over 1,500 reviews

Discovering an underground water leak on your property is one of those headaches no homeowner wants to deal with. Unfortunately, these pesky plumbing problems often go undetected for months or even years, wasting gallons upon gallons of treated water in the process. Worse yet, the erosion caused by persistent leaks can compromise your home’s structural integrity if left unchecked.

The good news? There are telltale signs that can alert you to an underground leak’s presence before it becomes a catastrophe. Things like suspiciously lush patches of grass, water pooling in your yard, or sudden spikes in your monthly utility bills all point toward a buried pipe springing a leak somewhere.

In this guide, we’ll dive into the most common red flags that signal an underground water leak may be slowly draining your wallet. We’ll also cover what causes these leaks in the first place, how to pinpoint their location, and what professional solutions exist for proper leak repair. Stay vigilant for any of these clues – the sooner you catch a plumbing leak, the easier (and cheaper) it is to fix!

Leak Detection

Signs of an Underground Water Leak

From soggy spots in your yard to unexplained spikes in your water bill, underground leaks can manifest in numerous subtle ways. Stay vigilant for any of these telltale signs:

Increased Water Bill

One of the biggest tip offs to an underground leak is an unexplained spike in your monthly water bill. While rate hikes and household usage changes could account for minor fluctuations, a significant and sustained increase likely points to a constant supply line leak steadily draining away treated water. Don’t just chalk up that higher bill to “running the sprinklers more” – it could be masking a much bigger plumbing problem.

Wet Spots in the Yard

As water persistently leaks from an underground pipe, it has to go somewhere – and soggy patches of grass are often where it ends up surfacing. If you notice any random areas of your lawn that always seem overly lush, damp or squishy underfoot with no logical explanation, put on your detective hat. Those are classic signs of a very wet leak slowly bubbling up to say hello.

Foundation Cracks

While cracks in a home’s foundation get written off for settling over time, excessive cracking patterns could also indicate something more sinister – steady erosion from an underground leak source. These hairline fractures reveal the powerful, gradual deterioration that can occur from a water leak’s persistent moisture and shifting soil pressures.

Sounds of Running Water

Got a weird whooshing or trickling sound constantly coming from your bathroom or water fixtures, even when they’re off? That noise could be the telltale sign of water steadily draining away through a cracked underground supply line. The eerie sound is your plumbing crying out for professional leak repair help.

Low Water Pressure

Notice that your shower barely puts out a trickle these days? Or doing minor tasks like running the dishwasher creates a drop in pressure on other fixtures? These are common plumbing side effects when your home’s water supply gets compromised by an underground leak source steadily bleeding out volume before reaching taps and appliances.

Pooling Water

Random puddles of water that show up on your lawn, driveway or basement with no rhyme or reason are practically leaving a neon “Leak Here!” sign for you to follow. Whether they manifest overnight or emerge after heavy rainfall, unexplained pooling points to underground water supply line compromises that need immediate attention.

Unusual Plant Growth

While spotting extra lush areas in your yard could signal an unseen leak nearby, pay extra close attention to any confused plants and shrubbery sprouting up in places they shouldn’t be. Nutrient-filled leaking water encourages accelerated vegetation growth, even in barren areas. Let your greenery be your guide toward pesky plumbing problems.

Muddy or Soft Ground Areas

As excess water slowly leaks from any underground pipes over time, it can turn solid soil into swampy marshlands around your property. Backyards with random patches of muddy, overly soft or loose terrain that seem out of place could have hidden leaks creating consistent moisture buildup below the surface.

Discolored Water from Taps

While seeing brown, reddish or cloudy water coming from faucets triggers fears of contamination, it could also indicate an aging, corroded pipe leaking sediment into your home’s main supply line from underground. Once the discolored water persists across multiple fixtures, start hunting for that underground source right away.

Warm Spots on the Floor

Feeling any suspiciously hot patches radiating up through certain floor areas, even in winter? Those could be the result of heated water steadily leaking from underground piping and transferring its temperature up through your home’s subfloor or slab. Don’t just write off that radiant bathroom flooring as a luxury!

Heaving or Buckling Pavements

As persistent underground leaks slowly erode and wash away supportive soils, they place excess pressures on any surface hardscaping like driveways, sidewalks, and patios above. This causes unsightly cracks, heaving, and buckling you’d normally associate with a sinking foundation. But those pavement shifts could originate from an undetected leak source.

Mildew or Moisture Under Carpets

That funky, mildew smell constantly wafting through certain rooms could signal more than just an overdue carpet cleaning. When moisture from an underground water leak eventually rots wood flooring underneath and gets absorbed up through carpet fibers, you’ll definitely start to notice weird odors and dampness. Investigate further before assuming the worst!

While some of these red flags could stem from other sources, multiple occurrences point toward an underground water leak slowly sapping your home’s pipe integrity. If you notice a combination of these signs, it’s time to call in the leak detection experts.

How Can I Confirm if I Have an Underground Water Leak?

So you’ve noticed some of those telltale signs of a potential underground leak lurking on your property. Before calling a plumber and starting expensive repair work, you’ll want to get confirmation that your suspicions are correct.

Some proactive detective work never hurts! Try giving these simple at-home tests a shot to better pinpoint whether your home’s water supply lines have truly sprung an underground leak:

Meter Key Test

One of the easiest ways to check for a leak when all fixtures are off? Head out to your water meter box, remove the cover, and closely watch the meter’s leak indicator (usually a small triangle or gear). If you notice any movement at all when no water is being used inside, bingo – you’ve got a leak somewhere drawing from the supply line.

Pressure Test

For this method, make sure no water is running inside or outside your home, then carefully check your meter reading. Wait an hour or two without using any water, then recheck that meter reading. If the numbers have changed at all, it confirms you have a leak pulling water through the system when nothing should be running.

Shut-Off Test

Another technique is turning off your home’s main water shut-off valve, then checking your meter reading. Wait several hours and check that meter reading again – any change with the supply valve completely closed off means you’ve got a pressurized leak before that shut-off point drawing water through.

While passing these basic tests indicates a likely leak situation somewhere in your plumbing system, they don’t necessarily pinpoint whether that leak extends into buried underground piping or exists in exposed areas. For precise leak source detection and water line repairs, your best bet is calling trained residential plumbing professionals with specialized tools and methods.

Reimer’s team leverages cutting-edge leak detection equipment to quickly and accurately locate any compromised pipe areas without excessive digging or property damage. Whether originating from hazardous slab leaks or sneaky supply line cracks far underground, we’ll get to the bottom of your plumbing woes. The first step is confirming suspicions through simple at-home tests – then it’s time to call in reinforcements!

What Causes Underground Water Leaks?

Once those at-home tests confirm you’re dealing with a persistent leak situation, the next question is – what’s allowing all that treated water to escape from your buried supply lines in the first place? Unfortunately, underground leaks can stem from a variety of culprits slowly compromising your home’s plumbing integrity over time.

Pipe Corrosion

Of all the leak catalysts, corrosion reigns supreme as Enemy #1 for any buried pipe materials like copper, steel, or even plastic lines. Whether from normal electrochemical deterioration, excessive soil acidity, or long-term exposure to our region’s heat and moisture levels, that constant underground corrosion inevitably leads to pinhole leaks or full blowouts.

Loose Joints or Fittings

Those critical transition points and connections connecting pipes together often create weak spots prone to leaks as they shift, settle, and come loose over decades underground. Improper original installation practices can expedite these tiny separations that allow water to start steadily escaping.

Shifting Ground Pressures

Our region’s weather creates a perpetual swell/constrict cycle that places intense physical pressure on buried pipe infrastructure. As that surrounding soil compacts and expands, it can crack even the toughest plumbing materials.

Tree Root Infiltration

You know how insistently pervasive tree roots can be in their endless search for moisture sources. Those persistent roots will have no problem puncturing and wrapping around any plastic or metal plumbing lines in their path, creating obstructed leaks over time.

Mechanical Damage

Whether from recent home renovations and landscaping projects, or aging public utility work occurring near your property lines, any accidental strikes to buried pipes often leave behind hairline cracks and vulnerable leak spots just waiting to spring forth.

Improper Pipe Bedding

Sometimes leaks happen not because of material failures, but because drainage piping was installed incorrectly using poorly compacted bedding materials that later shift and stress pipe walls. Doing things right at the ground level avoids so many buried headaches down the road.

Old Age and Deterioration

At a certain point, even the most high-quality piping systems inevitably reach the end of their expected lifespans underground. As those plumbing materials gradually deteriorate due to age, leaks become impossible to avoid without full replacement.

From corrosion and loose joints to excess ground forces and encroaching tree roots, a variety of formidable enemies can turn your buried pipes into a ticking leak time bomb. Preventing these situations through proper materials and installation provides the best long-term defense.

How Can an Underground Water Leak Be Located?

Finding the precise source location of an underground leak is often easier said than done. Those pesky compromised pipes could be buried practically anywhere across your property line – under landscaping, driveways, patios, or your home’s very foundation itself.

Hiring trained leak detection professionals makes all the difference in quickly pinpointing that problem area without excessive digging and property damage. At Reimer, we leverage a wide array of specialized tools and strategies perfected over decades:

Electronic Leak Detection

Using extremely sensitive ground microphones and amplifiers, our technicians can sometimes quite literally listen in for telltale leak sounds by scanning across your property piece-by-piece. Those high-pitched water turbulence noises lead us straight to compromised piping no matter how deeply buried.

Tracer Gas Monitoring

In cases where audible techniques fall short, Reimer can directly inject inert-friendly gases into your plumbing system while monitoring potential leak areas with detection wands or ground probes. Any gas escaping indicates a compromised pipe section.

In-Line Camera Inspection

Sometimes visual confirmation proves more valuable than any instrumental data. Our plumbers utilize advanced yet portable camera systems to inspect piping interiors by snaking the line. We’ll see every crack, root intrusion, or questionable section up close.

Ground Penetrating Radar

For even more challenging cases, ground penetrating radar (GPR) provides detailed subsurface imaging from above-ground to map out underground utilities, piping routes, soil conditions, and more. This illuminates unseen leak sources without risky exploratory digging.

Thermal Imaging Surveys

Where heated municipal water sources are involved, cutting-edge infrared cameras can literally see temperature anomalies radiating from buried leaks as that hot water escapes into surrounding soils. Warm zones become easy visual targets to isolate.

Once Reimer’s team combines multiple techniques to triangulate that leak’s precise location, we formulate a compact, efficient repair plan to swiftly resolve the issue with as little property disruption as possible. The right equipment and training makes all the difference!

What Should I Do if I Suspect an Underground Water Leak?

If you’ve noticed several telltale signs of a potential underground leak issue and those at-home detection tests seem to confirm your suspicions, it’s time to act fast. The longer you let those leaks persist, the more expensive repair bills and property damage they’ll inevitably cause.

First things first – shut off your home’s main water supply valve to prevent any further water loss and erosion risks until professionals can properly diagnose the situation. While this temporarily inconveniences your household, it also gives you breathing room before that leak escalates into an emergency.

Next, get on the phone and schedule a service call with trusted plumbing experts like the team at Reimer. We’ll have licensed technicians promptly deployed to your home armed with the latest underground leak detection equipment and methods.

Don’t panic if your initial attempt at explaining potential leak symptoms gets you an inevitable “We’ll have to take a look first” response. Experienced pros know better than to speculate on repair complexities sight unseen. Their first step will always involve careful on-site analysis to accurately identify that leak’s source point and extent.

However, being able to provide context clues during that initial call can better prepare technicians for issues they may encounter, such as:

  • Approximate area where you’ve noticed soggy ground or lush vegetation
  • Potential obstacles like landscaping, paving or buildings near suspected leak sites
  • Any known history of previous plumbing repairs or aging pipe materials
  • And most crucially – the specific leak detection tests you already tried

With this extra insight, Reimer’s certified plumbers will arrive ready to thoroughly investigate every potential leak source from the get-go rather than wasting time and money on guesswork. The more details you can provide upfront, the quicker we can confirm that underground leak’s location and formulate a repair plan to have you back up and running!

Can an Underground Water Leak Lead to More Serious Issues?

While a persistent underground leak might seem like a pesky plumbing problem at first, ignoring that steadily escaping water opens up a Pandora’s box of potentially catastrophic consequences. Prolonged moisture infiltration can wreak havoc on your home’s structural integrity and create major safety hazards if left unchecked.

Foundation Damage

As saturated soil surrounding those leaks steadily erodes away, it compromises the very earth meant to support your home’s entire weight. Those persistent moisture pockets displace load-bearing soil and allow sections of your foundation to settle unevenly. Hello, cracked walls and sticking doors/windows!

When leaks occur directly underneath the foundation itself, that excess hydrostatic pressure starts buckling and heaving the concrete from below. Those cracks then spiral into more rapid water infiltration, repeating the damaging cycle.

Dangerous Mold Growth

Any type of unchecked indoor moisture inevitably leads to mold and mildew infestations taking root behind walls, under floors, or within your duct system. Those fungi proliferate rapidly while pumping allergens and even toxic spores throughout your living space.

Prolonged mold exposure creates acute respiratory distress for inhabitants while steadily compromising your home’s structural wood and drywall components through rot and deterioration. It’s an unhealthy, expensive nightmare waiting to happen.

Sinkhole Formation

When major underground leaks are left to fester for years on end, they can quite literally start eroding away the subterranean soil strata and bedrock meant to anchor man-made structures to the earth itself. Those growing cavities and voids destabilize the ground, heightening risks of sudden sinkhole collapses swallowing vehicles, yards and even homes whole.

While sinkholes get associated more with naturally acidic aquifers and watersheds, any source of persistent high-volume water intrusion creates similar liabilities over time. Don’t let that seemingly minor plumbing drip turn into a looming sinkhole hazard!

From weakening your home’s literal foundation to enabling hazardous mold growth and even subterranean erosion, what seems like a small underground leak today can easily blossom into a much larger (and costlier) headache tomorrow.

Addressing those leaks head-on through proper detection and repairs helps circumvent structural damage, health concerns, and widespread property destruction further down the road. An ounce of prevention is worth a pound of cure when it comes to your household water supply!

How Are Underground Water Leaks Repaired?

Once certified plumbers leverage their array of high-tech detection methods to precisely locate that stubborn underground leak, it’s time to formulate a surgical repair plan. Depending on the issue’s severity and your plumbing system’s materials/layout, several different approaches could be prescribed:

Pipe Relining

In situations where leaks originate from pipes still in relatively good shape, our technicians can opt for cured-in-place piping (CIPP) relining. This trenchless repair method relays a resin-saturated liner inside the existing pipe to form an impervious new flow conduit. It bridges leaks and reinforces aging lines without major excavation.

Spot Repairs

For concentrated leak sources along accessible sections of supply lines, sometimes crews can simply isolate and replace just that small compromised pipe area through strategic digging. These surgical “spot repair” openings minimize landscape disruption compared to full-line replacements.

Line Replacements

Unfortunately, widespread leaks or severely compromised piping materials sometimes necessitate complete water line replacements. While more invasive, this provides an opportunity to upgrade to modern materials designed for superior leak resistance down the road.

Reimer always aims for trenchless approaches first to mitigate restoration costs and shade tree casualties. But rest assured, any excavation work follows carefully plotted utility marking and proper bedding/compaction protocols to maximize stability. We then repair ground areas to match their original appearances.

Leak Resolution Systems

For situations where precise leak locations remain elusive or only minor dampness exists so far, technicians can attempt injecting active sealants to stem leaks from within pipes themselves. These specialty products work almost like liquid adhesives to lock out moisture where it originates.

Slab Leak Restoration

Those dreaded slab leaks originating under concrete foundations rank among the most complex repair scenarios. Reimer has multiple potential remedies from rerouting visible plumbing to advanced slab jacking techniques that seal leaks while raising settled areas back to level positions.

No matter which approach proves most suitable for your particular underground leak case, you can count on Reimer to leverage well-considered solutions and finish every project with meticulous care. We’ll walk you through each remediation step and address any follow-up moisture concerns to prevent future leak issues.

The Bottom Line on Underground Leaks

While those initial signs of an underground water leak on your property may seem minor, taking a “wait and see” approach often proves unwise. Those steady trickles of escaping water carry serious risks of eventual structural damage, hazardous mold growth, eroding soil stability, and skyrocketing utility costs if left unchecked.

That’s why it pays to have seasoned leak detection professionals like the specialists at Reimer Home Services examine your situation at the first red flag. With decades of expertise pinpointing hard-to-find plumbing leaks across the greater New York region, our technicians leverage the latest tools and methods to quickly diagnose the problem with surgical accuracy.

From non-invasive electronic listening devices and camera inspections to ground-penetrating radar when needed, Reimer’s crew misses nothing when it comes to leak sources – even those buried deep underground. We’ll rapidly isolate the issue before it intensifies, then prescribe and execute the proper repair plan to permanently resolve leaks with maximum cost-effectiveness.
