Here’s how to fix broken sewer pipe under house, follow these steps:
Step 1: Identify pipe damage.
If you are not sure where the broken pipe is, or if there’s more than one broken or leaking pipe, use a camera to take pictures of the damage. If you have an underground camera, that can help too. For instance, if it is a blockage and not a leaky pipe, then your best bet would be to use an auger machine to clear out any clogs in your pipes before attempting repairs on them.
And now that we know what type of repair job we’re dealing with (a leaky pipe), let’s look at some other common problems associated with this issue:
Step 2: Dig around the sewer line.
The second step in repairing your broken sewer pipe is to dig around the pipe. You need to remove any debris that has accumulated around it, and you should also inspect its condition. If a crack, hole or other breakage is present in the pipe itself, then you will have to cut out a section of it and replace it with new PVC pipe.
Once you’ve dug out any dirt or other materials from around the area where your sewer line runs under ground (using a shovel), use a spade to carefully dig down about two feet below ground level so that you can see where exactly the end of your sewer line is located.
Step 3: Find pipe leaks.
The next step is to locate the leak. If you are not sure where it is, use a sewer line leak detection tool such as an electronic locating device, video camera or dye test.
An electronic locating device can be used by following these steps:
- Attach the locator to your existing sewer pipe and turn it on. The locator will emit a signal that travels through your pipes and will detect any leaks in their path. You can then trace back from where they were found (in this case, directly under the house) until they reach their origins at your toilets or sinks – which is where the water may be coming from! This works especially well if there are multiple leaks in one area: since they all share a common source point (your toilet), you can easily pinpoint which one has caused this mess!
Step 4: Remove damaged section of pipe.
Remove the damaged section of pipe by cutting it with either a hacksaw or reciprocating saw. Once you have removed the damaged section, use a chisel to remove any remaining pieces of pipe.
Step 5: Cut a new length of pipe.
- Cut the new length of pipe to the correct length with a hacksaw.
- Ensure that you have the correct tools for cutting PVC piping and fittings, including blades for your saw, measuring tape, pencil and pliers.
- Make sure you have enough pipe to complete the job. A good rule of thumb is to add five percent extra length per fitting or joint in case something goes wrong during installation.
- Check that you have enough pipe to be able to re-bury your connection after testing it by following Step 6: Connect And Test Your Sewer Pipes Under House
Step 6: Prepare new pipe for installation.
Prepare the new pipe for installation by using a hacksaw to cut it to length. Then use a hammer and chisel to remove old pipe from the walls of your house.
Clean out the sewer pipe before installing new PVC pipe by drilling holes in it, then flushing out the debris with water from your garden hose.
Step 7: Join new pipe with old pipes.
Once the new pipe is in place, you will need to join it with the existing pipes. Here are some of the ways you can do that:
- Use a coupling to join them together. This method is most commonly used when joining PVC pipes together because it creates a waterproof seal between the two pipes. You can buy them at any hardware store or home improvement store, but they are also pretty easy to put together by hand if you want something cheaper and more custom made.
- Use PVC primer and cement to create a permanent connection between your old and new pipes. This option is best for people who have experience using this type of product because it’s important that everything dries properly before using your sewer line again so there aren’t any leaks anywhere along its length.#ENDWRITE
Step 8: Re-bury the sewer line pipes and test the connection.
Once you have the pipe in place and buried, it’s time to test your work. First, make sure that the new pipes are connected to both the old pipes and to each other. If there is any damage or weakness in either of these areas, you need to repair or replace those sections before continuing on with this process.
Next, make sure that all parts of your new system are buried deep enough so they won’t be damaged by digging equipment or accidentally stepped on by someone walking near them. When finished burying your sewer lines back into place, fill up any holes with dirt and tamp them down firmly until smooth again.

You will need:
- Plumber’s snake, ratchet and socket
- New sewer pipe section
- Hammer chisel and/or sawzall (depending on your type of pipe)
Fixing broken sewer pipes can be challenging but can be accomplished with great effort.
When broken sewer pipes occur, the pipe must be replaced and connected to the existing pipe. The new pipe needs to be buried underground after the connection is made.
In conclusion, there are a few ways to fix a broken sewer pipe. It may be difficult but with the right information and equipment you can do it yourself.
