Replacing a toilet flange on a concrete slab can be a tedious and difficult job. First, you will need to turn off the water to the toilet and detach the supply line. Then, you will need to remove the old flange by gently prying it up with a scraper or utility knife.
Be careful not to create too much damage to the concrete. Once the old flange is removed, you will need to use a 4″ hole saw to cut a new mounting hole in the concrete slab, then place a new wax ring over the outlet pipe and position the flange where it needs to go.
Make sure the flange is level and secure it with the proper mounting screws. Once the flange is firmly secured, replace the supply line and turn the water back on. Lastly, reattach the toilet to the flange, making sure to use new bolts and washers if the old ones are rusted or damaged.
Finally, test the toilet to make sure it is properly sealed and the flange is secured.
Should toilet flange be screwed to concrete floor?
Yes, toilet flanges should be screwed to the concrete floor. This is done to ensure that the flange remains firmly in place. Toilet flanges are metal rings that are placed on the floor around the hole that is cut into the ground for the toilet.
These flanges create an airtight seal between the toilet and the floor. Without the flange being securely attached to the floor, it may move or shift over time. This can cause leakage or other issues resulting in the need for the flange to be replaced.
Screwing the toilet flange to the concrete floor is the best way to ensure that it remains firmly in place. For best results, use lag bolts or concrete anchors when doing this. It is also important to ensure that the flange is level which can be done with a spirit level.
Additionally, make sure that the flange is not screwed in too tightly as this can lead to cracking or warping.
Do you need a plumber to replace a toilet flange?
Yes, it is best to have a qualified professional plumber to replace a toilet flange. A toilet flange is a pipe fitting that sits underneath the toilet, connecting the toilet to the floor and the drain pipe.
This can be a delicate job, because if the toilet flange is not correctly replaced, it can lead to the toilet becoming loose, leaking, and eventually coming off the floor. Furthermore, a faulty installation of the toilet flange may lead to potential water damage, which is why it is advised to use a qualified professional when installing a toilet flange.
A professional plumber will be able to determine if the necessary repairs can be done safely, as well as measure and cut the pipe to the correct size for a secure installation. In addition to cutting and fitting the pipe properly, the plumber can check for any other issues that may have been missed or neglected and ensure the installation is done properly and the toilet is securely held to the floor.
Plumbers may also be able to provide information on other fixtures and parts to help ensure the best long-term success for the replacement of the toilet flange.
Does toilet flange sit on concrete or tile?
The answer to this question depends on the setup of the flooring in the bathroom area. Generally, a toilet flange is installed on top of a concrete slab since it is more durable, but it can also be installed on top of a tiled floor.
When installing a toilet flange on a tiled floor, extra caution must be taken. The most important factor is to make sure the tile and mortar are securely attached to the subflooring. This ensures that the flange is well-supported when there is pressure exerted on it, such as when someone sits on the toilet.
It is also important to ensure that the tiles are properly sealed so that water does not get underneath and cause problems like mold growth or structural damage. Once it has been securely installed, the toilet can then be connected to the flange.
Should toilet flange fit inside or outside pipe?
When installing a toilet flange, it generally should fit inside of the pipe. The toilet flange should normally sit atop the existing pipe and be fastened with screws into the floor. When the floor flange is correctly installed, the bolts that join the flange to the toilet should rest at the same level as the floor.
If the flange does not fit properly within the pipe, the toilet will be incorrectly installed and could become loose and create a potential leak. To avoid this, measure the diameter of the flange before purchasing and make sure it fits snugly and securely within the pipe.
Additionally, it’s important that you make sure the toilet flange is properly positioned before screwing in the screws.
Does tile go under the toilet flange?
The short answer is yes, tile should go under the toilet flange. To properly install tile around a toilet, it is best to use a thinset mortar bed to secure the tile and create an even surface. Before installing the mortar, you must install a waterproofing membrane underneath the flange to prevent moisture and water damage.
Once the membrane is in place, the mortar should be applied next, followed by the tile. The mortar should be allowed to dry and cure before continuing with the installation. Once the tile is in place, the flange should be installed last to ensure a proper seal.
Make sure the flange is level with the tile and ensure there are no gaps between the flange and the tile. Any gap can cause a leak. Follow any additional installation instructions that come with the flange for a correct and secure installation.
How high can a toilet flange sit above the floor?
The height between the bottom of a toilet flange and the floor can vary depending upon the type of plumbing installation and the flange itself. Generally, the maximum height of a toilet flange should not exceed 1/4″.
However, some local codes may vary from jurisdiction to jurisdiction, so it’s important to check with your local authority to ensure that your plumbing installation meets all applicable codes. In addition, the height of the toilet flange will also depend upon the type of flange you are using; some types are designed to sit higher off the floor than others.
Additionally, for some installations, it may be necessary to adjust the flange height to ensure proper drainage and to prevent shared-vent issues. It’s important to mention that unevenly-set flanges can cause the toilet to rock and result in premature leakage and other water damage, so it’s important to ensure that all measurements and installations have been correctly performed.
How much does a plumber charge to change a flange?
The cost of having a plumber change a flange can vary depending on the type of flange required and the location of the flange being replaced. On average, a qualified plumber may charge between $120 and $180 to remove and install a new flange, including an estimate for all necessary supplies.
The cost may be higher or lower depending on the complexity of the job and other factors. For instance, if the flange needs to be connected to a complex plumbing system, the cost may be higher due to the additional time and materials required to complete the job.
Additionally, if the plumber needs to make any repairs or replacements to existing pipes or fixtures, this may add to the total cost as well.
Can you put a new toilet flange on top of an old toilet flange?
It is not recommended to put a new toilet flange on top of an old one. Toilet flanges are designed to hold the toilet in place, and if you place one toilet flange above another, it creates a precarious and unstable situation.
Not only could this potentially damage the toilet and flange, but it could also lead to an improper seal, resulting in leaking or other issues. Additionally, if you stack the flanges, it will make it difficult to obtain a proper installation with the wax ring and bolts.
For these reasons, it is better to remove the old flange and replace it with a new one.
What screws for toilet flange to floor?
In order to secure the toilet flange to the floor, you will need to use screws. The type of screws that you should use will depend upon the material of the floor and the flange. It is recommended that you use bolts and nuts to secure the flange to the floor.
There are a few basic steps to install these bolts:
First, the flange should be centered over the hole in the floor. You will then need to insert the bolts through the holes in the flange and into the floor. Once this is done, it is important to make sure that the flange is firmly secured to the floor.
You can do this by either using washers and nuts, or by using self-tapping screws.
Once you have the bolts firmly secured in place, you need to make sure that the flange gasket is in place. This will help create a waterproof seal between the floor and the flange, ensuring that any water leakage is trapped and diverted away.
Finally, if desired, you can use caulk to fill any small gaps or crevices between the flange and the floor. This will give the installation an extra layer of protection against water leakage.
Does toilet flange have to be glued in the pipe?
No, a toilet flange doesn’t have to be glued in the pipe, but using some sealant can make the installation process easier and more secure in many cases.
The toilet flange acts as a support on the bottom of the toilet and should be placed in the proper orientation so it’s flush on the floor. It attaches to the drain pipe in the floor. The two most common methods for installing a toilet flange are with screws or adhesive.
Screws are more secure and are used when the installation does not permit adhesives.
If it is possible to use adhesive with the installation, there are a few glues to choose from, including silicone, acrylic latex caulk, PVC cement or epoxy. To use any of these adhesives, apply the heat-activated glue to the toilet flange.
Make sure you apply it evenly before pressing the flange and pipe together.
Regardless of what adhesive you choose to use, it is important to take extra care to ensure the flange is properly positioned and aligned. Once the flange and pipe are glued, allow the adhesive to sit and cure properly and then your toilet should be properly secured.
How much does it cost to fix a toilet flange?
The cost of repairing a toilet flange can vary depending on the severity of the issue and the parts and supplies needed to complete the repair. Depending on the extent of the damage, a plumber may need to replace or adjust the flange and associated plumbing fixtures.
In general, the cost of replacing a toilet flange can range from around $75 to $200, not including any additional plumbing or labor costs. Additionally, if the flange is a part of a more complex plumbing issue that requires additional parts, such as a new gasket, wax ring, or toilet bolts, these additional parts and labor may increase the cost of the repair.
Can I replace a toilet flange myself?
Yes, you can replace a toilet flange yourself. The process is relatively straightforward, but you should ensure that you have the right tools and materials before getting started. To complete the job, you’ll need a screwdriver, a utility knife, a hacksaw, a drill, a hammer and a variety of plumbing supplies such as new wax rings, bolts, and a toilet flange.
There are five steps to replacing the flange, beginning by shutting off the water supply and draining the toilet tank. Next, you’ll need to remove the toilet from the floor and disconnect the water lines, caps and seals.
Once the water lines are disconnected, then you can carefully remove the old flange. Clean the mounting surface, making sure to remove any debris, then check to make sure that the bottom outlet of the waste pipe is in good condition.
Next, attach the new flange to the waste pipe using bolts and plumber’s putty, then install the wax ring onto the new flange. Finally, reset the toilet and reconnect the water lines and caps. If you’re new to plumbing or not quite sure of the steps, you might want to consider hiring a professional plumber to assist with the job.
Will toilet leak if flange is broken?
Yes, a broken flange can cause a toilet to leak. A toilet flange is a ring-shaped pipe fitting that connects the toilet to the drain pipe in the floor. It essentially acts as a seal between the toilet and the waste line.
If a flange is broken, the seal is broken and water will be able to escape and leak out. If the leak is minor, you may be able to temporarily fix it with plumbers putty. If it is more serious, the flange will need to be replaced in order to prevent any further leaks.
Allowing a toilet to leak for an extended period of time can cause permanent damage to the floor and walls of your home.
Do all toilets fit the same flange?
No, not all toilets fit the same flange. So it is important that you take accurate measurements to ensure your toilet fits. Flanges come in many different sizes, shapes, and materials. Common materials for a toilet flange include PVC, metal, and ABS plastic.
PVC and ABS plastic flanges are two of the most common materials used, with ABS plastic becoming more popular in recent years due to its durability and strength. The size of the flange needs to correspond with the type of toilet you are installing, and you will want to make sure the flange is the correct size and style for the model of toilet you are using.
It is also important to check the size and shape of the holes in the floor, as they will influence the type of flange that is required.
