Find out more about the benefits of plumbing cleanouts below and why your pipes should regularly be checked to avoid blockages. 

What Are Plumbing Cleanouts?

Plumbing cleanouts allow plumbers to access the home sewer pipe that then leads into the main sewer.

This allows them to see if anything is clogging the pipe that is preventing waste from going towards the main sewer pipe, so having a regular plumbing cleanout or check is important to prevent any clogs or blockages. 

Therefore, your pipes need to be checked to make sure that there are no blockages that are affecting your waste going into the main sewer pipes.

A blockage will then affect your home, so it must be fixed. If the blockage remains there, it will continue to build up and it will become more difficult to remove, so it must be sorted. 

What Are The Types Of Plumbing Cleanouts?

It is important to know the different plumbing cleanouts as they indicate where the plumbing cleanouts are placed around your home.

You should be aware of where they are placed as you should know how to access them if there is a problem or if a plumber needs to check.

Inside Cleanouts

Inside cleanouts are found inside homes in particularly cold areas, and they are usually found in basements.

They are found inside as the cold can freeze them over and make them very difficult to get into, so it is important to make sure that they are accessible.

As the main drainpipe is upright, the inside cleanout is often joined up to it. 

Outside Cleanouts

Outside cleanouts are often found outside of homes, especially in warm areas.

They are often connected to the main sewer and they can sometimes be difficult to locate if you are unfamiliar with them.

They are usually found as a pipe coming out of the ground, and they can have blockages removed.

Drain Cleanouts Indoors

Inside cleanouts are often found next to sinks, showers, and baths, as they all have plumbing traps.

The plumbing traps are shaped like a ‘U’, so it is very easy for clogs to occur as things can easily get stuck in the bottom of the ‘U’ shape.

Cleanouts are placed near the plumbing traps to make sure that you can easily access them and clear the pipe of clogs.

3 Main Types Of Plumbing Cleanouts

There are 3 main types of plumbing clearouts to be aware of and understand.

Here are the main plumbing cleanouts that you need to know about.

Single Cleanout

When referring to a single cleanout, it means that there is only access one-way into the sewer line going in one direction.

There isn’t direct access to the pipe, and it all depends on the angle of how you can access the pipe. 

Double Cleanout

A double cleanout refers to how the pipes are connected and how they are connected to the main drain.

There is access from both directions and it is the most popular cleanout as it is easier to access. 

Test-Tee Cleanouts

The test-tee cleanouts are very similar to double cleanouts as they allow accessibility at both ends of the main drain pipe.

The pipes are shaped like a ‘T’, but they are very difficult to clean out and remove blockages from due to their 90-degree angle. 

How To Find A Plumbing Cleanout

You can easily find a plumbing cleanout by looking for a large pipe that is above the ground.

You can identify the plumbing cleanout by looking for the large pipe that has a square cap made from metal, and it is usually located by your home or in your backyard. 

If you are living in a colder area, you might find that your plumbing clearout is located in your bathroom or your basement.

It will look the same, it will just be in a different location to protect it from becoming frozen by the cold temperatures. 

It is important to know where your plumbing cleanout is located if you find yourself experiencing a blockage.
