Warning Signs You May Have a Hidden Leak

Most leaks are not visible. By the time you see water, significant damage may have already occurred. Call Lifeline right away if you notice any of the following:

1. Unexpectedly high water bills — A sudden spike in your water bill with no change in usage is one of the most common signs of a hidden leak.

2. Damp or discolored walls, floors, or ceilings — Staining, bubbling paint, or soft spots in drywall often point to water behind the surface.

3. Musty odors — A persistent musty smell in one area of your home is often caused by moisture buildup from a slow leak.

4. Sound of running water when no fixtures are on — If you hear water moving when nothing is in use, a pipe is likely leaking somewhere in your system.

5. Low water pressure — A sudden drop in pressure throughout your home can indicate a leak in the main water line.

6. Warm or wet spots on the floor — Hot water line leaks beneath a slab often create warm patches on concrete or tile floors.

7. Cracks in your foundation — Over time, slab leaks can erode soil beneath your foundation, causing cracks or shifts in the structure.

If you suspect a slab leak specifically, our team also specializes in slab leak detection and repair.

How Does Leak Detection Work?

There are a few different methods used to detect a leak. If it seems as though a leak has sprung somewhere in your system, the next step is finding its location. Using a variety of detection equipment, such as thermal leak detectors, is sometimes necessary for hard–to–find leaks. There are various approaches a plumber can take to discover a leak, whether it’s in the main water line or behind a wall. The first step, however, is knowing that you have a leak at all, and that’s largely the responsibility of the homeowner.

There are numerous reasons to consider leak detection service in Elgin and the Chicagoland area. When it comes to the integrity of your plumbing system, you need to make certain that it works well at all times. What you can expect after a leak has been properly identified and fixed?

  • Restored water pressure. Restoring your water pressure is one the most noticable outcomes. A serious leak in your home can not only place your belongings, walls, and floors at risk of damage, but it can also negatively impact your water pressure, which can make things like taking a hot shower in the morning difficult.
  • Reduced utility bills. A major water leak in your home can lead to high utility costs, depending on where the leak is located.
  • Water conservation. Another important consideration is water conservation. Whether you’re eco–conscience or not, conserving water is important to making sure that your local environment and community have the water they need to thrive.

When it comes to the integrity of your plumbing system, you should take all necessary precautions. With our professional leak detection services, your home will be in good hands at all times. Call us today to schedule a water leak detection service!

The technician showed up on time, offered several solutions to my issue and completely the work in a timely and professional basis. He coordinated with the city for their involvement and made the entire process very easy for me. The pricing was fair and reasonable and I can not think of a single thing they could…

Had lifeline out a few times after buying my new home for plumbing and HVAC. Kevin, Dustin, and Travis were all great. Melissa helped set everything up over the phone and she made things a breeze. I recommend anyone to Lifeline. 👍
