Removing the Old Toilet Bowl

When it comes to upgrading your toilet bowl in your bathroom, one of the most essential steps is choosing the right Rubine toilet bowl whether it is a one or two-piece toilet bowl. Before you can install your new Rubine toilet bowl, you need to remove the old one. 

Reminder before you start, know and follow the toilet bowl installation guide provided by the manufacturer. Begin shutting off the water supply to the toilet. Locate the shut-off valve, usually located on the wall behind the toilet, and turn it clockwise until it stops. Next, flush the toilet to drain the water from the tank and bowl. Use a sponge or towel to remove any remaining water.

Once the water is drained, it’s time to disconnect the water supply line. Use an adjustable wrench to loosen the nut connecting the supply line to the bottom of the toilet tank. Once the nut is loosened, carefully remove the supply line. Ensure that there is no damage in the supply line because this is one of the factors affecting the price of your toilet bowl replacement

To remove the old toilet bowl from the floor, locate the bolts securing it in place. These bolts are usually covered by plastic caps at the base of the toilet.

With the nuts removed, you can now lift the old toilet bowl and carefully set it aside. Once again, be careful on doing toilet bowl replacement by yourself. Always be aware of what you are doing especially when replacing your old toilet bowl. 

Additionally, take note of the things before a toilet bowl replacement like the measurement of its location, toilet bowl availabilities, and which is the best-suited toilet bowl for you.


Installing the Wax Ring and Flange


Now that you have removed the old toilet bowl, it’s time to prepare for the installation of your new Rubine toilet bowl. Start by inspecting the flange, which is the pipe fitting on the floor where the toilet bowl will be installed. Ensure that the flange is clean and free from any debris to prevent your toilet bowl from leaking. If necessary, use a scraper or brush to clean the flange.

Next, it’s time to install the wax ring. The wax ring creates a watertight seal between the toilet bowl and the flange. Place the wax ring on top of the flange, making sure it is centered and fitted to the trap of your toilet bowl whether you are using an S-trap or P-trap toilet trap type. Gently press down on the wax ring to ensure it adheres to the flange. Take care not to move or disturb the wax ring once it is in place.

Now, it’s time to position the Rubine toilet bowl in its right place. Whether your toilet bowl is a wall or floor-mounted toilet, make sure to attach it perfectly to the top of the wax ring position to avoid leakage and wastewater. Carefully lift the toilet bowl and align the holes at the base of the bowl with the bolts on the flange. Lower the toilet bowl onto the wax ring, ensuring a proper fit. Apply gentle pressure to make sure the toilet bowl is seated evenly on the wax ring. Once the toilet bowl is in position, it’s time to secure it. 


Positioning and Securing the Rubine Toilet Bowl


To prevent the reasons behind a leaking toilet bowl, you must secure the Rubine toilet bowl in place, start by placing the washers and nuts on the bolts protruding from the flange. Tighten the nuts with an adjustable wrench, but be careful not to overtighten, as this may crack the toilet bowl. Alternate between tightening each nut to ensure even pressure.

Once the toilet bowl is securely fastened to the flange, it’s time to check its stability and make sure that it will not occur any type of toilet bowl leaks over the course of time. Gently rock the toilet bowl back and forth to ensure it does not move or wobble. If you notice any movement that can cause leakage, tighten the nuts further until the toilet bowl is stable

With the Rubine toilet bowl properly secured, it’s time to move on to the next step of the installation process.


Connecting the Water Supply

Water supply is essential when it comes to functionality and flushing system. Be careful connecting them to make sure that to avoid common toilet flush problems such as slow fill, weak flush, and tank leaking. Now that your Rubine toilet bowl is securely in place, it’s time to connect the water supply. Begin by placing a new rubber gasket onto the fill valve located at the bottom of the toilet tank. This gasket ensures a watertight seal between the tank and the supply line.

Next, connect the water supply line to the fill valve. Tighten the nut with an adjustable wrench, ensuring it is snug but not overly tight. Once the supply line is connected, turn on the water supply by turning the shut-off valve counterclockwise. Be sure to check for any signs of water leakage around the fill valve and supply line. 

To ensure everything is functioning properly, flush it, observe the water flow, and inspect any toilet bowl leaks. If the water fills the tank and the bowl has any leakage issues, immediately follow the steps to take when your toilet bowl is leaking. After that, connect the water supply to your Rubine toilet bowl.


Testing and Finishing Touches


Now that your Rubine toilet bowl is fully installed and connected, it’s time to test its functionality to avoid common toilet bowl problems in the future.
