Starting the Sprinkler System in the Spring

When spring time comes around, many home owners call their local landscaping company to come out and perform a sprinkler start up. It is possible to do it yourself but be sure to calculate your moves because it isn’t as easy as just turning a knob.

First, be sure the big spring thaw has happened in your area. It is not a good idea to introduce water to the irrigation system if another freeze could happen.

Make sure that the drain valve is closed. This manual valve is normally found under the vacuum breaker (back-flow assembly) located on the outside your home. Make sure the knobs on the vacuum breaker are also closed.

Find the main water valve that is normally found in the basement near where the vacuum breaker is located on the other side of the wall. Once you find this valve, slowly turn it open.

Since all valves on the outside of the house are closed, the water should stop running quickly, check for leaks.

Go outside and check for leaks, then slowly open the first knob/valve closest to the wall of the house (feeding into the vacuum breaker). This should fill up the back-flow assembly. Then open up the second valve feeding into the irrigation system. It will take a while to charge this up with water.

Replace the battery in your sprinkler timer if needed. Use the sprinkler timer to manually check each zone. Go through each watering zone and check each sprinkler head and look for leaks.

Make sure each sprinkler head is clear of vegetation that would obstruct the watering of your lawn. When they are off, these sprinkler heads should be level with the lawn so mowers don’t chew them up.

Adjustment to the heads of each sprinkler may be needed to ensure each one is targeting its zone accurately. A screw driver can be used to make tweaks.

If a zone seems to be getting watered improperly, use the sprinkler timer to turn that individual zone off and contact your local sprinkler guy.

Continue to occasionally check your zones for proper water coverage. Usually a dry spot in the yard will appear if the sprinklers are not fine tuned.

If you are experiencing problems with your sprinkler system start up and live on the front range of Colorado give Green Guys a call for help.
