What You'll Learn

Cutting the pan connection
When installing a toilet pan collar, you may need to cut the pan connection if the old connection is damaged or incompatible with the new toilet. This job is best done by a professional plumber, but if you choose to do it yourself, here is a step-by-step guide:
First, turn off the water supply to the toilet and flush the toilet to empty the tank and bowl. Then, carefully disconnect the water supply line from the toilet. Next, you will need to remove the old toilet. This may involve breaking the toilet or cutting the locking ring with an oscillating multitool if it is cemented in place. Be careful not to damage the surrounding plumbing or the waste pipe. Once the old toilet is removed, you can begin cutting the pan connection.
Use a sharp knife or a hacksaw to cut through the pan connection, making sure to wear protective gloves and eye protection. Cut as close to the base of the toilet as possible to ensure a clean and tidy finish. After cutting, use a file or sandpaper to smooth out any rough edges. This will ensure that the new toilet pan collar fits properly and there are no leaks. It is important to handle the waste properly, so have a bin bag ready to dispose of any debris or old parts.
If you are installing a new toilet, follow the manufacturer's instructions for assembling and installing the toilet pan collar. Ensure that all connections are secure and properly aligned. Finally, turn on the water supply and check for any leaks. Test the toilet by flushing it several times to ensure that it is functioning properly.
Remember, plumbing can be complex, and it is always best to consult a professional if you are unsure about any part of the process.

Removing the old connection
Before installing a new toilet pan collar, you must first remove the old connection. This process can be tricky, and it is recommended that you seek professional help, especially when it involves toilet installations.
To begin, cut the pan connection off using the appropriate tools. This step may require some force, so be sure to take the necessary safety precautions and wear protective gear. Once the old connection is cut, carefully remove any remaining parts of the old collar, ensuring that the area is clear and free of debris. Use a suitable solvent or cleaning agent to remove any remaining adhesive or residue left by the old collar. It is important to ensure that the surface is clean and dry before proceeding.
If there are any pipes or fittings still attached to the old collar, these must also be carefully removed or detached. This process may require additional tools and expertise, so consider seeking assistance from a qualified plumber if you are unsure or uncomfortable proceeding on your own. It is important to take precise measurements of the old collar's diameter and the pipe size to ensure a proper replacement.
Finally, inspect the area for any damage or irregularities that may have occurred during the removal process. Ensure that the surrounding area is sturdy and intact, as this will provide a stable foundation for the new toilet pan collar installation. Any damage to the flooring or surrounding structures should be addressed before proceeding with the installation.

Measuring the internal collar hole
Start by removing the existing toilet pan collar. This will give you access to the internal collar hole and provide a clear space to work with. Be careful not to damage the surrounding area, and ensure that you have the necessary tools and safety equipment before proceeding.
Clean the area thoroughly to ensure that no debris or residue is left behind. This step is important as it ensures a clear and accurate surface for taking measurements. Use appropriate cleaning agents and tools to remove any dirt or stains.
Take precise measurements of the internal collar hole. Employ a measuring tape or a caliper to accurately determine the diameter and depth of the hole. Precision is crucial during this step as the measurements will dictate the size and type of replacement collar required.
Compare your measurements to standard toilet pan collar sizes. Toilet pan collars typically come in specific size ranges, so finding a close match to your measurements is essential. Consider the diameter and thickness of the collar to ensure a proper fit.
Consider any offsets or adjustments. If your measurements deviate from standard collar sizes, you may need to explore options such as offset pipes or adjustments. This could involve modifying pipe lengths or using adapters to ensure a secure connection.
By carefully measuring the internal collar hole, you can make informed decisions about replacement parts and adjustments, ensuring a successful toilet pan collar installation. Always adhere to local plumbing guidelines and seek professional advice if needed.

Using the correct pipe
It is important to use the correct pipe when installing a toilet pan collar. In one instance, a user tried to use PVC cement to attach an offset pipe to a pan collar but found that the cement would not stick to the plastic collar. It is recommended to seek professional help for toilet installations and similar plumbing jobs to ensure that the pipework is replaced properly.
The internal collar hole diameter is typically around 94mm, so a standard 110mm offset pipe will not fit. In this case, the user removed the rubber seal, but it is unclear if they found a solution or if they needed to replace the entire collar.
If you are installing a new toilet pan collar, make sure that you have the correct size pipe for your specific toilet model and type of connection. There are different types of pipes and fittings available, so it is important to choose the right one to avoid leaks and other issues.
You may need to use a wax ring, also known as a wax seal, to create a tight seal between the toilet horn (the drainpipe from the toilet) and the waste line (the pipe in the floor that carries waste away). The wax ring should be placed underneath the toilet horn, creating a watertight seal when the toilet is lowered onto the waste line.
In some cases, you may need to use a closet flange, which is a metal or plastic ring that fits over the waste line and provides a stable base for the toilet to rest on. Make sure you follow the manufacturer's instructions and local plumbing codes when installing the toilet pan collar to ensure a proper and safe installation.
