Of the many potential plumbing issues homeowners can face, sewer pipe trouble is considered one of the most costly. Often, homeowners won’t have a clue they have an undetected plumbing problem until they get their water bill. 

A massive spike in the water bill can be a clear indication of a sewer leak. If you suspect you have a sewer problem, it is recommended that you work with professionals and have a sewer camera inspection carried out as soon as possible.

Other telltale signs of sewer leaks you should look out for include:

Colored Water

Water from your faucet should be clear. If you have a sewer leak, water can turn yellow, brown, or green. However, colored water is not always an indication of an undetected sewage issue. Colored water can also be caused by rust in your plumbing system or a leaking pipe. Green water can also point to a corroding copper pipe. 

Sagging or Wet Floor

Another sign that can indicate a hidden water leak is a damp spot on your carpet. Water can seep upward when there are sewer leaks in the slab foundation of your home. Hidden leaks and concrete slab foundations often go hand-in-hand. 

Typically, pipes run through the concrete where they are kept hidden. If the leak is undetected for an extended period, you can end up with a damaged foundation.

Unexplained Odors

One of the very first signs that point to a sewer leak is unexplained odor. Most homeowners with a sewer leak would notice the smell of sulfur or eggs. The unpleasant smell is often attributed to gas that's released from an undetected plumbing leak. 

On the other hand, an eggy smell will not always indicate a plumbing problem or leak. At times, it can be traced to gas leaks from homes that use natural gas as a heating fuel. Either way, it is recommended that you have your pipes checked right away if you notice any unusual smell.

Slow Drain

If you notice your shower drains slowing down, the possible problem might be a hairball. Soap, hair, and other particles can also clog your drain and create sewer leaks. If the slow drain is in your kitchen, the problem can be caused by grease clogging the drain.

When every drain at home starts to move slowly, it can be an indication of a more severe issue like a sewer leak. If unsure, it would be best to seek help from professionals so the problem can be identified and fixed right away.

Old-Looking Pipes

Undoubtedly, visual inspection is one of the quickest and easiest ways to spot a possible sewer problem. Ideally, you should check for possible problems at least twice a year—before turning on the air conditioning and as soon as the temperatures drop.

Coupled with a frozen pipe, a sewer leak can turn into a plumbing disaster. Check the hidden area under your drain and look for possible joint leaks in your sewer system. Discoloration can also point to a possible leak. 

Water Pressure Drops Off

Contrary to popular belief, if you notice a low water pressure when running the dishwasher, taking a shower, or doing the laundry, it's not always a sign of an undetected plumbing problem. It is possible that your municipal water supply might be the culprit. 

If your water takes some time to drain and water pressure at every tap is low, there's a huge possibility you have a sewer leak. In some cases, a hidden mainline puncture might not leak into your home. Instead, it can flood your neighbor's property and keeps the problem hidden much longer.

Excess Water Pooling Outside

After a rain shower, a puddle or two can form. If you notice a puddle when it has not rained, it can indicate a problem with the drain system or an undetected sewer leak. Also, if you notice a sudden elevation change, it can be a sign of another issue like a collapsed sewer pipe. 

Also, if you notice the pipes backing up or a small pool forming, even if it's not raining, you're likely dealing with a hidden leak. It is recommended that you have your pipes checked to find the source of the leak and have it fixed.

Discoloration on the Walls

While unfortunate to note, most sewer leaks can stay undetected for months causing water to slowly seep throughout your home. A slow drip can also stay hidden for long periods if concealed behind your ceiling or wall.

Colored spots and dark rings that appear on the walls are not only unsightly, they can also indicate a leak that's hidden under the surface. Another clear sign of a sewer leak is bubbling or peeling paint or wallpaper. 

Final Thoughts

Sewer leaks can be very costly if left undetected for a long time. That said, if you notice any of the telltale signs above, get in touch with a professional so any issues can be resolved right away before they cause more damage.
