Be prepared for the summer season.

Irrigation Spring Start Ups

Winter in Calgary is harsh, the ground freezes, shifts, thaws, then refreezes multiple times from October to April. 


During these freeze thaw cycles, irrigation components are put under stress and need to be inspected in spring for proper summer operation.


Spring in Calgary is about six weeks long, summer about ten weeks long.  One week it is snowing, next it is dry, then raining, then scorching dry and hot and suddenly the irrigation system must run well.


Don’t waste time fighting with your underground sprinkler system. Have Next Rain help you turn on your sprinkler system with ease.


Our irrigation technicians are ready to make necessary repairs and willing to answer your questions, provide improvement suggestions, help teach you how to use the controller / timer and get your underground sprinkler system ready for summer.


Make sure your grass, plants and trees get the adequate water they need to survive the dry summer conditions in Calgary.


If irrigation repairs are necessary, the service vans are fully stocked and any changes can generally be made on the spot.

Yes. To do a proper job, we need access to the inside of the house.

Each system is very personal, we want you to be satisfied and the best way is to be home, talking with the technician, asking questions, pointing out items of importance.

Our experience tells us communication breakdowns are higher in cases where the decision maker cannot be present, and leads to frustration with all parties involved.


Of course, please however follow our procedure below “How do I turn on my own sprinklers?”.  If you have questions, call our office for help.  403-613-0552

Please DO NOT turn the water ON and set the controller to run with out doing a system check thru.  

It takes about 45 minutes to turn on and test / check thru a smaller residential property in Calgary. 

A lot of our customers have us perform this as “There is always something broken” or small parts worn out – most are minor but annoying to track down and repair yourself.

We recommend waiting until around May 1st for starting up your sprinkler system in Calgary. Starting  up the system too soon will result in certain parts not functioning correctly, generally causing the water  to leak thru the control valves and water leaking out of the sprinklers or zone refusing to shut down. If  this occurs, turn the system off and wait a few more days.  

If you would like us to complete this procedure for you, please contact our office at 403-613-0552.  This procedure usually takes about 25 – 50 minutes for a typical yard.  

Step 1) Make sure the yard is visibly clear of snow and ice. Find a small probe or a 20cm / 8” screw  driver and test the ground on the north side of the property. Usually on the north side of the property is  where ice and ground thaws out last in Calgary. Probe the ground for frost. If you can not get the probe  easily into the ground, wait until the ground softens up.  

Step 2) Open the valve boxes (usually green in colour).  

  1. a) Is there ice in the box? If there is, leave the lid off the box and wait until the ice & water have  melted and drained from the box.  
  2. b) Are the bleed screws tight and solenoids in the off / closed position?  
  3. c) Is there any broken pipes or parts?  

Step 3) Check for any open hose connections, taps or drain valves on the irrigation mainline. Most  houses have a hose hook up connected to the irrigation system on the mainline outside where the water  exits the house.  

Step 4) Make sure all inside valves are closed.  

Step 5) SLOWLY open the inside mainline isolation valve. Do this very slowly. Water should stop  flowing in a couple minutes. If not, turn the water off to the irrigation system and walk property and  look for signs of water.  

Step 6) For automatic systems, set each zone to run for a 2-3 minute test cycle. Check all zone  components by walking the system with the zone running automatically. Make sure sprinklers are  rotating and spray sprinklers properly covering.  

Step 7) For manual systems, turn on each valve manually and check each zone.  

Step 8) Once all zones have been checked thru, return to the basement of the house and check the water  meter. With no water in the house running and the sprinklers off, the water meter should not be moving.  

Step 9) Program the irrigation controller / time to water. Water schedule should be updated at minimum  monthly during the watering season. New model WiFi controllers connect to the internet and  automatically adjust the controller based on the weather, thus matching the water requirements to the  local weather. We generally set sprinkler controllers to water grass a maximum of 2 – 3 times a week,  unless daytime temperature is over 28C. Watering too often shortens the grasses root zone and weakens  the grass, making the grass susceptible to winter kill, rodents, weeds, stress & washes away the fertilizer.  

** If temperatures drop below zero, we recommend shutting the water off to the sprinkler system and  opening any drain valves. Then once the weather warms, repeat this procedure again.  

Remember to winterize the system before freezing temperatures occur in fall!  – We recommend by the end of September.
