How to Find Your Sewer Line

how to find your sewer line

Your sewer line is an integral part of your home’s plumbing system. It is responsible for carrying waste water away from your home and into the municipal sewer system.

Therefore, it is important to know where your sewer line is located in case you ever need to repair or replace it.

Luckily, finding your sewer line is not as difficult as you might think. In this blog post, we will show you a few simple steps that you can follow to find your sewer line and keep your home’s plumbing system running smoothly.

Step 1: Locate Your Home’s Main Shut-Off Valve

The first step in finding your sewer line is to locate your home’s main shut-off valve. This valve is typically located in the basement or near the water meter.

Once you have found the main shut-off valve, turn it off so that you can work on the plumbing without water flowing through the lines.

Step 2: Find the Clean-Out Plug

The next step is to find the clean-out plug. The clean-out plug is a threaded cap that is used to access the clean-out fitting.

This fitting is used to clean out clogs in the sewer line. The clean-out plug is usually located near the main shut-off valve or near the water heater.

If you cannot find the clean-out plug, look for a clean-out fitting that has a square or rectangular cover plate.

The cover plate will be screwed into place and will need to be removed before you can access the clean-out fitting.

Once you have found the clean-out plug or fitting, use a wrench to remove it so that you can access the clean-out fitting.

Step 3: Use a Sewer Snake to Locate the Sewer Line

Now that you have access to the clean-out fitting, it’s time to use a sewer snake to locate the sewer line.

A sewer snake is a long, flexible cable that is inserted into the clean-out fitting and fed through the drainpipe until it reaches the clog.

To use a sewer snake, first, insert the cable into the clean-out fitting and then turn on the power (if it’s an electric sewer snake).

Then, feed the cable through the drainpipe until you feel resistance. This resistance is likely caused by the clog at the end of the pipe.

If you encounter any resistance while feeding the cable through the pipe, turn off the power and try again later.

After a few attempts, you should be able to feed the entire length of the cable through the pipe and reach the clog.

Finally, once you have reached the clog, use back and forth motion to break it up so that it can be flushed away with water.

If you cannot break up a clog on your own, you may need to hire someone who can do it for you professionally.

How To Find Sewer Line Under Concrete Slab?

There are a few different ways that you can find your sewer line if it’s hidden under a concrete slab. One way is to look for an access hole in the ground that leads to the sewer line.

These access holes are typically located near the street or sidewalk. If you see an access hole, you can use a garden hose or plumber’s snake to try and clear any blockages in the line.

Another way to find your sewer line is to look for any changes in the level of the ground around your home.

If there are any sudden changes in elevation, this could be an indication that there is a break in the sewer line.

You should also look for any cracks in the foundation of your home, as this could also be an indication of a problem with the sewer line.

If you see any of these signs, it’s important to contact a professional as soon as possible so they can determine the extent of the damage and make the necessary repairs.

How Many Sewer Lines Does A House Have?

So, how many sewer lines does a house have? The answer depends on a few different factors, including the size of the house and the type of sewage system it uses.

Most homes have either a single or dual sewage system. A single sewage system has one pipe that carries both wastewater and rainwater away from the house.

A dual sewage system has two pipes - one for wastewater and one for rainwater.

The size of the house also affects the number of sewer lines. A small house with only one bathroom will need just one pipe, while a larger house with multiple bathrooms will need multiple pipes.

The number of appliances in the home that use water (such as washing machines and dishwashers) can also affect the number of pipes needed.

How do I find a sewer line in my yard?

The first step is to contact your city or county government office. They will be able to provide you with a map of the sewer lines in your area.

Once you have the map, take a look at it and see if you can identify where the line is in relation to your property.

If you’re having trouble finding it, then you can also try looking for manhole covers. These are typically located at the edge of properties, near sidewalks or streets.

If you’re still having trouble finding the sewer line, then you can always hire a professional plumber to come out and take a look.

They will be able to locate the line and give you an estimate for any repairs that may need to be made.

How Deep Are Sewer Lines?

The average depth of a sewer line is between 12" to 30" or as deep as 6ft. However, there are some homes with shallower lines and some with deeper ones.

The depth of your sewer line will be dependent on a few different factors, including the type of soil in your yard and the location of the line in relation to your home.

For example, if you live in an area with clay soil, your sewer line will likely be shallower than if you live in an area with sandier soil. This is because clay soil is heavier and denser than sandier soil, so it doesn't settle as much over time.

Additionally, if your sewer line runs underneath your driveway or another hard surface on your property, it will also be shallower than if it were running through your front yard.

Conclusion

Finding your sewer line is not difficult if you know where to look and what tools to use to follow it.

By locating your home’s main shut-off valve, removing the clean-out plug or cover plate, and inserting a sewer snake into clean to access and clear any clogs, you can keep your sewer line in good working order for years to come.
