Maintenance of irrigation system 

We provide various services for keeping your  irrigation system to work efficiency, such equipment are like : irrigation controllers , filters , rain sensors , water pump systems and control panels , solenoid valves , solar powered items , rain water harvest tanks .
Some check points are:

a. keeping the rainwater harvesting tanks : FRP or concrete in acceptable condition

b. keeping the pH of your tank water in acceptable range

c. keeping your drip lines and spay equipment in conditions meant to do the job

d. replacing and modifying your system 

e. rectifying faulty green wall and landscape irrigation systems

Maintenance the key to landscape irrigation efficiency 

Regularly checking and maintaining landscape irrigation systems is an effective and low-cost way to ensure that they continue to operate efficiently. This will help with water use efficiency, reduce pollution from run-off and over-irrigation and support healthy plants by ensuring they receive the right amount of water at the right time and in the right place. 

It is a good idea to check a landscape system at least twice a season-once at the beginning of the season when the system is first turned on and again halfway through the season. 

The first thing to do is to inspect the controller and make sure it is in and functioning If necessary, update the time and date and check the plugged connection on all wires. Make sure that rain, wind, or soil moisture sensors are connected. Finally, replace the back-up battery, change the schedule to reflect the current season and irrigation needs of the landscape and then turn on each zone and look for system damage. 

WHAT CAN GO WRONG 

Lots of things can go wrong with a system, especially when it has not been operated for a while. Check for things such as leaks, clogged nozzles and damaged heads. 

Leaking valves or pipes. Leaks can occur because of weather damage (freezing and thawing), mechanical damage (from shovels and other sharp tools), vandalism and normal ageing of the system. While some leaks from valves and pipes might be large and easy to see, smaller leaks might be harder to find. Replace or repair damaged valves and pipes 

Broken or missing heads. Sprinkler heads be damaged by lawn mowers, vandalism, and from improperly installed heads and normal wear and tear Check all heads and replace any that are damaged or missing.

Clogged nozzles. Nozzles can be clogged by debris entering the irrigation system, a dirty water source and normal wear and tear. To unclog nozzles, flush system at the beginning of the irrigation system. It is a good idea to install screens on sprinkler heads, replace clogged nozzles and improve system filtration.

Seal leaks. Over time, dirt and debris can wear out the wiper seal resulting in leaks around the top of the spray head. Ifthe spray head is a single unit, then replace the entire head; with some spray heads it is possible of the sprinkler head and replace it. 

Sunken heads. It is not uncommon for sprinkler heads to settle into the soil over time. Grass clippings, soil, and other debris can build up around heads so that they don't clear the grass adequately, which disrupts the spray pattern. With higher mowing heights with older systems designed for shorter turf. Heads can be raised by using taller sprinkler bodies or by installing solution but this must be done regularly pri and rep dirt  to screw off the top being recommended, there could be an issue now risers. Cutting turf away from heads is another solution but this must be done regularly 

Tilted heads. Lawn mowers and wet soil can cause newly installed sprinkler heads to tilt resulting in uneven coverage. If possible, install the sprinkler on swing pipe and move the head out of the line of mowers other equipment that may cause the head to settle or shift. Otherwise, reposition the head and pack the soil around it carefully.

IS THE SYSTEM OPERATING EFFICIENTLY? 

A number things Misaligned heads. Misaligned heads result in overwatering parts of the landscape and brown spots in other areas. manufacturer's instructions can affect the efficient Realign heads according to manufacturer's instructions. 

Overspray (runoff) It is something we often see when walking around cities sprinklers watering the footpath as well as grassed areas because of everspray Overspray can result p0or distribution uniformity, overwatering and runotfon hardscapes Reduce or eliminate overspray by adjusting system pressure and adjusting nozzles or by installing the proper size and type of nozzle. 

Pressure problems. High pressure causes problems such as misting from spray heads and rapid rotation of impact rotors resulting in poor coverage and potential damage to the irrigation system. Installing or adjusting a pressure regulator or installing pressure regulating heads can eliminate the problem. 

If heads fail pop-up orrotate, this is often symptom of low water pressure. This can also result in poor coverage and dry spots in the landscape. Adding a booster pump, watering during off-peak times or reducing the number of heads a zone can increase pressure. Incorrect spray arc. Check the spray pattern of the sprinkler heads on cach zone and adjust it if necessary and ifit is possible. To do this you might have to replace the nozzle with one that has the correct spray pattern. Older systems especially may need to be updated with different nozzles more suited to the area being irrigated .

THE BOTTOM LINE 

Irrigation maintenance is one of the most important factors in reducing water waste in the landscape A well-maintained and properly adjusted system is essential for a healthy, beautiful, Spending time maintenance a couple of times a season will ensure that used efficiently the irrigated
