I got a call last summer from a woman out in Maple Ridge. She was almost yelling down the phone, not at me, just panicked. Her water bill had tripled. She’d already checked all the taps, the toilets, everything inside. Nothing. I said go look at your lawn while the sprinklers are running. She walked outside and straight up gasped. One corner was a swamp, actual mud, and the rest of the yard was barely getting a mist. The system had a leak. It had been dumping water for weeks, and she’d had no clue.
Happens more than you’d think. These inground irrigation setups, they’re buried in dirt, they get old, they shift, they get whacked by the lawnmower. But the signs are usually there if you know what you’re looking for. So let me just talk through the stuff we at Kinsley irrigation keep seeing over and over.
That water bill that makes no sense
If your bill’s creeping up month after month and you haven’t changed a thing, something’s up. Maybe it’s a busted sprinkler head, maybe a crack underground. Even a hole the size of a pencil lead can waste close to 700 gallons a day. That’s not a misprint. A single broken sprinkler head can dump over 10,000 gallons a month during summer. You’re basically watering the centre of the earth.
Quick way to check: turn off every tap in the house, make sure the sprinkler timer is off, then go look at your water meter. If that little dial is still spinning, water’s moving. Then turn on one irrigation zone. If it spins faster, that’s your leak. Simple as that.
A patch of lawn that always feels wet
After the system runs, everything should dry out at about the same pace. If you’ve got one spot that’s forever soggy, or it squishes when you walk on it like a wet sponge, the pipe underneath is probably cracked. Sometimes the grass there is weirdly green and grows twice as fast as everywhere else. That’s not because it’s happy. It’s getting extra water from a leak.
The flip side of this is just as common, dry brown spots even with regular watering. Same underlying problem, just showing up differently.
If you leave it, the soil under there can wash away and you end up with a sunken patch. I’ve seen lawns where the whole thing collapsed because water had been carving out a cave underneath. Bit of a shock when you’re mowing and suddenly the ground gives way.
Sprinklers not spraying right
You know how your heads normally look. If one that used to throw a beautiful arc is suddenly just dribbling, or the spray looks weak and patchy, the pressure’s off. Water’s escaping somewhere before it gets to the nozzle. Could be a crack in the line, could be a seal that’s gone.
Sometimes it’s just a bit of grit in the nozzle. Unscrew it, rinse it out, see if that sorts it. But if a bunch of heads in the same zone are all acting tired, you’ve almost certainly got a leak.
There’s a whole bunch of reasons why sprinklers end up spraying unevenly clogged heads, wonky pressure, valves not opening right and most of them are dead easy to check once you know what to look for.
Brown spots and wet spots in the same zone
This one throws people for a loop. You’ve got a patch that’s dust-dry and brown, and 20 feet away there’s mud. Same system, same timer. The brown bit is starving because the leak is stealing pressure. The wet bit is sitting right over the leak. So the whole zone looks like a patchy mess.
Don’t just crank up the watering time to fix the brown patch. You’ll drown the wet spot and still not reach the dry one. Gotta find that leak.
Water bubbling up or a puddle that won't go
This is the one you can see. Little bubbles coming up through the grass while the system’s running, or a tiny puddle that hangs around for days after it last rained. There’s a break down there and water’s pushing up through the dirt. Even a slow leak like this adds up. I’ve seen families use double their normal water without ever seeing a puddle, just from a slow underground leak.
If you spot bubbling, shut the system off and get someone out. These are the leaks that cause real damage if you ignore them. Erosion, sinkholes, the works.
What causes all this in the first place?
Mostly just time. Pipes get brittle. Frost heave moves the ground and snaps fittings. A tree root wraps around a line and squeezes. A kid’s trampoline leg comes down on a pop-up head. The mower guy clips one and cracks the casing just enough to leak without anyone noticing. It’s always something.
What to do if you see any of this
You could grab a shovel and start digging. I’ve seen plenty of blokes try. But unless you know where the line runs, you’re mostly just making a mess. You dig one hole, nothing. Dig another, still nothing. Your lawn looks like a war zone and you still haven’t found the leak.
A decent irrigation tech can trace the line, pressurize the system, and pinpoint exactly where the problem is without tearing up your whole yard. They’ll spot other stuff too: a valve that’s not closing tight, a head that’s about to fail and save you another headache down the road.
Stuff people ask a lot
Nope. If the valve for that zone isn’t closing all the way, water keeps seeping through 24/7. That’s how you get a soggy spot that never dries.
Way more than you think. I’ve seen small leaks rack up thousands of gallons in a billing cycle. It’s not just the water cost, it’s the damage to your lawn.
Absolutely. Run each zone one at a time, walk the yard, look for wet patches, listen for hissing, watch how the heads spray. And do that meter check I mentioned. Takes ten minutes and tells you straight up if there’s a problem.
At least once a year, in spring when you fire it up again. And do a quick walkaround every few weeks in summer.
That’s exactly what we do. Kinsley Irrigation can take your existing setup, add zones, swap spray heads for drip, install a smart irrigation system, and handle the backflow testing and permits. We sort the whole thing so you don’t have to mess with it.
The bottom line
Your irrigation system’s underground doing its job, and you probably never think about it. But a bit of attention now and then, a glance at your water bill, a quick look at the lawn can catch a leak before it drains your bank account. If something smells fishy, don’t just hope it’ll go away.
If you’re around Maple Ridge, the Fraser Valley, or anywhere in Greater Vancouver and you’ve got a weird wet spot, a bill that’s making you sweat, or sprinklers that just aren’t hitting like they used to, give us a shout at Kinsley Irrigation. We’ve been doing this stuff for over 20 years, installed systems in more than 500 homes. We’ll come have a look, tell you straight what’s going on, and sort it without wrecking your lawn. No big sales pitch, just a system that does what it’s supposed to
