If you own a garden, summer is the best time to spend pleasant evenings outdoors with your family and friends. To keep the garden always green and luxuriant, the best system is to have an adequate irrigation system. But how do you clean your garden sprinklers to keep them running at all times?
The first thing to do, before moving on to the actual cleaning, is to remove leaves and any weeds that may have appeared around the head of the dispenser, to prevent them from infiltrating the system!
Check-up of the irrigation system
To carry out the maintenance of the irrigation system, it is necessary to start from simple control operations to ensure that the sprinklers, control unit and solenoid valves work correctly.
If possible, carry out these operations on sunny days and not after a rainy day, in order to avoid mud entering the system while disassembling or reassembling it.
Irrigation control unit
This element is generally found in the home, protected from the elements. The checks we have to make are first of all the state of charge of the buffer batteries, which store the programming data. If the batteries are not charged, they must be replaced to ensure that the system operates throughout the summer. Then check the configuration of the date and time. Finally, check and clean if necessary the rain sensor, which interrupts irrigation in case of bad weather and precipitation.
Cleaning the sprinklers
This is certainly the most complex operation. There are two types of sprinklers:
- Spray heads
How to clean your garden sprinklers: DIY maintenanceTo clean your sprinklers, unscrew the base and check for soil, pebbles or limescale, especially in the outlets of the spray. Clean any accumulation of dust or dirt with a gentle brush. In case of limescale, use the WD-40 Multifunction with the precision straw to remove it. Then loosen the small adjusting screw and spray a small amount of product here too, which also has lubricating and protective properties against rust and oxidation.
Now clean the central body, unscrewing and cleaning the piston with running water. In case of limescale, always use the WD-40 Multifunction to remove it.
If filters and piston are damaged, proceed with their replacement.
For rotors, the mechanism must be removed by removing the spring. Now clean the internal filter thoroughly. Then we remove the head that regulates the water jet and apply WD-40 Multifunction on the small screw to protect it from oxidation, which would make it impossible in the future to replace the head if necessary. Unlike static sprinklers, rotors have an internal water-driven turbine. If the rotor no longer rotates, the filter at the base must be cleaned.
Before repositioning the sprinklers on the same WD-40 Specialist silicone lubricant to ensure the smoothness of the pop-ups. Take care to position the spray exactly as it was before cleaning.
Checking the solenoid valves
After removing the protective cover, we operate the control unit to check the operation of the solenoid valves one by one. We check that they open and close correctly and above all completely, without letting the water escape.
As you can see, cleaning the garden sprinklers is an uncomplicated and time-saving operation.
Once all the operations have been completed, thanks to the precious help of the WD-40 products, we can operate them and enjoy our lush lawn without any worries!
