Bonus Questions
Can starting up my sprinkler system too late in the season affect my lawn or garden?
Answer: Yes, starting up your sprinkler system too late in the season can definitely affect your lawn and garden in a few ways:
- Stress on plants: Lawns and gardens entering a dry period are already stressed. Delaying watering further increases this stress, making them more susceptible to disease and insect damage.
- Shallow root growth: Without consistent watering, plants tend to develop shallow root systems to access any available moisture near the surface. When deeper watering finally arrives, it may not penetrate deep enough to reach these shallow roots, leaving them parched.
- Uneven watering: If the soil is very dry, the initial watering may not penetrate deeply and evenly. This can lead to patchy areas where some parts of the lawn or garden receive enough water while others remain dry.
- Increased weed growth: Dry conditions favor weeds that can thrive in harsh environments. Delaying watering can give weeds a competitive advantage over your desired plants.
However, the severity of the impact depends on several factors:
- Climate: In areas with mild climates and consistent rainfall, delaying watering may not be as detrimental. However, in hot and dry climates, even a short delay can have a significant impact.
- Soil type: Sandy soils dry out faster than clay soils. So, if you have sandy soil, even a short delay in watering can be critical.
- Plant types: Plants with deeper root systems are generally more tolerant of dry spells than those with shallow roots.
Are there any precautions I should take before starting up my sprinkler system?
Answer: Absolutely! Here are some precautions to take before starting up your sprinkler system for the season:
General System Check:
- Inspect for Leaks: Turn on the water supply to your sprinkler system slowly and check for leaks around the shut-off valve, pipes, and sprinkler heads. Repair any leaks promptly to avoid water waste and potential damage.
- Check for Damage: Look for any physical damage to pipes, fittings, or sprinkler heads that may have occurred during winter. Replace any cracked, broken, or malfunctioning components.
- Sprinkler Head Maintenance:
- Clean Clogged Heads: Sprinkler heads can become clogged with debris over time. Clean each head thoroughly to ensure proper water flow and spray patterns.
- Adjust Heads: Inspect the spray patterns of each sprinkler head and adjust them as needed to ensure even coverage and avoid watering sidewalks or driveways.
- Check for Broken Heads: Replace any broken or malfunctioning sprinkler heads to maintain proper water distribution.
Winterization Check (if applicable):
- Ensure Proper Drainage: If your system was winterized by blowing out the lines with compressed air, verify that all the water has been removed to prevent pipe bursts when you turn the water back on.
Safety Precautions:
- Call Before You Dig: If you plan on digging anywhere near your sprinkler system to make repairs or adjustments, call your local utility locating service a few days before to mark any underground lines to avoid accidentally hitting them.

Are there any steps I need to take to prime my irrigation pump before starting up my sprinkler system?
Answer: Yes, priming your irrigation pump before starting your sprinkler system is an important step to ensure it functions properly. Here’s why:
- Air in the System: During winterization or periods of inactivity, air can enter the pump and pipes. Air pockets can prevent the pump from drawing water efficiently and could lead to overheating or even damage.
- Improved Performance: Priming fills the pump and pipes with water, removing air pockets and allowing the pump to operate smoothly and efficiently.
Whether you need to prime your pump depends on a few factors:
- Winterization Method: If your system was winterized by simply draining the water, priming is likely necessary. However, if it was winterized by blowing out the lines with compressed air, priming might not be needed as most of the water would have been removed.
- Pump Type: Some self-priming pumps can automatically remove air pockets. Consult your pump’s manual to see if priming is necessary.
Here’s a general process for priming your irrigation pump (consult your specific pump manual for detailed instructions):
- Locate the Prime Plug: Most pumps have a designated “prime plug” or “fill port”. It’s usually a small threaded opening on the pump housing near the water inlet.
- Turn Off Power: Before starting any work on the pump, ensure the power supply is turned off for safety reasons.
- Prepare Water Source: Have a bucket of clean water or a hose readily available to fill the pump.
- Remove Prime Plug: Using a wrench, carefully unscrew the prime plug.
- Fill the Pump: Using a funnel or hose, pour clean water into the opening until the pump housing is full and water starts overflowing.
- Replace Prime Plug: Once the pump is full, screw the prime plug back on tightly to prevent leaks.
- Turn on Power (Optional): For some pumps, you might need to turn on the power briefly to allow the pump to purge any remaining air. Consult your manual for specific instructions.
- Listen for Changes: As the pump starts working, you may hear a change in sound as the air is expelled and water fills the system.
- Repeat if Necessary: If water doesn’t flow after the initial attempt, repeat the process until the pump is primed and water runs freely from the designated outlet.
Additional Tips:
- Check for Leaks: While priming, inspect for any leaks around the prime plug or other connections. Tighten any loose fittings or replace damaged parts if necessary.
- Open Valves Gradually: Once the pump is primed, slowly open the valves on your sprinkler system to avoid a sudden surge of pressure.
By following these steps, you can prime your irrigation pump effectively and ensure a smooth startup for your sprinkler system.
