backflow preventer used depends on the degree of hazard and the particular piping arrangement involved. Virtually all regulatory agencies in the United States require backflow prevention devices to protect the domestic water supply from contamination by the backflow of irrigation water. In areas where it is not required, it is highly recommended. Consult local building codes for laws applicable in your area.
A controller feature that allows you to suspend watering on a specific date.
A valve which allows water to flow in one direction only. Check valves are used to prevent low head drainage.
A numerical expression which serves as an index for the uniformity of water applied to a given area within a specific geometric arrangement of sprinklers (e.g., square or triangular).
This is the brain of the sprinkler system. The controller automatically opens and closes valves according to a preset schedule. Rain Bird controllers have easy-to-set programs to help you efficiently manage seasonal adjustments. Rain Bird also has sensors that signal the controller to shut off the system when it rains. An automatic controller is usually more water-efficient that operating sprinklers manually.
The area of landscape watered by a sprinkler or grouping of sprinklers.
Rain Bird 's exclusive feature which allows you to break the total irrigation run time into shorter cycles, segmented by breaks or soaks during which the landscape has time to absorb the water. Optimizes the watering of poor drainage sites, slopes, and heavy soil areas. Helps to prevent run-off.
Rubberized seal which keeps water from flowing through the valve.
A calculated value that shows how evenly water is distributed in a sprinkler system to avoid excessively wet or dry areas in the landscape. It depends on the spacing of sprinklers, type of sprinkler used, wind and water pressure among other factors. High distribution uniformity is obtained when an equal amount of water is placed on all areas of the landscape.

The quantity of water needed by the landscape to satisfy the evaporation, transpiration and other uses of water in the soil. The Irrigation requirement is usually expressed in depth of water and equals the net irrigation requirement divided by the irrigation efficiency. (In the United States, usually expressed in inches per week. Its metric equivalent is centimeters per week.)
The pipe installed downstream from the control valve on which the sprinklers are located.
Residual flow from low-elevation sprinkler heads in a system after the control valve has been closed.
A pipe under constant pressure which supplies water from the point of connection to the control valves.
A valve used to protect the landscape from flooding in case of a ruptured main or malfunctioning downstream valve. The master valve is installed on the mainline after the backflow preventer and the control valves.
Matched precipitation rate (MPR) refers to sprinklers that apply water at the same rate per hour no matter the arc of coverage or part of a circle they cover. For instance, a full-circle sprinkler discharges twice the flow of a half-circle sprinkler and a quarter-circle sprinkler discharges half of what the half-circle unit does. MPR allows the same type of sprinklers, no matter what their arc, to be circuited on the same valve and to deliver the same PR rate. Spray heads have fixed arcs and are matched by the manufacturer, while rotors offer a choice of nozzles to match the Designed arc pattern.
The unique environmental conditions in a particular area of the landscape. Factors include amount of sunlight or shade, soil type, slope and wind.
A device which monitors the amount of water present in the soil and modifies the watering schedule accordingly.
Male nominal pipe thread.
The final orifice through which water passes from the sprinkler or emitter. Nozzle shape, size and placement has a direct effect on the distance, watering pattern and distribution efficiency.

An electromagnet which is connected to a controller and causes the opening and closing of automatic control valves.
A hydraulically operated mechanical device which discharges water through a nozzle or nozzles.
When you program a controller, you schedule the precise time you want to begin watering on water days. The start time is the time the first station in a program begins to water. All other stations in the program follow in sequence. Remember, start times usually apply to the entire program, not to the individual stations.
The pressure in a closed system, without any water movement.
A circuit on the controller which activates a single control valve in the irrigation system to control watering for a particular zone.
A spring-loaded check valve used beneath a sprinkler to prevent low-head drainage. The check valve feature may also be built into the sprinkler.
An assembly of flexible swing pipe and fittings that are used to connect a sprinkler to the lateral pipe. Allows you to easily adjust the sprinklers to grade level and also helps to prevent breakage due to force on the sprinkler.
