If you're dealing with a leaky toilet, you may need to replace the rubber seal at the back of the toilet, known as the pan cone rubber. This is a relatively simple and inexpensive fix, but there are several steps to ensure you don't make a mess or damage your toilet system. First, turn off the water supply and drain the toilet tank. Then, locate the rubber gasket and remove the old one. Position the new cone gasket and guide the water supply line back into place, tightening the nut with a wrench. Turn the water supply back on and test for leaks. You may need to use a flathead screwdriver to remove the locking ring, but be careful not to crack the plastic. In some cases, you may need to cut the pipe for easier access, but always assess this before making any cuts.

What You'll Learn
Turn off the water supply
Before you begin to replace the rubber toilet pan connector cone, it is important to turn off the water supply to prevent leaks and potential flooding, which could damage your home.
First, locate the water supply valve on the wall behind your toilet. This valve controls the flow of water to your toilet. Once you have located it, turn the valve clockwise until it stops. This will shut off the water supply to your toilet and prevent any water from flowing into the tank.
It is important to note that different toilet designs may have slight variations in the location of the water supply valve. If you are unable to locate the valve behind the toilet, you may need to check the cold water pipe where it attaches to the cistern. This pipe is usually flexible, allowing for some movement. In some cases, you may need to shut off the water at the valve and unscrew the pipe before proceeding with repairs.
After turning off the water supply valve, remove the lid from the top of the toilet tank. Then, flush the toilet to drain the water inside. There will still be a small amount of water remaining at the bottom of the tank, which you can use a towel to mop up. Ensure you get as much water out of the tank as possible to create a dry working environment.
By turning off the water supply valve and emptying the tank, you can now safely work on replacing the rubber toilet pan connector cone without the risk of water leakage or damage to your property. Remember to keep old towels and a jug handy during the replacement process, just in case any residual water needs to be addressed.

Remove the old gasket
Before you begin, make sure you have turned off the water supply by turning the valve clockwise until it stops. You can locate the water supply valve on the wall behind your toilet. This is important to prevent creating a mess and causing flooding that can damage your home.
Now, to remove the old gasket, start by following the water supply line to the bottom of the toilet tank and locating the connecting nut where this line reaches the tank. The rubber gasket around the fill valve is the cone joint or cone gasket that you need to replace. Slide the old gasket out of place. If it is stuck, use pliers to grasp and pull it free. Be careful, as a very old and worn gasket may come apart when removed.
If your gasket is a flexible rubber pipe, it is likely called a pan connector. Sometimes, there is an extra rubber piece between the toilet and the pipe, usually in the case of an offset connector. This is also easy to replace. Often, a pan connector will have a flexible section, making it adjustable for height, length, or bends.
Whether you need to move the toilet to access the old gasket depends on how much access you have to the existing pan connector. If you need to move the toilet, be aware that it may be screwed into brackets attached to the floor, so you may need to lift it over the brackets.

Position the new cone gasket
Positioning the new cone gasket is a crucial step in replacing your toilet's rubber pan connector cone. Here is a detailed guide to help you through the process:
Prepare the Work Area: Before positioning the new cone gasket, ensure you have turned off the water supply by turning the valve clockwise until it stops. Also, have a small towel handy to mop up any remaining water from the tank. It is important to work in a dry environment to avoid slipping and to prevent water damage.
Remove the Old Gasket: If you haven't already done so, remove the old gasket. You can do this by sliding it out of place. If it is stuck, use a pair of pliers to grasp and pull it free. Be careful, as very old and worn gaskets may come apart when removed.
Insert the New Cone Gasket: With the old gasket removed, it's time to position the new cone gasket. Hold the new gasket with one hand and guide it into place around the fill-valve shank, which protrudes from the bottom of the tank. Ensure that the gasket is securely seated and centred on the shank.
Secure the Gasket: Once the new cone gasket is in position, use your other hand to guide the water supply line back into place. Hold the gasket firmly in place while doing this to avoid dislodging it. Then, reattach the nut to the shank. Tighten the nut with your hand first, and then use a wrench to give it one or two more full turns to ensure a tight seal. Be careful not to over-tighten the nut, as these parts are usually plastic and can be damaged by too much pressure.
Test the Connection: After securing the nut, slowly turn on the water supply valve by turning it counterclockwise. Allow the tank to refill with water. Once it is full, flush the toilet and let the tank refill again. Carefully inspect the new cone gasket and the surrounding area for any signs of leaks. If you notice any leaks, you may need to tighten the connection further or adjust the gasket's position.
Remember to work carefully and follow each step methodically to ensure a successful replacement of your toilet's rubber pan connector cone.

Reattach the nut to the shank
Reattaching the nut to the shank is a crucial step in replacing a toilet cone joint and preventing leaks. Here's a detailed guide on this process:
Locate the Shank: Begin by identifying the threaded shank of the fill valve, which protrudes from the bottom of the tank where the water supply line was previously attached. This is where the new cone gasket will be positioned. Ensure you have purchased a compatible model of the cone gasket from a hardware or plumbing supply store.
Position the Gasket: Place the new cone gasket securely around the fill valve shank. Hold it firmly in position with one hand.
Guide the Water Supply Line: With the gasket in place, carefully guide the water supply line back into its original position. Ensure that the gasket remains properly seated on the shank during this step.
Reattach the Nut: Now, reattach the nut to the shank by tightening it with your hand first. Once it feels hand-tight, use a wrench to give it one or two additional full turns. Be cautious not to over-tighten the nut, as this can damage the plastic components. Only tighten it enough to create a complete seal at the connection.
Check for Leaks: After tightening the nut, it's time to test the new connection. Turn on the water supply valve slowly by twisting it counterclockwise. Allow the tank to refill with water. Once it's full, flush the toilet and let the tank refill again. Carefully inspect the connection for any signs of leaks.
Replace the Lid: If you're confident that the connection is secure and there are no leaks, place the lid back onto the tank. You've now successfully replaced the rubber toilet pan connector cone and addressed any leakage issues.
Remember, when dealing with plumbing issues, it's always important to turn off the water supply first to avoid creating a mess or causing damage due to leaking water.

Test the system
Once you have installed your new toilet pan connector, you can test the system to ensure there are no leaks.
Firstly, connect the water and flush the toilet a few times. Check for any obvious drips or leaks. If there is no constant sound of running water, but there is a leak on the floor, the toilet pan connector is usually the component at fault.
For the next few days, keep an eye on the toilet to ensure it is fitted properly and there are no further leaks around the bowl. You can also try dumping a few buckets of water to test for leaks. If the connector feels a bit damp, this could be because you were moving the toilet back and forth to get it straight.
If you experience any leaks or issues with wastewater, it is recommended to call a qualified plumber. This will avoid wasting water, damaging your home, and causing hygiene issues.
