As long as the threat of frost has passed, you can open your sprinkler system. We generally recommend opening a sprinkler system no earlier than April 15; although you can wait a little longer if the spring is rainy. The good news is that as long as your sprinkler system was installed properly, opening your sprinkler system will be a breeze.
Let’s get started.
1. The manual valve drain should be closed. This valve is located below or before the backflow device outside your home.
2. Open the gate valve slowly. This valve is positioned after the meter in the basement on the line going out of the house to the backflow device.
3. Check the main line, valves and backflow device to make sure there are no leaks.
4. Open the front cover of your sprinkler timer and locate the battery backup. Replace this according to the instructions in your manual. Check each zone one at a time to make sure that there are no leaks or breaks.
5. If there is excess lawn or plant growth near the sprinkler heads, remove this so that the sprinkler can operate efficiently.
6. Also make sure that the sprinkler heads are even with the grade of the lawn so that they do not get hit with the lawn mower or any other types of lawn equipment.
7. All sprinkler heads should be at least one-inch away from walks and curbsides.
8. The sprinkler heads should be adjusted properly to cover each zone. If the heads are off, you can use basic tools or your hands to adjust them.
9. The sprinkler heads should be clear, so check them for clogs. If you notice a clog, simply remove the head casing or nozzle and clean out the filter with air or water. The most common clogs come from stones or other debris lodged in the nozzle.
10. It’s possible that there may be a problem with a particular zone only. If this is the case, turn the timer off on that zone. This way, the system can operate correctly while giving the zone rest. Contact an irrigation professional for further assistance.
