Misting and Fog: Is Your Sprinkler Pressure Too High?

Have you ever noticed your sprinklers creating a fine, fog-like mist instead of delivering solid streams of water? This is a classic sign of excessive water pressure. When the pressure is too high, the water atomizes into tiny droplets that are easily carried away by the wind and evaporate before they can even reach the soil. The result is wasted water and a thirsty lawn with stubborn dry spots.

How to Diagnose Misting

• Look for a “Fog” Effect: The spray coming from your sprinkler heads looks more like a cloud than a pattern of water droplets.
• Notice Drifting Mist: On a breezy day, you can see the mist blowing onto your driveway, sidewalk, or neighbor’s property.
• Identify Uneven Coverage: Your lawn has distinct dry patches, even though the sprinklers seem to be running everywhere.

Quick Fixes You Can Try

1. Check for Clogs: Before assuming it’s a pressure issue, check the filter screen at the base of the problem sprinkler head. Debris can cause a spray pattern that looks like misting. Unscrew the head, remove the filter, rinse it clean, and reinstall.
2. Adjust the Flow Control: Some valves in your valve box have a flow control handle. If your entire zone is misting, you can try turning the handle clockwise slightly to reduce the flow and pressure to that specific zone.

When to Call a Pro: If simple checks don’t work, the problem is likely systemic. Fixing high pressure often requires installing pressure regulators at the main line or valve, which is a job for a licensed irrigator. We can also swap your old heads with modern, pressure-regulated sprinkler heads that automatically maintain the perfect pressure for optimal coverage. This ensures every drop of water counts.

Water Pooling: Soggy Spots and Standing Water

Puddles in your yard long after the sprinklers have turned off are more than just an annoyance. They can signal a significant leak, suffocate your grass roots, attract pests like mosquitos, and encourage fungal growth. Water pooling indicates that a specific area is receiving far more water than it can absorb.

How to Diagnose Water Pooling

• Persistent Soggy Spots: The ground is marshy or squishy in one or more areas, even on hot, dry days.
• Fungal Growth: You see mushrooms or green algae forming on the soil surface in the wet area.
• Visible Erosion: Soil is washing away around the soggy zone, especially on slight slopes.

Quick Fixes You Can Try

1. Inspect the Sprinkler Head: The most common cause is a broken or tilted sprinkler head near the puddle. Look for cracked plastic casings or heads that have sunken below the soil level, causing water to gush out at the base.
2. Check Run Times: If the pooling is widespread, you might be overwatering. Try using a “cycle and soak” schedule on your controller. Instead of one long 30-minute run, schedule three 10-minute runs with an hour in between. This gives our dense clay soil time to absorb the water.
3. Clean a Leaky Valve: If a zone continues to seep water when it’s off, you may have a valve stuck open with debris. After shutting off the water to your system, you can open the valve box, unscrew the solenoid and top of the valve, and clean out any dirt or small pebbles you find inside.

When to Call a Pro: If you suspect a stuck valve and aren’t comfortable opening it, or if you can’t find the source of the leak, it’s time to call for backup. We can locate and repair underground leaks, replace faulty valve diaphragms, install check valves to prevent low-head drainage, and professionally raise sunken sprinkler heads to ensure they function correctly.

Manual Override Not Working? Controller Chaos

Your sprinkler controller is the brain of the operation, but sometimes it refuses to listen. You might try to run a zone manually to test a repair, but nothing happens. Or worse, a zone won’t shut off, and your yard is turning into a lake. These issues can stem from the controller, the wiring, or the valves themselves.

How to Diagnose Manual Issues

• Zones Won’t Start Manually: You try to turn on a specific zone from the controller, but the sprinklers don’t pop up.
• Zones Won’t Stop: After running a cycle, one zone keeps watering indefinitely.
• Entire System is Dead: The controller display is blank, or no zones will activate at all.

Quick Fixes You Can Try

1. Check Controller Settings: Make sure the controller isn’t in the “Off” or “Rain” mode. If you have a rain sensor, check that it’s dry and not signaling the system to stay off. Most controllers have a bypass switch for the sensor.
2. Look for a Master Valve: Many systems in Rowlett have a master valve that opens whenever any zone is activated. If your controller clicks but no water comes out on any zone, you may have a problem with the master valve or its wiring.
3. Test the Solenoid: At the valve box, find the solenoid for the problematic zone (it’s the cylinder with wires coming out of it). Gently twist it counter-clockwise about a quarter turn. This should manually open the valve. If water flows, the valve is likely good, and the problem is electrical (the solenoid or wiring). If it still doesn’t run, the valve itself might be the issue.

When to Call a Pro: Electrical issues are tricky and best left to experts. A professional technician can use a multimeter to trace wiring faults, diagnose a bad controller, and replace faulty solenoids or valves quickly and safely. If your controller is old, we can also recommend and install a modern smart controller that you can operate from your phone.

Unsightly Water Stains on Pavement

Hardscapes like driveways, sidewalks, and patios are expensive. The last thing you want are ugly, hard-to-remove stains from sprinkler overspray. These stains are caused by minerals and sediments in the water constantly soaking the concrete or stone. Besides being an eyesore, it’s a clear sign of water waste.

How to Diagnose Overspray

• Wet Pavement: This is the most obvious sign. Run the zone and watch where the water lands. Is it hitting the pavement?
• Visible Stains: You see white, brown, or rust-colored streaks on your hardscapes that line up with your sprinkler heads.
• Windy Day Woes: The spray pattern looks fine on a calm day, but any amount of wind pushes the water onto walkways.

Quick Fixes You Can Try

1. Adjust the Arc and Radius: Most modern sprinkler heads can be adjusted. Use a small screwdriver or the manufacturer’s key to reduce the spray radius (distance) or adjust the arc (the pattern, from 45 to 360 degrees) so it only waters the lawn.
2. Swap the Nozzle: If adjusting doesn’t solve it, you may have the wrong nozzle installed. Nozzles come in various trajectories and distances. You can unscrew the existing nozzle and take it to a hardware store to find one with a shorter throw or a different spray angle.

When to Call a Pro: Sometimes, the head is simply in the wrong place. To stop overspray permanently, we might need to move the sprinkler head, switch it to a more precise nozzle, or even install drip irrigation along the edge of the hardscape. These are solutions that provide a long-term fix and maximize your water efficiency.

Frequently Asked Questions

1. Question: What is the ideal water pressure for a sprinkler system?
   Answer: For most residential spray heads, the ideal pressure is around 30 PSI. Rotor heads, used for larger areas, perform best between 40-50 PSI. Anything significantly higher will cause misting and inefficiency.
   
   
2. Question: How often should I inspect my sprinkler system?
   Answer: We recommend running each zone manually for a few minutes at least once a month during the watering season. Walk your property and look for leaks, broken heads, clogged nozzles, and overspray. A quick monthly check can save you hundreds of gallons of water.
   
   
3. Question: What are the signs of a hidden underground leak?
   Answer: Besides an unexpectedly high water bill, look for soggy spots, areas of unusually green grass, or a loss of pressure across an entire zone. You might also hear a faint hissing sound underground after the system has shut off if the leak is near the surface.
