A properly functioning toilet is an essential part of any household and a crucial component of plumbing systems. Among the many elements that contribute to a toilet’s performance, the toilet bowl flange plays a pivotal role. The flange is the fitting that connects the toilet to the floor and the waste pipe. Over time, a toilet flange may become too low for the toilet to function correctly, leading to various issues such as leaks, a wobbly bowl, and unpleasant odors. In this article, we will explore the reasons for raising a toilet bowl flange and provide a step-by-step guide on how to do it effectively.
Understanding Toilet Bowl Flanges
Before diving into the methods of raising a toilet bowl flange, it’s essential to understand what it is and its role in toilet functionality. The toilet flange is a circular fitting that attaches to the drainpipe and the floor, providing a secure and stable base for the toilet. It also serves as a seal to prevent leaks while allowing waste to flow smoothly into the drainage system.
The flange is typically made from PVC, metal, or wax, and it must sit level with the finished floor for optimal installation. If the flange is too low, the toilet may not seal properly, leading to leaks or malfunctions. Furthermore, a low flange can cause the toilet to rock, which not only is uncomfortable but can also damage the wax seal.
Why Raise a Toilet Bowl Flange?
Various reasons may necessitate raising a toilet bowl flange, including:
- Floor Leveling: If you’ve installed new flooring, such as tile or laminate, the height of the finished floor may raise above the existing toilet flange, resulting in a low flange.
- Flange Damage: Damage can occur due to corrosion or physical impacts, necessitating a replacement or adjustment to ensure proper functionality.
- Improper Installation: Sometimes, the flange is simply installed too low during original construction or renovations.
- Changing Toilet Styles: Upgrading to a toilet model that operates better with a higher flange might require elevation to maintain optimal performance.
Tools and Materials Needed
To raise a toilet bowl flange, you will need a few essential tools and materials:
- Flange risers or extension kit (this can be found at any hardware store)
- Wax seal (preferably a new one)
- Caulking gun
- Screwdriver or drill
- Adjustment shims (if necessary)
- Spirit level
- Plumber’s putty (optional)
- Safety goggles and gloves
- Bucket or sponge (for water removal)
Step-by-Step Guide to Raise a Toilet Bowl Flange
Step 1: Prepare the Area
Before starting any plumbing work, it’s crucial to prepare the area and ensure safety. Begin by shutting off the water supply to the toilet. This is usually done by turning the valve located near the floor behind the toilet. Once the water supply is off, flush the toilet to empty the tank and bowl as much as possible.
Use a bucket or sponge to remove any remaining water from the toilet bowl. Remove any items around the toilet to create a clear workspace.
Step 2: Disconnect the Toilet
To effectively raise the flange, you will need to remove the toilet. Start by disconnecting the water supply line from the toilet tank. Use a wrench if it’s tightly secured. Next, unscrew the nuts holding the toilet to the flange, usually located under the bowl. Be careful as you lift the toilet off the flange – it’s often heavy, and you may want an extra set of hands to assist you.
Once detached, place the toilet on a towel or blanket to protect it and keep it stable while you work on the flange.
Step 3: Inspect the Existing Flange
With the toilet removed, take a good look at the existing flange. Assess for any damage or wear that could affect the toilet’s functionality. Check if the flange is currently level with the finished floor. If it’s below the surface, you’ll need to either replace it or use an extension to raise it.
Step 4: Select the Right Extension Kit
Depending on how much you need to raise the flange, you may choose a flange riser or an extension kit. Flange risers are easy to install and are typically made from PVC or ABS. If the existing flange is cracked or damaged, you may need to replace the flange entirely.
Step 5: Install the Extension Kit or Riser
If you’re using a flange riser, simply place it over the existing flange, ensuring it fits snugly. For an extension kit, follow the manufacturer’s instructions on how to install it. These kits often come with screws, and it is essential to secure them tightly to avoid any movement.
Once installed, use a spirit level to ensure that the top of the riser or extension is level with the new flooring. Adjust with shims if needed, making sure everything is even to provide a solid base for the toilet.
Step 6: Replace the Wax Seal
Before reattaching the toilet, replace the wax seal. This is critical to prevent leaks from occurring. Take the new wax seal and place it on top of the outlet of the flange or on the bottom of the toilet bowl itself.
Step 7: Reinstall the Toilet
Carefully lift the toilet back into position over the flange. Align the toilet bolts with the holes on the base of the toilet. Gently lower the toilet into position, applying even pressure to compress the wax seal beneath. Avoid rocking the toilet as you do this.
Once positioned correctly, fasten the nuts onto the bolts and tighten them until they are secure but avoid over-tightening, as this can crack the porcelain.
Step 8: Reconnect the Water Supply
After securing the toilet, reconnect the water supply line and turn the valve back on. Allow the tank to fill and check for any leaks around the base.
Step 9: Test the Flush
Once the tank is filled, test the toilet by flushing it a couple of times. Watch for any signs of leaks around the base or from the water supply line. If everything is functioning as it should, your job is complete.
Conclusion
Raising a toilet bowl flange is a necessary task that can significantly improve the functionality of your toilet. Whether you’re dealing with a new floor installation, flange damage, or simply the wish to upgrade your toilet, knowing how to raise your flange can save you time and money by preventing future issues.
With the right tools and a little bit of patience, you can effectively raise your toilet flange and ensure your toilet operates effectively and efficiently. If at any point you feel unsure about the process or run into complications, consider hiring a professional plumber to assist with the installation.
