Why Install a New Toilet?

Installing a new toilet can bring numerous benefits to your home. Modern toilets are designed to be more water-efficient, which can save you money on your water bills. Additionally, new models often come with enhanced features such as better flushing mechanisms and more comfortable designs.

When to Replace Your Old Toilet

Knowing when to replace your old toilet is crucial. Common signs include frequent clogging, constant leaks, cracks in the porcelain, and outdated design. If your toilet is showing any of these symptoms, it might be time for an upgrade.

Preparing for the Installation

Before you start the installation process, make sure you have all the necessary tools and materials. These include the new toilet, a wax ring, toilet bolts, a putty knife, an old towel, a wrench, and a utility knife. Having everything on hand will make the process smoother and more efficient.

Removing the Old Toilet

Here’s how to remove your old toilet. Remember, if there are any concerns it’s best to reach out to a professional like MD Sewer and Plumbing.

Shutting Off the Water Supply

The first step in removing the old toilet is to shut off the water supply. Locate the water supply valve, typically found behind the toilet, and turn it clockwise until it is fully closed. Flush the toilet to drain the remaining water from the tank and bowl.

Disconnecting the Water Supply Line

Once the water is turned off, disconnect the water supply line from the toilet tank. Use a wrench to loosen the nut that connects the supply line to the tank. Be prepared for some water to spill out, so have an old towel handy to soak it up.

Removing the Old Toilet

To remove the old toilet, unscrew the bolts that secure it to the floor. These are usually located at the base of the toilet. Once the bolts are removed, gently rock the toilet back and forth to break the seal, then lift it straight up and out. Place it in a safe location, such as the garage, until you can dispose of it properly.

Preparing the Floor for the New Toilet

With the old toilet removed, you’ll need to clean the area where the new toilet will be installed. Use a putty knife to scrape away any old wax from the flange and floor. Ensure the area is dry and free of debris to prevent leaks.

Inspecting the Flange

Check the condition of the toilet flange, which is the fitting that connects the toilet to the drain pipe. If the flange is damaged or corroded, it will need to be repaired or replaced before proceeding with the installation.

Installing New Bolts

Place new toilet bolts into the flange, ensuring they are aligned with the bolt holes in the base of the new toilet. These bolts and closet bolts will secure the toilet to the floor, so make sure they are positioned correctly and securely.

Installing the Wax Ring

A wax ring creates a watertight seal between the toilet and the drain pipe. Place the new wax ring onto the flange, with the tapered end facing down. Press it firmly into place to ensure a good seal.

Positioning the Toilet Bowl

Carefully lift the new toilet bowl and position it over the flange, aligning the bolt holes with the bolts. Gently lower the bowl onto the wax ring, making sure it is level and centered.

Securing the Bowl

Once the bowl is in place, press down gently to compress the wax ring and create a seal. Hand-tighten the nuts onto the bolts, then use a wrench to tighten them further. Be careful not to overtighten, as this can crack the porcelain.

Attaching the Toilet Tank

With the bowl securely in place, it’s time to attach the toilet tank. Position the tank on the back of the bowl, aligning the bolt holes. Insert the tank bolts through the holes and tighten the nuts from underneath.

Securing the Tank

Tighten the nuts evenly to ensure the tank is level and secure. Be cautious not to overtighten, as this can also crack the porcelain. Once the tank is secure, attach the water supply line to the tank and tighten the nut.

Checking for Leaks

Turn the water supply valve back on and allow the tank to fill. Check for any leaks around the base of the tank and the connection to the water supply line. If you notice any leaks, tighten the connections slightly until they stop.

Choosing and Installing the Toilet Seat

Select a toilet seat that matches the design and color of your new toilet. Most toilets come with a basic seat, but you may want to upgrade to a more comfortable or stylish option.

Attaching the Seat

Position the seat on the toilet bowl, aligning the bolt holes. Insert the bolts through the holes and tighten the nuts from underneath and make sure its sealed using a toilet wax ring.

Make sure the toilet seats are leveled and secure before use.

Final Adjustments

Give the toilet a final check to ensure everything is secure and functioning correctly. Tighten any loose connections and make sure the toilet is level. Once you are satisfied, your new toilet installation is complete!

Maintaining Your New Toilet

To keep your new toilet in top condition, clean it regularly with appropriate cleaning products. Avoid using harsh chemicals that can damage the porcelain and always follow the manufacturer’s cleaning instructions.

Checking for Leaks

Periodically check for leaks around the base of the toilet and the connections to the water supply line. Early detection of leaks can prevent water damage and save you money on repairs.

Professional Inspections

Consider having a professional plumber inspect your toilet and plumbing system annually. A master plumber can identify potential issues early and ensure your toilet remains in optimal condition.

Common Installation Mistakes to Avoid

Here are a few mistakes commonly made by DIY enthusiasts when it comes to toilet installation.

Skipping the Wax Ring

One common mistake is failing to install a new wax ring. The wax ring is essential for creating a watertight seal and preventing leaks. Always use a new wax ring when installing a toilet.

Overtightening Bolts

Overtightening the bolts that secure the toilet to the floor or tank can crack the porcelain. Tighten the bolts just enough to secure the toilet without causing damage.

Ignoring Flange Issues

If the toilet flange is damaged or corroded, it must be repaired or replaced before installing the new toilet. Ignoring flange issues can lead to leaks and an unstable toilet.

Troubleshooting Installation Issues

Here are a few common installation issues people run into during and after the install.

Toilet Wobbles

If your toilet wobbles after installation, it may not be level. Use shims to level the toilet, then tighten the bolts evenly to secure it in place.

Persistent Leaks

Persistent leaks may indicate an issue with the wax ring or flange. Remove the toilet and inspect the wax ring and flange for damage. Replace any damaged components and reinstall the toilet.

Weak Flush

A weak flush can result from a partially closed water supply valve or a clogged drain. Check the water supply valve to ensure it is fully open and inspect the drain for blockages.
