One of the biggest benefits our clients mention is the fact that we are a local family business and the owner is involved directly with every sprinkler install.”We make sure your sprinkler system installation is done right the first time.” Why do so many people trust Dallas Landscape and Irrigation Inc.? We provide exceptional value in the products and services we provide. Most of our customers consider us to be the “safe” choice due to our reputation, experience, quality, and long-term service we provide. We only install the best quality products (we personally visit the manufacturers), and our lead installer has been with us from the start.

Certainly there is a price to pay for quality and service, but we keep our overhead low, run an efficient business, and always feel we are priced competitively. In fact, nearly 75% of our service division calls are to “third-party” systems where the company that installed the package is not in business anymore, or does not respond to requests made by their customer. Every year – we will get calls from people that “saved” a few hundred dollars on their sprinkler system installation, only to find out later that it was not designed or installed properly, nor does the company stand behind its work. Eventually and almost always – their loss is our gain!

serve our customers.
FAQ 1) I think I have a leak in my irrigation system. How can I be sure?
The easiest way to determine if there is an active leak in the irrigation system is to use the water meter as a guage. Water meters are equipped with a microdial that measures minute amounts of water flowing through the meter. This microdial is often shaped as a triangle or a star. If no water in the home is running (no leaking toilets, etc.) the microdial should be stationary. However, if the microdial is moving and no water is running in the house, you can shut the water off at the backflow preventer valve and recheck the microdial. If the movement of the microdial ceases, then we can assume that there is an active leak in the irrigation and you should have it serviced. If there is still movement of the microdial after cutting the water supply at the backflow preventer valve then there is a leak elsewhere in the water line, but not involving the irrigation system.
FAQ 2) How can I adjust my Rotors and Sprays?
Rotors are sprinkler heads that rotate from side to side as they operate and are generally used for large turf areas. Sprays are smaller sprinkler heads that are stationary when active and are generally used for flower beds and small turf areas. Rotors need to be adjusted using a special plastic key (Hunter brand) or small slotted screwdriver (RainBird brand).
Instructions for RainBird rotary heads can be found at:
Backflow Testing Frequently Asked Questions
FAQ 1) Why do I need my “Backflow Prevention Assembly” tested annually?
Backflow Prevention Assemblies and Devices break or wear out in about 7 years, just like the parts of a car. Backflow is the hydraulic condition that can cause an RP or Double Check Valve to stop working in the described normal flow pattern.
FAQ 2) What is a Backflow preventer?
A Backflow preventer is a means of mechanism to prevent Backflow. The basic means of preventing Backflow is an air gap, which either eliminated a cross-connection or provides a barrier to Backflow.
FAQ 3) What is a reduced principle (RP) assembly?
An RP is a mechanical Backflow preventer that consists of two independently acting, spring-loaded check valves with a hydraulically operating, mechanically independent, spring-loaded pressure differential relief valve between the check valves and below the first check valve.
FAQ 4) What is Backsiphonage?
Backsiphonage is a condition that causes a sub-atmospheric pressure to be applied to the upstream side of the assembly.
FAQ 5) What is an air gap?
An air gap is a vertical, physical separation between the end of a water supply outlet and the flood-level rim of a receiving vessel.
FAQ 6) What is a double check valve assembly DCVA?
A DCVA is a mechanical Backflow preventer that consists of two independently acting, spring-loaded check valves. It includes shutoff valves at each end of the assembly and is equipped with test cocks. A DC is effective against back pressure Backflow and backsiphonage but should be used to isolate only non- health hazards.
Question and Answer Section:
Q: Do you charge to give estimates on new installs?
A: No. We will meet, email or call you and provide a professional bid for no cost for tree service, drainage systems , new sprinkler installations or rain gutters.
Q: Will you install a landscape if I don’t have plans?
A: We prefer to have plans to bid off of and to follow off of when we work. There are exceptions and we can do a design build based on the owners thoughts and ideas or the look they are going for. We use this information to design the look you desire.
Q: Sunlight, the air we breathe and the water we drink are all natural resources. Unlike the past, water has become a resource we pay for. Why is that?
A: Although water is provided by nature for free, because of pollution and changing weather patterns, it has become difficult to get usable clean water running from our taps. We are increasing aware of this effect in our pocketbooks. Mother Nature is slowly but surely getting drained from this valuable resource. Although most of the earth’s surface is covered with it, only 2.5% is fresh water and only 1% is drinkable the other is locked up in the polar ice caps. Some parts of the earth have low rainfall figures, while other parts of the world regard a raincoat to be compulsory. People who live in high rainfall climates easily disregard the scarceness of water. Over 1 Billion people lack the appropriate drinking water. Evapotranspiration accounts for 4,000 gal water per day in one acre of corn. Some of our aquifers that supply our ground water have dropped 30-40 ft and only 1 in 5 will still contain water in the year 2020. Whether or not you have a lot of water, there are some guidelines we can follow to save water. Not only will it save us some money, but it will also help preserve this precious resource provided by nature.
Here are some of the guidelines to follow in order to save a drop or two:
1) Plant flowers that require less water. Herbs are good examples of plants that require less water. They are also useful for cooking and some of them even have medicinal uses.
2) Water the garden at times when the temperature is lower. Early in the morning for instance. During the day water will evaporate at a higher rate because of the higher temperature.
3) Service taps regularly. In the long run your savings on the water bill will be remarkably more than the service cost of taps. A dripping tap not only waste money and water. If it is located close to the house or other structures, it will cause damage to the foundation and surrounding structures. Damp conditions will result in expensive and timely repair work to your house.
4) Buy a cover for your pool. By doing this, the water surface will not be exposed to direct sunlight.
Tips on saving water
- Avoid over-watering lawns and gardens. Surface runoff and water that is applied to areas that have no roots or grass are completely wasted.
- Watering early in the morning minimizes fungal diseases on the leaves of plants, and minimizes evaporation.
- Separating shrub garden, annual garden, grass, and hanging baskets/pots into separate zones can allow more specific watering schedules tailored to each specific area, minimizing over and under watering.
- Trim grass at a higher mower setting to shade roots from sunlight and encourage deeper roots.
- Mulching Landscape Beds
