Frequently Asked Irrigation Questions

Q:  How will I benefit from an inground sprinkler system?

A:  Since handwatering is done on a random basis, and at irregular intervals, an automatic sprinkler system will actually, in most cases, use less water. It will also disperse the water at an even rate, and for a predetermined amount of time. This allows you to water sunny and shady areas for different periods of time, and to water when it is most efficient. One obvious benefit is the ability to continue a watering program while you are away on vacation.

Q:  Will the installation make a mess of my lawn?

A:  Controlled Irrigation installation techniques have made system installation far less disruptive than in the past. Controlled Irrigation removes existing sod from ditch area. Then machine digs or hand digs the trenches. In general, the nicer the lawn to begin with, the less mess there is. In this case, all of the sod is still there, sod just need to be put back and tamped. A lawn that is in disrepair will be hard to make look good, as there is no sod to be replaced. In this situation, overseeding and new growth will be made easier because of the sprinkler system.

Q:  How long does a system take to put in?

A:  It would depend on the area that is trying to be covered. An average size lawn (@15,000 sq. ft.) can usually be done in one full day, depending on the situation. A large lawn can take anywhere from two to four days. On average, we spend two days on a job.

Q:  What type of maintenance does the system require?

A:  All systems need to be down in winter. In the Treasure Coast Climate we recommend leaving them on during the winter. Controlled Irrigation ensures that you have less problems when you start back in spring time Most people that we install systems for simply turn it back on in the springtime themselves. We do offer the service of opening systems for the season. The quality of the products used initially, and of the overall installation, play an important part in the long term service of the system. The better the products and installation,

the less trouble you should expect in the future. Controlled Irrigation uses the finest products available in the industry, and strives to provide the finest installations in the business.

Q:  What products do you use?

A: Controlled Irrigation uses what we consider to be the finest products in the industry, which is why we don't use just one particular companies products, but a variety of brands we trust.

Q:  What about underground wires and/or electric dog fences?

A:  Before the first shovel hits the ground we contact a Locate Company  that flags for sewer, water,  electric, phone and cable lines. Any wiring outside of the above listed items such as dog fences, post lighting, etc. is the homeowner's responsibility to mark.

Q:  What happens when it rains?

A:  Controlled Irrigation installs a rain sensor on every system we install. This device senses rainfall and will shut down your system when it has received enough rain. The sensor is adjustable, so it can be set to individual needs and preferences.

Q:  How long and how often should I run my sprinkler system?

A:  While there are no set parameters for this, here are a few rules of thumb. The precipitation rates on geardrive/sprayhead zones is about a 4 to 1 ratio. This means that gear drive zones should be run at four times longer than sprayzones. Gear drive zones should be run for a minimum of 30 minutes, except in very shady areas. In the hot parts of the summer, these should be changed to 45 minutes, even an hour. Sprayhead zones should be run for 8 to 10 minutes and bumped up to 15 to 20 minutes in dramatically hot weather. In the spring and fall, you should be able to get by with every second or third day. When the weather gets very hot, once a day is a good idea as this will keep the lawn from getting stressed. Time and experience will tell you what will work best on your own property.

Q:  What is a backflow device, and why do I need one on my sprinkler system?

A:  A backflow device is generally a brass assembly that will prevent any water from the sprinkler system from getting into the drinking water supply, and are required by all municipalities. There are many different types of these, and each individual municipality has differing requirements for the installation. Controlled Irrigation is very familiar with most locales, and can provide the appropriate backflow device for your system.

Q:  What does "Head to Head" coverage mean, and can I get by without it?

A: On any system, one of the fundamentals of design is that each head hit the one to the left and right of it, and any other heads within its throw. This provides even water coverage, referred to as "Matched Precipitation." Really what you are trying to achieve is artificial rainfall. Areas with only single coverage might fare well in cool conditions, but will be the first to brown up in very hot weather. You are far better off to design and install the system properly to begin with, as it is much harder and expensive after the fact to add or move heads to compensate for dry areas. You can always run zones with single coverage heads longer, but now you are over-watering the double/triple coverage areas to compensate for the single coverage areas. Head to head coverage is paramount for a lush, green lawn.

Q:  Will water alone keep my lawn that deep green color?

A. Having a sprinkler system installed is the first step towards a healthy, green lawn, but it is not the only answer. Fertilization is generally required for that lush green look, as is bug control. We get calls a lot in the summer from people that think there is something wrong with their sprinkler system, but upon inspection, there are bugs destroying the lawn, or they have not used any fertilizer. If you are unfamiliar with fertilizer and pesticides, we recommend that  you contact a company in that business to look after your lawn. Having a sprinkler system installed is the first step towards a healthy, green lawn, but it is not the only step.

Q:  What is the difference between gear drive heads, and sprayheads?

A:  Gear drive heads have a water powered motor that makes the upper part of the head rotate. These heads are used for large turf areas, with throws of 15 to 35 feet. They are adjustable not only in the precipitation rate, but the arc as well. Controlled Irrigation uses only the finest gear drive heads, which are easily changed from 40 degrees, to a full 360 degree rotation. Sprayheads are generally used for smaller or oddly shaped turf areas. Sprayheads have no moving parts, and emit a spray of a particular pattern. The nozzles are interchangeable, and come in circular, rectangular, and square patterns, with throws of four to fifteen feet. The precipitation rates of these two types of heads are dramatically different, and should never be mixed on the same zone.

Q:  Why should I choose Controlled Irrigation to install my system?

A:  Controlled Irrigation has a reputation for doing the best work in the business. We pay attention to the small details, and take great pride in each and every system we install. At Controlled Irrigation, quality is our standard, not our goal.
