Sprinklers acting up? You’re not alone. Many homeowners deal with sprinkler systems that suddenly stop working right — maybe a zone won’t turn on, water pressure’s too low, or one head shoots water into the street. The good news: a lot of sprinkler problems are fixable, even without calling a pro (at least at first). Here’s how to figure out what’s going on and what to do about it.

Common Sprinkler Problems and How to Fix Them

1. Broken or Clogged Sprinkler Heads

What to look for: Heads that are spraying water sideways, not popping up, or leaking at the base.

How to fix it:

  • Turn off the system.
  • Dig carefully around the head and unscrew it.
  • Check for dirt or debris; rinse it out or replace it if it’s cracked.
  • Screw in the new or cleaned head and test the zone.

2. Low Water Pressure

What to look for: Weak spray, uneven coverage, or some heads not popping up.

How to fix it:

  • Make sure the valve for that zone is fully open.
  • Check for leaks or clogs along the line.
  • Look at your backflow preventer — it may be partly closed.
  • If pressure is low across the whole system, it could be a city water issue or mainline problem.

3. Sprinkler Zones Not Turning On

What to look for: One area of your yard isn’t getting any water.

How to fix it:

  • Check the controller: is the zone programmed correctly?
  • Make sure the wire to the zone valve is connected.
  • Manually open the valve — if it works manually but not from the controller, it’s likely an electrical or controller issue.

4. Controller or Timer Malfunctions

What to look for: System doesn’t turn on at all or runs at the wrong times.

How to fix it:

  • Check if the controller has power.
  • Replace the backup battery if needed.
  • Reprogram your schedule — some systems reset after a power outage.
  • If it’s still not responding, the controller may need replacement.

5. Leaks or Water Pooling in the Yard

What to look for: Wet, soggy spots when the system is off.

How to fix it:

  • Turn off the water to the system.
  • Dig carefully to find the leak (often near fittings or pipe joints).
  • Replace cracked pipe or fittings using PVC or poly pipe connectors.
  • If you can’t locate the source, call a pro — underground leaks are tough to track down.

When to Call a Professional

Some sprinkler problems need expert tools or experience to fix:

  • Underground leaks that keep coming back
  • Wiring issues or full system rewiring
  • Broken valves that won’t open or close
  • Controller replacements or system upgrades
  • Full irrigation redesign or rerouting

Trying to tackle those without the right tools can cost more time and money in the long run.
