Perhaps the most obvious sign of a drainage problem is if the water in sinks, tubs, and other water fixtures isn't draining at all. However, before this happens, there will be a period of time when the drain begins to drain more and more slowly.

This is usually caused by buildup in the pipe. The buildup usually starts to accumulate on the pipe walls and builds outward toward the center. If someone notices the water has begun to drain slower than usual, it is best to call a plumber before the drain becomes completely clogged.

If a homeowner notices bad-smelling or discolored water coming up from their drain, this is called backflow. It is caused by some type of failure further down in the plumbing system. Sometimes, a sudden change in water pressure can result in the flow of the water through a system going in reverse.

This will cause sewer water to flow back up into the drains in the home.

Another issue that may be the result of sewer and drain problems is if there are bad odors coming from the sink or tub. In some cases, if the valve isn't closing as it should, it will allow the sewer gas to float up into the drain — just like the backflow issue.

If a homeowner starts to notice bad odors coming out of the drain, they should contact a plumber to help address the issue.

Seeing rodents or bugs in or around a home is never good. However, if there are pests that regularly visit a home, they may be coming from a crack in the sewer line.

In fact, rats and cockroaches are able to squeeze through virtually any size hole or crack. A persistent pest problem can be a surprising indicator of a deeper drain or sewer issue.

Does it seem like a home's utility bills are higher than usual? If so, the issue may be a hidden leak. Regardless of the size, investing in a camera inspection done by a professional plumber ensures the source of the problem is found.

After this, investing in plumbing maintenance is a smart move to prevent further issues.

Issues like clogged toilets can occur from time to time. However, if the clogs are occurring on a weekly or daily basis, or if they have occurred in several fixtures in the home, it is time to invest in total drain line cleaning services.

Another sign of a drain issue is if water has started to bubble up from the shower drain when the toilet is flushed. If situations like this occur, it means there is too much air in the drain system.

This is another sign that it is time for drain cleaning or drain service from a professional plumber.

If there are strange pools of putrid water in the yard, this is a sign of a serious plumbing problem. This may require drain cleaning services, or it could be so severe that sewer line repair is required.

Basements aren't always waterproof. However, if a homeowner's basement is typically dry and they begin to see water stains in this part of their home, it indicates that sewage may be backing up.

This usually occurs because of inadequate drainage. If this is seen in any house, it is time to take action.

A professional plumber will be able to determine the underlying issue and make the needed repair. They may also be able to find smaller problems that a homeowner was not aware of and make repairs before they get worse and cause more problems.

The key is to call in a timely manner and never put off the repairs that are needed.
