WATER BUBBLING UP IN FAUCETS OR TUBS
Typically, the best indicator of a broken sewer line is when you turn on one fixture, like a sink faucet, and water bubbles up somewhere else, like the bathtub, indicating that things aren’t flowing the way they should be.
A SLOW DRAINING BATHTUB
A slow drain is an early sign that you might have a backed up sewer line. After trying to unclog it with a household plunger or auger, if you’re still experiencing slow draining in a sink, bathtub, or toilet, it’s likely you’re looking at a blockage.
SEWAGE BACKUP IN TOILET OR BATHTUB
This usually occurs in the lowest open drain and is due to some type of blockage. If by running water down a drain you cause some sort of backup, it’s likely your main line. But, if it’s only happening in one location, like at the kitchen sink for instance, then it’s probably isolated to that specific drain line.
SEWER ODOR AROUND YOUR PROPERTY
If you can smell sewage in or around your home, it’s a good indication that there’s a broken line somewhere. Other than the vent stacks on top of your house, your sewer system should have no open areas to let out gas or odors.
A broken sewer pipe behind a wall, combined with the right temperatures, can cause enough humidity to grow mold. Sacramento definitely has the right climate for this, so if you’re experiencing new mold growth, along with a sewage smell in your home, you probably have a busted sewer line.
A SUNKEN OR EXTRA GREEN LAWN
If you have a leak in your main sewer line, your lawn soil may become saturated with water or sewage. This can cause a dip in your lawn or can also act as fertilizer, so look out for extra lush green patches of grass.
FOUNDATION CRACKS OR SINKHOLES
In severe cases, the sewer line running under your foundation may be cracked. If it goes undetected for a length of time, a void can develop in the foundation, causing cracks, settling, or even sinkholes.
A RODENT PROBLEM
Oddly enough, the presence of rodents may be a strong indicator of a broken sewer line. Since they often live in the sewer system, they could make their way from the city main to your home’s piping. And if that piping is busted, they might just set up camp in your home.
