Does Toilet Flange Go Inside Pipe? (Solved)

The toilet flange is an essential component when it comes to your plumbing and how the toilet settles into the bathroom.

Unfortunately, having the toilet flange in the wrong spot can lead to serious issues including a wobbly or leaky toilet.

To avoid this, you will want to figure out how a toilet flange is supposed to be installed and what to look out for. This includes asking, does a toilet flange go inside the pipe?

A toilet flange does go inside the pipe. It should be glued to the inside of the pipe to ensure it does not budge once the toilet is installed on top. When set up, the toilet flange should be flush with the floor.

Attempting to install it to the outside of the pipe will create an imbalanced look that will not work for your toilet.

This is why it’s important to make sure the toilet flange goes perfectly into the pipe and is then glued to the fixture.

This article will pinpoint what you should be focusing on when it comes to installing a toilet flange inside the pipe.

How To Install Toilet Flange Inside A Pipe

1. Clean The Inside Of The Pipe

To get started, you will want to clean the inside of the pipe.

This is to prep it for the glue and to make sure the new toilet flange fits. If not, you will have to modify the pipe to make sure it is a perfect fit when the toilet flange is installed.

If the pipe is not the right size, take a PVC pipe cutter drill bit and begin drilling in a circular motion to widen the hole. This will allow you to get into the pipe and make it wider for the flange.

Once everything is the right size and as clean as it can be, you will want to start moving forward with the gluing process.

2. Apply Glue To The Sides Of The Pipe

The glue is an intricate part of the process.

In general, you will want to take the glue and spread it across the side of the pipe and the toilet flange.

This will ensure it settles nicely into place and allows you to fit it correctly. Be careful while doing this and make sure not to spread the glue to the outside part of the pipe.

This will leave a residue you don’t want to have to clean afterward.

Be patient and apply the glue until it is fully lathered into place. This is what will hold the toilet flange in place and keep the toilet sturdy when it sits on top.

3. Push Flange Into The Pipe

You are now going to push the flange into the pipe.

Be careful while doing this and make sure it goes in straight. This is to ensure the toilet flange does not leave gaps.

This is how leaks occur.

Push the toilet flange in and make sure it is sitting flush with the floor. There should be no gap between the sides of the toilet flange and the flooring.

When you are sure it is in properly, it is time to let it sit.

4. Let The Flange Dry For 4-5 Hours

The drying phase is important.

You don’t want to start installing the toilet right away assuming the toilet flange is now good to go. There is a waiting period and you will have to let it complete before moving forward with the process.

How long should you wait?

Installing the toilet flange inside the pipe is important but this phase is critical too. You will want to wait at least 4-5 hours for the toilet flange to settle.

If you put the toilet on top too early, it will cause the flange to shift. This is the last thing you are going to want, which is why waiting is key.

Final Thoughts

Does a toilet flange go inside the pipe?

A toilet flange always goes inside the pipe. To do this, glue the toilet flange into the pipe to make sure it holds and remains sturdy. If not, the toilet can become wobbly and/or leaky.

It is important to take your time with this process and prep the pipe. This includes widening it if the toilet flange does not fit.

Each step in the process is key.

This includes how the glue is applied, where the glue is applied, and how the toilet flange is pressed into place. If it is too high, the toilet will become increasingly wobbly and difficult to use.
