When installing a new toilet, the flange must be level to ensure a proper seal. If the flange is not level, the toilet could leak water or, worse, break loose and cause a flood. 

Here are some tips on checking your toilet flange for levelness and adjusting it if necessary.

What is Toilet Flange?

A flange is a projecting rim, collar, or edge around or near the open end of a pipe, fitting, or other objects, holding it in position or strengthening it. 

Flanges are commonly used to connect two pipes or to attach a pipe to a fitting. When welding or bolting a flange to a pipe, care must be taken to ensure that the flange is positioned correctly. If the flange is not aligned properly, it can cause a leak.

Why is the toilet flange not even with the floor?

Sometimes bad construction causes either the toilet flange to be too low or too high. There are a few reasons for the toilet flange is not even with the floor.

No1. reason for toilet flange not even – Not Evenly Distributed Slab

When the slab was poured, the contractor may not have compensated for the thickness of the flange, or there may have been some settlement since then. 

No.2 reason for toilet flange not even with the floor- The Hole of the Floor

The hole in the floor could also be too big or off-center, which would throw off the alignment. If your toilet wobbles, it’s likely that the flange is too low or high and needs to be adjusted.

No3. Cause for Flange is not Even – Toilet is not Centered.

Another possible reason your toilet flange might not be even with the floor is that your toilet may not be properly centered. 

When your toilet is installed, the installer should measure from the center of the drainpipe in the wall to the center of the bolts on the floor that hold your toilet in place. 

If those measurements are off, your toilet may not be sitting squarely on top of your flange, which could cause it to wobble or, even worse, leak.

No4. Possible Cause, not even a Toilet Flange is- A Warped Floor.

Another possibility is that you may have a warped floor. In this case, you would need to have a professional fix it before installing your new toilet. 

Monitoring the floor for any movement or warping is important when installing a new toilet. If you notice that there are signs of distress, get in touch with someone who can fix it before installation!

If you’re uncomfortable doing this job yourself, you can call a plumber to do it for you. They’ll likely adjust the flange by welding on a new piece of metal or by removing a layer. 

Whichever method they choose, it’ll likely cost you around $200( may vary from region to region.)

toilet flange need to be level

Does the toilet flange need to be level with the floor?

Yes. The Toilet flange needs to be level, and it’s essential so that the toilet can sit properly on top of it. If the flange is not level, the toilet may wobble or even fall off of the flange.

A toilet flange needs to be even with the floor because off-level flanges can cause leaks even; the uneven flanges can lead to the toilet cracking from the baseline.

What if my toilet is not level?

If the toilet is not level, it can cause problems with the plumbing. If the water leaks out of the tank and onto the floor, it can damage the floor and seep into the floorboards.

How do you fix a misaligned toilet flange not level with the floor?

There are a few ways to fix a misaligned toilet flange.

Trick1. Using Shims

If your toilet is not level, you can use shims to level it. Shims are thin pieces of wood or metal that you can place under the toilet to make it level.

You can either buy a shim at a hardware store or cut one from a piece of wood. If you choose to cut your own shim, make sure it is thin enough to fit under the flange and wide enough so that it will not move once it is in place.

Once you have your shim, place it under the flange and use a hammer to tap it into place. Make sure the shim is level with the floor before you tap it in. 

You can use a spirit level or a straight edge to check this. If your flange is still not level, you may need to add more than one shim.

Once the shim is in place, re-attach the toilet flange to the toilet. 

If the flange is too high, you can lower it by adding shims between the flange and the floor. If the flange is too low, you can raise it by removing shims from between the flange and the floor.

Trick2. By adjusting the Screws

You can also adjust the height of the flange by adjusting the length of the screws that hold it in place. If the screws are too long, you can shorten them by removing the washers from the top of the screws. 

If the screws are too short, you can lengthen them by adding washers to the top of the screws.

If you are using an old flange, use the screws that were originally used to attach the flange to the toilet. 

If these screws are no longer available, use some plumber’s putty to attach the flange to the toilet.

For a wax ring:

Put the wax ring on the toilet flange and then place the toilet on the ring. Make sure the toilet is centered over the flange. 

Use your hand to press down on the top of the toilet to compress the wax ring. Then use your other hand to tighten the screws that attach the toilet flange to the toilet.

For having no Wax ring:

If you do not have a wax ring, put some plumber’s putty around the edge of the toilet flange. Then place the toilet on the flange. Make sure the toilet is centered over the flange. 

Use your hand to press down on the top of the toilet to compress the plumber’s putty. Then use your other hand to tighten the screws that attach the toilet flange to the toilet.

To fix the problem, you can put a shim under the front of the toilet to raise it up. Make sure that the shim is the same thickness as the toilet’s base and that it is wide enough to cover the entire base. 

You can also use a piece of wood or a stack of books to raise the front of the toilet.

Trick4. Adjusting the Toilet flange on the angle

If the toilet flange is not level with the floor, you can fix it by adjusting the angle of the flange. If the flange is too high, you can lower it by angling the flange down. If the flange is too low, you can raise it by angling the flange up.

You can also adjust the angle of the flange by adjusting the length of screws that hold it in place. If the screws are too long, you can shorten them by angling the screws down. If the screws are too short, you can lengthen them by angling the screws up.

Ensure that the new drain is level with the floor and diameter matches the flange, and is installed at the correct height. If the drain is not level or if it is installed at the wrong height, you may need to replace it.

Option3. Is to use a flange extender.

If you choose to use a flange extender, make sure that it is the correct size and properly secured to the flange.

Option4. Adjustment of Shim

If the toilet flange is flush with the floor, you may need to adjust the shims until the flange is level with the floor. If it does not, you may need to adjust the shims until the flange is level with the floor. If it does not, you may need to replace the flange.
