Lowering the toilet flange on a slab is possible but it can be quite difficult. It’s recommended to only attempt this kind of project if you have some plumbing experience. The first step is to remove the toilet from the existing flange.
This can be done using a plunger and some WD-40 to loosen the bolts. Once the toilet is removed, you’ll need to remove the existing flange, which can be done by unscrewing the screws and removing the brass ring around the flange.
Next, take a grinder to lower the concrete slab. This should then reveal a path for the new toilet flange to be inserted. Carefully measure where the flange should go and mark the spot. Then, use a hammer to break through the slab where the flange will be placed.
Once you’ve created the area, you’ll need to measure the depth of the flange and cut down a piece of pipe to roughly the same depth. Place the pipe into the hole you’ve created and then use a silicone sealant to make sure it’s securely in place.
Place the new flange over the pipe and use screws and a wrench to secure it to the concrete. Finally, reattach the toilet and you should be finished!.
How do you fix a toilet flange that is too high in concrete?
If you have a toilet flange that is too high in the concrete, there are a few steps you can take to try and fix the problem. The first step is to chip away at the concrete around the flange to reduce its height.
You will need to use a chisel and hammer to carefully chip away at the concrete until it is roughly level with the floor. Once you have done this, you may need to use some self-leveling caulk around the edge of the flange to further reduce its height.
This should allow it to seat correctly. If the flange is still too high after this, then you may need to use a toilet flange extender to bring it up to the correct height. This is a plastic ring that fits over the toilet flange and can be screwed down to secure it in place.
Once you have the flange to the correct height, you can then secure it in place using a wax ring and the standard screws that secure the flange to the floor. If you find it difficult to secure the screws due to the thickness of the concrete, then you can use concrete screws instead.
Hopefully, with these steps, you should have fixed the problem with your toilet flange that is too high in concrete.
How do you change toilet flange height?
Changing the height of the toilet flange is typically done when replacing the old flange due to wear or damage, or when installing a new toilet in an area where the existing flange height is not compatible with the new toilet.
In order to change the height of the toilet flange, you will need to first turn off the water supply to the toilet. Then, use a screwdriver or other tool to loosen the screws that are holding the flange onto the floor.
Once the screws are removed, the flange should be easily lifted up from the drain pipe.
Once the flange is removed from the drain pipe, you should measure the height of the pipe using a ruler or tape measure. This will tell you how much you will need to adjust the new flange when you install it.
If you need to increase the height of the flange, you can do this by purchasing spacers or extensions that will fit on top of the flange. These spacers can be found at most home improvement stores.
In order to install the new flange, you will want to place a layer of plumber’s putty around the outside of the new flange. Then, slide the flange over the drain pipe, ensuring that the connections fit tightly.
Next, you will want to attach the flange to the floor using the screws that came with it. Finally, turn the water supply back on and test the toilet to ensure that it is working correctly.
Changing the toilet flange height does not need to be a complicated process, but it should be done carefully by following the proper safety and installation instructions.
Should toilet flange be flush with concrete floor?
Yes, the toilet flange should be flush with the concrete floor. This is because the toilet flange is used to link the toilet to the drainpipe and it needs to be level to sit securely. If the toilet flange is not flush with the concrete floor, then there will be a gap between the two and the toilet may not sit properly or may become loose, potentially leading to water damage.
When installing the toilet flange, it’s important to use a level to make sure that it is fully flush with the concrete floor. The toilet flange should also be properly secured with screws and a seal to make sure that it is secure and won’t come loose.
Can you reposition a toilet flange?
Yes, you can reposition a toilet flange if needed. To reposition a toilet flange, you need to first remove it from the floor and cut off any caulking from the old flange. You will then need to measure and mark a spot for the new flange and use a hole saw to cut the new hole for the flange.
Next, you will fit the flange into the new hole and use a wax ring to attach the flange securely to the floor. After the flange is in place, you will need to measure and cut the PVC pipe to fit the new configuration.
Finally, you will need to secure the flange and connect the toilet to the new plumbing.
Should toilet flange be above or below tile?
The best approach is to install the toilet flange so that it is slightly above the tile flooring. This allows the wax ring of the toilet to properly seal off the drain, which is essential for proper function.
Additionally, the floor needs to be perfectly level for the wax ring to provide a tight seal. If the flange is below the tile, it will be difficult to see if the floor is level or not, thus making it difficult to create a watertight seal with the wax ring.
It is also important to make sure the flange is sitting squarely against the floor, as uneven resting points can also lead to a poor seal.
How high can a toilet flange be off the floor?
The height of a toilet flange can vary between 1/4 inch and 1 1/4 inches off the floor. The definitive height for a toilet flange is determined by the toilet model, the size and shape of the pipe, and the mechanical needs of the installation.
Ultimately, the height of the flange is driven by the installation requirements of the toilet, so it is important to read the manufacturer’s instructions for the selected toilet before beginning installation.
It’s important to note that installing the toilet flange at the correct height is essential for a successful installation; the toilet needs to sit securely on the flange so there is no leakage or challenge with water pressure.
As a result, it is advisable that the height of the flange is kept as close to the specified height as possible. Additionally, don’t forget to double check the flange height after the toilet is installed to ensure nothing has changed.
Installing the toilet flange properly will help to keep the bathroom clean and free of irritating odors.
Does floating floor go under toilet flange?
No, floating floor should not be placed under the toilet flange. The toilet flange has to be securely mounted and attached to the subfloor so that it won’t move. The flange must be sitting on the subfloor and the subfloor should be screwed into the joists, so a floating floor will not be able to provide the stability required for a secure fitment.
A floating floor is one that is not connected to the subfloor, allowing the flooring to move up and down more freely- thus, it is better suited for an area such as a living room or bedroom.
How do you level a toilet on a concrete floor?
When installing a toilet on a concrete floor, it is important to make sure that it is levelled so that when it is in use, it has the correct pitch towards the drain, thereby allowing the wastewater to flow properly.
To level the toilet, you will need two adjustable wrenches, one that fits the bolts that hold the toilet in place, and one for the metal shims. To begin, turn off the water supply to the toilet, and flush the toilet to empty the tank.
With the adjustable wrench, turn the bolts that hold the toilet down slightly and remove the toilet. It is recommended to remove the wax ring underneath the toilet, as well.
Next, place the appropriate number of metal shims around the perimeter of the toilet flange, equidistant from each other, to create a level base. Tap each shim with a hammer to ensure they are even. Place the toilet back down over the shims, ensuring that the bolts are centred in the slots in the flange.
With the adjustable wrench, tighten the bolts until they are slightly sticking out of the slots.
Now it’s time to test the level. To do this, you will need a spirit level, the smaller bubble is more accurate. Place the level onto the sides, top and bottom of the toilet. If the bubble shows differently than the level line, then adjust the metal shims and/or bolts to even it out.
When you have achieved a level, with all four bubbles sitting over the centre line, it is recommended to then add some more silicone caulking around the base of the toilet to prevent any water from leaking underneath.
Finally, turn on the water supply and test that the toilet is functioning correctly.
What if my toilet flange is not level?
If your toilet flange is not level, then it can cause a number of issues. A toilet flange needs to be level in order for the toilet to be securely bolted to the floor. If the flange is not level, it can cause the toilet to wobble, creating a faulty seal and allowing water to leak.
It can also lead to the toilet being misaligned, and can make the entire installation very unstable.
If you discover that your flange is not level, you can use a spirit level or a straight edge and shims to correct it. Depending on the level of damage and how badly the flange is warped, you may need to replace it, rather than just shimming it.
You can also use a toilet flange repair kit to fix minor damage. Whatever the approach, it’s important to make sure that the flange is fully secure and level before moving forward with installation.
How high is too high for toilet flange?
When it comes to toilet flange installation, the ADA (Americans with Disabilities Act) states that the flange should be no higher than 1/2” above the finished floor. Typically, a toilet flange should ideally be flush with the floor.
A flange that is too high will prevent the toilet from sitting correctly and the toilet will move or rock. This can cause leaking, which can damage your flooring and even result in costly repairs. Additionally, if the toilet flange is too high it can cause the wax gasket to seal improperly, which will also create a leaking or seeping issue.
As a general rule of thumb, when installing a toilet flange, measure the height and ensure that it is no higher than 1/2” above the finished floor.
Can toilet flange be too high?
Yes, a toilet flange can be too high. If the flange is too high, the seal between the toilet bowl and the drainpipe will not form correctly, and the toilet is likely to leak or overflow. Additionally, if the toilet flange is set too high, the toilet will not seat properly and can cause damage to the bottom of the toilet bowl.
It is important to make sure the toilet flange is level with the floor, as it can cause costly problems if it is installed at the wrong height.
Should you caulk around toilet flange?
Yes, caulking around a toilet flange is an important part of keeping a bathroom and its plumbing in good condition. Caulk is a waterproof sealant that prevents water from getting between the flange and the floor, which could eventually lead to water damage.
Properly caulked toilet flanges also ensure that no smells or moisture escape from the bowl. Caulking a toilet flange is not hard, but it does require the right materials. First, you need to make sure that the surface of the flange is clean and dry so that the caulk will adhere properly.
Next, you’ll need to choose the right kind of caulk, and make sure it is designed to resist mildew. Once the caulk is applied, use a wet finger to smooth it out and create a neat, consistent seal. Finally, it’s important to wait for the caulk to dry completely before you run water or use the toilet.
With proper caulk and care, your toilet flange will keep your bathroom functioning well and prevent water damage.
Does toilet flange have to be glued in the pipe?
In general, no, a toilet flange does not have to be glued in the pipe. Typically, the toilet flange is installed first and then there are bolts that are inserted through the toilet flange and tightened down to secure the flange in place.
This is done when the toilet is first installed, which allows the toilet to be completely sealed from any leaks from the floor of the bathroom. Depending upon the type of pipe the toilet flange must be attached to, sometimes a sealant or glue can be used to help secure the toilet flange or to help prevent any seepage of water from around the flange.
However, this depends on the type of pipe being used and is not always required.
Do you have to screw the toilet flange to concrete floor?
Yes, it is necessary to screw a toilet flange to a concrete floor in order to properly install the toilet. A toilet flange acts as a connecting point between the toilet and the drain pipe. It is designed to fit over the top of the drain pipe and create a secure connection.
When attaching the flange to a concrete floor, it is best to use specific anchors and screws that are designed to work with concrete. The screws need to be long enough to penetrate through the concrete and into the joists below.
Additionally it is important to make sure that the flange sits squarely against the concrete in order for it to create a good seal. Once the flange is properly secured and sealed, the toilet can then be installed on top of it.
