Slab Leaks:
Signs & Causes
Why Rerouting a Water Line May Be Better
Common Signs of a Slab Leak
Some common warning signs include:
-
An unexplained increase in your water bill
-
The sound of running water when everything is turned off
-
Warm or hot areas on the floor
-
Damp carpet or flooring
-
Water appearing around baseboards
-
Reduced water pressure
-
Unexplained moisture inside the home
-
A water meter that continues moving when no water is being used
One symptom doesn't automatically mean you have a slab leak, but unexplained water usage should be investigated.
What Is a Slab Leak?
A slab leak occurs when a water line located underneath a home's concrete foundation begins leaking.
The failure can occur on either a hot or cold water line. Because the pipe is buried beneath the foundation, homeowners often notice the symptoms before they ever see the actual leak.
Left unaddressed, a slab leak can waste a significant amount of water and potentially damage flooring and other building materials.
Slab Leaks
A slab leak can be one of the most frustrating plumbing problems a homeowner faces. Unlike a leaking faucet or running toilet, the problem is often hidden underneath several inches of concrete, making both detection and repair more complicated.
At AMP | Arlington Mansfield Plumbing, we believe finding the leak is only the first step. The bigger question is:
What is the best way to repair it without unnecessarily tearing apart your home—and without setting you up for another repair later?
After more than 28 years in the plumbing industry, I've seen slab leaks repaired just about every way possible. When the home's construction and plumbing layout allow it, an overhead water-line reroute can often be a better long-term alternative to jackhammering through the foundation or tunneling underneath the house.
What 28 Years of Slab-Leak Repairs Taught Me
This is one of the biggest reasons my approach to slab leaks has changed over the years.
I've been plumbing for more than 28 years, and in the earlier days of my career, jackhammering through floors to make individual slab-leak repairs was common.We would locate the leak, remove the flooring, break through the concrete, dig down and expose the damaged pipe.And something kept happening.We would frequently uncover a coupling or evidence of another previous repair only six inches to a foot away from the new leak.That tells you something about what's happening underneath that foundation.The previous leak had been repaired, but the remaining original pipe was still there. Eventually another weakened area became the next point of failure.Think about it this way:You repair the weakest point in the pipe. That repaired section is now strong. But you haven't necessarily changed the condition of the original pipe surrounding it.The next weakest point can become the next leak.
I've seen homeowners go through the expense and disruption of opening a slab, repairing a leak, restoring the floor—and then experience another underground leak nearby later.
That experience is one of the biggest reasons I believe homeowners should consider the condition of the entire affected line, not simply the hole that's leaking today.
Why Not Just Repair the Leaking Spot?
Sometimes a spot repair is absolutely the correct solution.
But a spot repair does exactly what its name suggests:
It repairs that spot.
It doesn't necessarily address deterioration, wear, previous repairs, or other weaknesses farther down the same underground water line.
That's why the age and condition of the plumbing system, previous leak history, pipe material, water pressure, and location of the failure should all be considered.
If we're looking at a water line that has already experienced multiple underground failures, repeatedly opening the foundation to repair individual weak spots may not be the best long-term strategy.
That's when an overhead reroute can become particularly attractive.
Top 10 Reasons to Consider an Overhead Water-Line Reroute
-
It eliminates the failed underground section. Rather than continuing to rely on the affected section beneath the foundation, it can be abandoned and bypassed completely.
-
You may avoid jackhammering your home's concrete slab. Direct access can require removing finished flooring before breaking through the concrete foundation.
-
You may avoid extensive tunneling. Depending on the location of the leak, accessing the plumbing from underneath can require significant excavation.
-
There's generally less disruption inside the home. A reroute can often travel through walls, ceilings, attic space, or other accessible areas using relatively small access openings.
-
It may reduce restoration work. Slab access can involve tile, hardwood, carpet, baseboards, cabinetry, concrete and other finished materials.
-
The new water line is more accessible. Plumbing located in accessible areas is generally easier to inspect and service than piping buried underneath several inches of concrete.
-
You're no longer depending on the same failed underground section. If deterioration or physical stress contributed to the first leak, repairing one opening doesn't necessarily change the condition of the remaining pipe.
-
It can avoid disturbing the foundation unnecessarily. When a safe alternate route exists, opening the concrete may simply not be necessary.
-
It can provide a better long-term solution. A spot repair addresses today's failure. A properly designed reroute bypasses the affected underground section.
-
It may make better financial sense. Homeowners should consider the entire cost—not simply the plumbing repair. Concrete demolition, excavation, flooring replacement, cleanup and restoration can significantly affect the final cost of a slab repair.
Another Concern With Jackhammering Concrete: Silica Dust
There's another issue homeowners may not immediately consider.
Concrete contains crystalline silica. Jackhammering, drilling, cutting or grinding concrete can create extremely fine particles known as respirable crystalline silica dust. These particles can be small enough to travel deep into the lungs when inhaled. Repeated or significant occupational exposure to respirable crystalline silica is associated with serious health problems, including silicosis, lung cancer, chronic obstructive pulmonary disease (COPD), and kidney disease. Silicosis is particularly serious because silica particles can cause inflammation and permanent scarring of lung tissue. This doesn't mean concrete can't be safely opened when necessary. Professional contractors can use engineering and work-practice controls such as wet methods, dust-extraction systems, HEPA filtration, containment and appropriate respiratory protection to reduce exposure. But if the concrete doesn't need to be broken in the first place, an overhead reroute may eliminate that part of the project entirely.
My Philosophy After 28 Years in Plumbing
Experience changes the way you look at these problems.
After years of opening foundations and seeing previous couplings and repairs sitting inches away from new failures, I stopped looking at every slab leak as simply a hole that needed to be patched.
I started asking a different question:
What gives this homeowner the best chance of not having to go through this again?
Sometimes that's a direct repair.
Sometimes it's tunneling.
And sometimes the better solution is to stop depending on that underground section altogether and reroute the water line overhead.
That's why we believe homeowners deserve to understand all of their options before someone starts jackhammering their floor.
