4 Signs of Sewer Backup

Before you experience a full sewer backup, there are a few indicators that it may be time for a through sewer cleaning or a trenchless sewer line replacement. If you know what to look for, you can save yourself time, stress, and money. Below are a few warning signs to keep an eye out for.

When More Than One Drain Is Clogged

It is not unusual for your drains to get clogged from time to time, but if more than one drain is clogged at the same time—it may be the sign of a bigger problem. This is of particular importance if one of the drains that is clogged is in a drain you rarely use, such as a guest bathroom, workroom sink, or laundry room sink.

Your Water Is Backing Up Into Other Drains

This is something that will be easiest to identify in your bathroom, because it has multiple drains. Water will typically backup in to a lower drain. For example, if your bathroom sink or toilet is backing up into the shower or bathtub—it is a sign that you need either a through sewer cleaning or a trenchless sewer line replacement.

However, keep an eye out for backed up drains in other areas of your home. A common example would if the toilet begins to unexpectedly overflow while you are using your washing machine.


Another great way to identify a sewer backup is the presence of bubbles. Bubbles are caused by trapped air caused from water trying to pass through the clogged area of the drain. To check for bubble, fill your sinks and tubs with a few inches of water—then watch for bubbles while they drain. Also watch your toilet to see if it bubbles after you flush.

Your Toilet Is Not Flushing Properly

One of the most common signs that you have a sewer backup, is that your toilets are not flushing properly. You can of course attempt to plunge your toilet, but if that does not immediately solve the problem—something bigger is likely going on.

As mentioned above, bubbles are a sign of a sewer backup—but keep in mind that it is normal for bubbles to occur directly after plunging.

Sometimes a sewer backup means you will need a trenchless sewer line replacement, but sometimes all you require is a through sewer cleaning. However, the longer you ignore a clog or blockage—the higher the potential for costly damage.
