💧 Sprinkler Valve Repair: The #1 Reason a Zone Won’t Turn Off One of the most common irrigation problems homeowners run into is a sprinkler zone that won’t shut off. The system finishes its cycle, the controller says the zone is off… but water keeps running. In 90% of cases, the problem isn’t electrical. It’s inside the valve itself. Let’s break down how to diagnose and repair it. 🔍 What a Sprinkler Valve Actually Does Your sprinkler valve is basically a water-controlled gate. When the controller sends 24 volts to the solenoid, it opens the valve and lets water flow to that zone. When the power shuts off, the valve should close and seal tight. If it doesn’t seal, water keeps flowing. 🚨 Signs Your Valve Needs Repair Look for these symptoms: • One sprinkler zone won’t shut off • Heads leaking water constantly • A zone turns on randomly • Low pressure in a zone • Water pooling around the valve box Most of the time the culprit is inside the valve body. 🔧 The Most Common Valve Failure Inside every sprinkler valve is a rubber diaphragm. Over time it can fail because of: • Dirt or sand trapped under the seal • Small rocks or debris in the valve • A torn diaphragm • A cracked valve spring • Mineral buildup Even a tiny grain of sand can keep a valve from sealing. 🛠 Basic Valve Repair Process If you’re comfortable doing basic repairs, here’s the general process: 1️⃣ Shut off the irrigation main water supply 2️⃣ Open the valve bonnet (usually 4–8 screws on top) 3️⃣ Remove the diaphragm 4️⃣ Inspect for damage or debris 5️⃣ Clean the valve body thoroughly 6️⃣ Replace the diaphragm if worn or torn 7️⃣ Reassemble the valve Turn the water back on and test the zone. Many times this simple repair fixes the problem immediately. ⚠️ Pro Tip Most Homeowners Don’t Know Before you take the valve apart: Take a photo of the inside. Valve springs and diaphragms must go back in the exact orientation or the valve won’t work correctly. Even experienced techs do this. 💡 Another Common Mistake People often assume the solenoid is bad.

💧 Irrigation Troubleshooting Tip: How to Find a Hidden Sprinkler Leak (Without Digging Up Your Yard) One of the most common irrigation problems homeowners face is a hidden leak in the system. The tricky part is that the leak often isn’t obvious — you might not see water spraying anywhere. Here are 4 fast ways to diagnose it before you start digging. 1️⃣ Look for the Early Warning Signs Hidden irrigation leaks usually show themselves through subtle clues. Watch for: • One area of the yard that is always soggy • A sprinkler zone with lower pressure than the others • Water slowly flowing from a head after the zone shuts off • Your water bill suddenly increasing If you see two or more of these signs, there’s a strong chance a leak exists somewhere on that zone. 2️⃣ Run Each Zone Individually Turn your system on manually and run zones one at a time. Pay attention to: • Weak spray patterns • Bubbling water in the soil • Heads not popping up fully • A section of grass getting flooded Leaks often happen in fittings between heads, not at the head itself. 3️⃣ Listen for Water Underground This is an old trick many pros use. Turn the zone on and walk slowly along the pipe route. Sometimes you can actually hear: • A faint hissing sound • Water rushing underground • Soil vibrating slightly Those sounds usually mean a cracked fitting or pipe split nearby. 4️⃣ Check the Meter Test (Pro Trick) This is the fastest way to confirm a leak. Shut off all irrigation zones Make sure no water is running inside the house Look at your water meter If the meter is still moving, you’ve got water escaping somewhere. ⚠️ Where Most Irrigation Leaks Actually Occur From experience, the majority of leaks are caused by: • Broken swing joints • Cracked PVC fittings • Roots pushing against pipe • Lawn equipment hitting sprinkler heads • Cheap fittings that failed over time

💧 Leak Detection Lesson: The 3 Signs Your Irrigation System Is Losing Water Underground One of the most expensive irrigation problems isn’t a broken sprinkler head you can see — it’s the leak you can’t see. Underground leaks waste water, lower pressure, and can quietly destroy landscaping. Here are the three fastest ways professionals detect leaks in irrigation systems. 1. The Wet Spot That Never Dries If you notice a patch of turf that stays soggy or greener than the surrounding lawn, that’s a classic underground pipe leak. What’s happening: Water is escaping from a cracked lateral line or fitting and saturating the soil constantly. What to check: Soft soil when you walk over it Mushy turf Grass growing faster than the surrounding area 2. Low Pressure in One Zone If a zone suddenly looks weak — heads barely popping up or spray distance reduced — pressure is being lost somewhere in that line. Common causes: Cracked poly pipe Broken PVC fitting Split funny pipe at a sprinkler head A leak steals pressure before it reaches the rest of the heads. 3. The Meter Test (Pro Trick) This is one of the fastest ways to confirm a leak. Steps: Turn off all irrigation zones Go to the water meter Watch the leak indicator dial If it’s spinning while the system is off, water is going somewhere — and it shouldn’t be. Quick Pro Tip Most irrigation leaks happen in three places: Right beside sprinkler heads At pipe fittings or tees In areas where equipment or vehicles drive over the lawn Always check these spots first before digging up the whole yard. Why This Matters A small irrigation leak can waste thousands of gallons per month, and most homeowners never notice until the water bill spikes. The faster you detect it, the easier the repair. 💧 Question for the community: What’s the most difficult irrigation leak you’ve ever had to find?

💧 IRRIGATION LESSON: The 60-Second Sprinkler Valve Test Every Homeowner Should Know Most homeowners think a sprinkler valve is bad the moment a zone won’t turn on or shut off. In reality, 8 out of 10 valve problems are electrical — not mechanical. Here’s a quick test you can teach customers (or do yourself) in about 60 seconds. Step 1 — Turn the Zone On at the Controller Go to your irrigation controller and manually start the zone that isn’t working. Now walk to the valve box. Listen closely. You should hear a soft click or hum when the controller sends power to the solenoid. No sound at all? You may have a wiring problem or a bad solenoid. Step 2 — Use the “Quarter-Turn Test” Grab the solenoid on top of the valve. Turn it ¼ turn counter-clockwise. If water suddenly starts flowing to the sprinklers, the valve itself is fine. That means the real issue is usually: • bad solenoid • broken wire • controller output issue Step 3 — Turn It Back Turn the solenoid ¼ turn back clockwise to close it. If the sprinklers shut off immediately, you’ve just confirmed the valve body and diaphragm are working. What This Test Tells You Valve opens manually = Electrical problem Valve won't open manually = Mechanical problem inside valve Pro Tip from the Field Most pros carry extra solenoids on the truck because replacing one takes under 2 minutes and fixes a huge percentage of valve issues.

💧 The Hidden Irrigation Leak That Drains Your System (And Your Wallet) One of the most common irrigation problems we see is a leak that no one can find. The controller is working. The valves are opening. The heads pop up. But something still isn’t right. Maybe you notice: • A zone losing pressure • A soggy spot that never dries • A valve box filling with water • A water bill that suddenly jumps • A pump that runs longer than normal Most of the time, the leak isn't where people think it is. Homeowners usually assume the leak is at a sprinkler head… But in the field, the real culprits are often: 1️⃣ Swing joints cracking underground These are flexible fittings that connect the head to the lateral line. They crack over time and leak slowly underground. 2️⃣ Lateral line splits Tree roots, trenching, or ground shifting can split a PVC line and cause major pressure loss. 3️⃣ Valve diaphragm leaks A damaged diaphragm can allow water to slowly pass through the valve even when the zone is off. 4️⃣ Fittings that loosen over time Adapters, elbows, and tees inside valve boxes are common leak points. 5️⃣ Freeze or impact damage Even in Georgia, shallow pipe can crack during cold snaps or from heavy equipment. The key to leak detection is thinking like water. Water always takes the path of least resistance, which means the visible wet spot might actually be 10–30 feet away from the real leak. That’s why professional irrigation diagnostics follow three steps: 1️⃣ Pressure check 2️⃣ Zone isolation 3️⃣ Visual and acoustic inspection Once you isolate the zone, the leak usually reveals itself quickly. 👇 Community Question What’s the toughest irrigation leak you’ve ever had to track down?
