This is my second sprinkler system from Green Valley. I called for a quote and they came out the same day. The system was installed and working the next day. Green Valley is prompt, professional, courteous and very reasonable. Excellent after sales service. Other family members used Green Valley as well. I would definitely recommend them.
I was impressed with the level of customer service from the moment I called Green Valley Irrigation. John, the owner, not only returned my call the same day, but he also came by my house to provide a quote in a timely manner. He was extremely accommodating and professional. Once I decided to get the sprinkler system installed, John spent time to thoroughly go over it with me and answer all of my questions. He explained the warranty and encouraged me to call if I had any further questions or concerns. Several weeks after the sprinkler system was installed, I had some landscaping work completed. One of the sprinkler lines was accidentally damaged. As soon as I called Green Valley Irrigation, John came back to my house and repaired the damaged line at no cost. I have recommended this company to several family and friends and they have all been satisfied with the price and the level of work. You will not be disappointed if you decide to use Green Valley Irrigation.
John installed our in-ground sprinkler system back in 2003 when we bought our house and since then has been providing spring and fall maintenance as well as occasional repairs which were all covered under his maintenance agreement. I’m really happy with his service and have recommended him to several of my friends and family.
I have been extremely pleased with the installation and maintenance of my sprinkler system. My lawn looks great and has been low maintenance for me. I have had the system to 2 years now and am very pleased. John has been very professional and responsive right from the initial quote to installation to service. I have referred Green Valley Irrigation to many of my family and friends.
I was referred to Green Valley Irrigation Ltd to have our irrigation system installed. I dealt with John from beginning to end of this project and he has done a fantastic job. He has been very helpful explaining the system and giving me full details of what they were planning to do. I have already referred John to my family and friends. John is a very efficient and knowledgeable person to deal with as well as his crew.
I purchased a house with a irrigation system that was already installed. Soon after I noted several areas that were not adequately irrigated. John was able to fix the problems. He has always been prompt, reasonable, reliable and very courteous. I would highly recommend his services. He has also installed drippers for the flower beds that were professionally installed and well hidden. I will continue to use him in the future.

We make sure all the steps are taken to perform the service at the your convenience.
Here are several key characteristics to look for when evaluating the water efficiency of a lawn sprinkler system:
Matched-Precipitation Rate Sprinkler Heads
All sprinkler heads on a given circuit should be the same type (e.g. rotors, pop-up spray, etc.) and have matched precipitation rate (in inches per hour). Heads with differing precipitation rates have widely varying operating times, which can lead to the over-watering of one area in order to sufficiently water another.
sprinkler installation Turf pop-up sprinkler systems are designed to operate with head-to-head coverage, where the spray from one sprinkler head reaches to the next, resulting in necessary overlap. Precipitation rates are based on the assumption of overlap. Places where the sprinkler's spray pattern does not overlap are likely not getting sufficient water and may develop brown dry spots. These spots indicate the system has low "uniformity" of coverage. To compensate, one has to run the sprinklers for longer times to get adequate water to the dry spots, while the rest of the lawn is getting over-watered.
Precipitation Rate That Does Not Exceed the Soil's Infiltration Rate
Based upon soil characteristics, water will soak into the ground at differing rates. Sandy soils have high (fast) infiltration rates, while clay soils have low (slow) infiltration rates. If the precipitation rate of the sprinkler heads exceeds the soil's infiltration rate, then runoff and erosion occur (especially on slopes). On flat ground, this will also lead to piddling. If your sprinklers' precipitation rate exceeds the infiltration rate, lower precipitation rate heads can be installed, or you can shorten your watering times and use multiple start times (e.g. 3 start times at 5 minutes each at 1-hour intervals instead of 15 minutes all at once) to allow the water to soak into the soil.
Appropriate Water Pressure
Each sprinkler head is designed to operate within a certain range of pressure, typically around 40 to 50 pounds per square inch (PSI). When water pressure is too low, the sprinkler head will emit large drops and likely will not produce the proper spray pattern or a radius that reaches to the next head. If pressure is too high, the head will produce a fine mist, which leads to water loss due to evaporation and "fly-away" in even light winds. In addition, high pressure can lead to over spray and a distorted spray pattern, along with many other problems.
Clean, Even Spray Pattern
If the spray pattern of a head is distorted, browns spots may develop on the lawn. This may be caused by blockage in the screen or in the nozzle itself, and the head may need to be cleaned. If this does not fix the problem, the nozzle may be worn and needs to be replaced.
There should be no wasteful over spray onto sidewalk, patio, driveway or street. If there is over spray, replace the nozzle with another with the appropriate spray pattern (e.g. 1800 instead of 3600) or relocate the sprinkler head.
Vegetation or other objects should not obstruct the spray from the head. Trim back vegetation or raise the sprinkler heads as needed. This will increase the system's uniformity of coverage.
