You can't see it, or feel it, but the main sewer line -- which transports wastewater out of your home -- is far more important than you think. When this sewer line becomes clogged, it can cause all sorts of problems, which is why regular plumbing maintenance is crucial.

Here are some of the telltale signs that the main sewer line has become blocked.

1. Your Washing Machine Overflows

If your washing machine suddenly overflows, it might not be a problem with the machine itself but a blocked main sewer line, which is unable to transport wastewater properly [1].

What can you do about this? Contact a plumber immediately. Waste pipe blockages can get worse over time, which will only increase repair costs when you do finally address the problem. Alternatively, invest in a protection plan and identify problems with your sewer system ahead of time for even more cost savings.

2. Your Bathtub Fills Up With Water

Imagine the scene: You get home from work and it seems like someone has run you a bath. But there's nobody in the home. Scary, right?

A blocked main sewer pipe could be the culprit here, but it's best to enlist the services of a qualified professional plumber to make sure. In many cases, the main sewer line that transports wastewater from your bathroom becomes clogged, which causes your tub to fill up [2].

3. Your Toilet Makes a Strange Noise

Hear a strange noise when you flush the toilet? It sounds like something from a horror movie -- a frightening, gurgling sound that sends a shiver down your spine.

Strange noises coming from your toilet could mean that the main sewer line has become clogged -- and you need to take action immediately.

Other telltale signs of a blocked main sewer line include overflowing toilets and toilets that don't flush properly. In both of these circumstances, it's best to call in an expert. Benjamin Franklin Plumbing has all the tools and techniques to make repairs to sewer lines.
