It is no secret that maintenance of any automated system or machine is an essential part of the upkeep to run anything efficiently and cost-effective.

 

Our certified technician will fully inspect your system from start to end and everything in between. All components will be verified and adjusted to bring you optimal use of your water while maintaining the desired look of your lawn.

 

Sprinkler heads, nozzles, control valves, pipes and wires can break down due to manmade or environmental reasons. Our expert sprinkler repair service is here to assist you.

 

An essential part of our maintenance and tuning service is the sprinkler itself. Sprinkler heads tend to have the most wear and tear out of the system. It is therefore of extreme importance to verify that the head and its components are working and are not worn or worse leaky. We inspect everything and provide the tune-up your system needs.

REPAIR / MAINTENANCE

n means to turn the valve on manually and not by way of the timer, so if you are turning your sprinkler system on in the spring they should all be off and use the irrigation timer to turn them on.

During a fall blowout, your irrigation professional will turn the solenoids to the on position to open the control valves manually.  This way they do not need to use your irrigation timer.  When they are done, they should move the solenoids back to the off position.

Care should be taken not to overtighten the solenoids.  These are made of plastic and overtightening them may cause them to warp.

 

The tips listed below are based on an irrigation system installed by us in Calgary, Alberta.  Not all irrigation systems are the same and different climates require different types of underground sprinkler installations.  For example, some warmer areas have an external water meter in the lawn.

 

  1. Start on the outside of the house and find the mainline(s) to the irrigation system. Make sure that everything outside is closed tight, including solenoids, bleed screws, hose bibs, and ball valves.  Once everything outside has been secured, located the mainline inside the house.

  2. Locate your main water shut-off for the house. Ensure it is on all the way.  Sometimes this can be partially closed and that will restrict the water flow to your irrigation system. Downstream of the main water shut-off, you should see a water meter.  Usually just downstream of the water meter you will find the isolation valve for the irrigation line, along with a cross connection device – usually a Double Check Valve Assembly.  It is very important that the DCVA must be tested yearly prior to turning on the underground sprinkler system.  If you have an older irrigation system, you may not have a DCVA. We highly recommend that you have a testable DCVA installed, in accordance with Calgary bylaws and national plumbing code.

  3. Check the mainline inside for any drains. These may be boiler drains or ball valves with nothing connected to them.  Make sure that they are closed tight.

  4. Once it has been confirmed that everything has been closed tight inside and out, you are good to turn the water on to the sprinkler systems. Please note the water should be turned on slowly to prevent water hammer.

  5. Listen carefully to the water and the vibration of the line, as everything should be closed outside. Once the line is fully pressurized the water will stop.  If the water is still running after 20 seconds, it is a good idea to shut it off and look for leaks inside and outside the house.

  6. If the water seems to have stopped running, take a look at the water meter to double-check. If it is still turning, you may yet have a leak in your irrigation system or a tap in the house may be open. To tell these possibilities apart, turn off the water to the sprinkler system.  If the wheel stops turning then you know it is an issue with your sprinkler system.  If it keeps turning it is reasonable to assume it is a running faucet, washing machine, humidifier, etc.  Best practice would be to find out what is going and shut it off so that you can see the meter stop turning.

  7. Now that you know that all is ok, you can go outside and turn on the external valves and charge the irrigation system outside. Do this slowly to prevent water hammer. Again, if you still hear water flowing after 20 seconds, turn off the water and look for leaks.  Once the water stops flowing, open the external isolation valve open all the way.

  8. Key point: if any of the ball valves are not open all the way, it will affect your irrigation system’s performance. We cannot emphasize enough that you must ensure your water meter is not turning and to ensure all water valves are all the way open, including the main water supply for the house.

  9. Once you have verified that everything is open and there are no leaks, you can turn on each zone manually using the solenoid or bleed screw, or you can use your timer to test each zone to ensure there are no leaks or defective sprinkler heads. If you notice any issues, document them and move onto the next zone.

  10. Once you have verified that there are no issues, you are ok to set your irrigation timer. Your best practice is to test each zone by way of the timer, even if you have already tested them manually. This way, you can ensure that all of the solenoids are working properly.  Find your irrigation timer manual by searching it online and ensure it is set correctly.

  11. Pro tip: if you are turning your sprinkler system on in the spring, you may not need to run it as often. Cut back the days and/or have a smart Wi-Fi timer that adjusts your irrigation run times automatically based on local weather. We recommend the Hunter Hydrawise Wi-Fi timer.

Find the valve’s solenoid.  That is a cylinder with the wires attached to it.  Slowly turn it to the on direction (counter-clockwise) a quarter turn at a time until water can be heard flowing through the valve. To shut it off, turn the solenoid in the off direction (clockwise).  Do not over tighten.

 

Note: If you turn it too many times it may become unthreaded from the valve.  If that happens, it is a good idea to shut off the water to the sprinkler system and thread it back in.  Be careful, as these are plastic fittings and can be easily cross threaded.

  1. Find your water meter and ensure it is not turning.

  2. Go to your irrigation timer and turn on a zone, then look at your water meter. If the water meter is turning you know there is water going to that zone.  You can repeat for all zones to ensure they are all working.

  3. After you have confirmed that the irrigation system is working electronically via the timer, you can then turn on each zone and check to ensure the zone is functioning properly.

It all depends on weather.  In Calgary, Alberta we typically start turning on sprinkler systems the first Monday in May.  We do tell clients that they should have their irrigation system up and running by the Victoria Day Long Weekend.
