Fixing A Broken Toilet Tank Lid: Diy Guide

A cracked toilet tank lid can be a challenging problem to fix, and while there is no permanent solution other than replacing the lid, a temporary fix can be achieved with some muscle and adhesive. The first step is to prepare the toilet tank lid by laying it on a flat surface with the bottom side facing upwards and drying it with a towel. The next step is to apply porcelain adhesive to the cracks, pressing the pieces together until the adhesive sets. This process should be done carefully to avoid further cracks or breakage. Once the adhesive has dried, the lid can be placed back on the toilet tank, being careful not to bump the edges. While this repair will only last a short time, it can be a useful temporary solution.

How to fix a broken toilet tank top

Prepare the toilet tank lid

Before you begin the repair, you'll need to prepare your work area. Choose an area that will not be disturbed and lay out some dry towels on a flat surface, such as the floor or a counter. Make sure the towels are large enough for the toilet tank lid to rest on without overhanging the edges. Place the lid on the towels with the bottom side facing up. If there are any broken pieces, arrange them to form the original shape and style of the lid. As you work, use a towel to dry off the pieces to ensure that the adhesive will bond correctly with the porcelain.

If your toilet tank lid is cracked, it's important to know that there is no way to completely eradicate the cracks. The only permanent solution is to replace the tank lid. However, with some muscle and the right adhesives, you can repair the lid as a temporary solution. This task is relatively easy and should not take more than an hour to complete with the proper supplies on hand.

Apply porcelain adhesive

Once you have prepared the toilet tank lid, it's time to apply the porcelain adhesive. This step requires careful attention to prevent further cracks or breakage. Here is a detailed guide on how to apply porcelain adhesive to fix a broken toilet tank lid:

Applying Porcelain Adhesive:

• Ensure that the toilet tank lid pieces are completely dry and arranged correctly, forming the original shape and style.
• Start applying the porcelain adhesive onto the inside of the cracks. Work on one section at a time to ensure a controlled and precise application.
• Press the pieces together firmly and hold them in place until the adhesive sets. This step should be done with extreme caution to avoid any additional cracks or breakage.
• Repeat the process for each section, bonding one area at a time until all the cracks have been addressed.
• Allow the adhesive to set undisturbed for an extended period, preferably overnight. Do not attempt to move or use the toilet tank lid until the adhesive has fully cured to prevent it from falling apart.

It is important to note that repairing a cracked porcelain toilet tank lid is only a temporary solution. With normal usage, the lid may develop cracks and require replacement eventually. However, by carefully applying porcelain adhesive and being gentle with the lid, you can extend its usability for a short period.

Replace the tank lid

Once you have sourced a new tank lid for your toilet, you can install it by following these steps:

• Carefully remove the old tank lid: If it is broken, be cautious not to cut yourself on any sharp edges or pieces.
• Clean the toilet tank: Ensure that the surface where the new lid will be placed is dry and free of any debris or residue.
• Prepare the new tank lid: Check that you have the correct size and colour for your toilet.
• Place the new tank lid: Gently set the new lid onto the toilet tank, ensuring it is secure and properly aligned.
• Check the fit: Once the new lid is in place, check that it fits correctly and does not wobble or move around.
• Test the toilet: Flush the toilet to ensure that the new lid is functioning properly and that there are no leaks.

Remember to dispose of the old tank lid properly and consider recycling it if possible.

Check for hairline cracks

Hairline cracks in a toilet tank can be difficult to spot, but they can lead to serious problems if left unattended. The first step is locating the hairline crack and assessing whether it can be fixed. These cracks often appear due to impact, age, or accidents. Even a small, innocuous crack can cause issues over time if not repaired.

Toilet tanks can have cracks above or below the water level, and on the inside or outside. A crack above the water level is usually not a problem unless it grows. If you spot a crack in the tank, keep an eye on it and consider taking a picture for later comparison. Mark both sides of the crack to make sure it's not growing.

A crack that is below the water level is more serious and will need to be fixed. If you suspect a leak from the toilet tank, check the seals between the tank and the bowl, and then carefully inspect the tank for a crack in the porcelain, both on the outside and the inside.

If you have a hairline crack in the tank, you can try to repair it by sealing the crack with waterproof epoxy or plumber's putty. Here's a step-by-step guide:

• Drain the toilet tank by turning off the water supply and flushing the toilet.
• Remove any remaining water with a sponge or bucket.
• Dry the tank with a cloth or towel, ensuring that the outside is also wiped down to prevent condensation.
• Mix the epoxy according to the manufacturer's instructions.
• Apply the epoxy to the crack, both from the inside and outside of the tank, using a putty knife or spreader.
• Smooth and flatten the epoxy for a better appearance.
• Let the epoxy cure overnight or as recommended by the manufacturer.
• Refill the toilet tank and check for leaks.

Remember that repairing hairline cracks with epoxy may not always work, and in some cases, replacement of the toilet tank may be necessary.

Use waterproof epoxy

If you have a hairline crack in your toilet tank, you may be able to seal the crack with waterproof epoxy. Firstly, turn off the water supply to the toilet at the shutoff valve below the toilet tank. Turn the valve clockwise until it stops. Flush the toilet to drain the water from the tank and bowl. Remove any standing water in the tank or bowl with a sponge and wring it out into a bucket. Next, wipe the porcelain dry.

Now, clean and sand the repair area. Sand the area with sandpaper to roughen the surface, but only sand the area where you will apply the epoxy. Rinse the area well and let it dry.

The epoxy comes in two parts: a catalyst and a resin. Mix these together as directed by the manufacturer. Immediately apply the mixed epoxy to the crack with a putty knife or spreader. Smooth and flatten the epoxy as much as possible for the best appearance. You must apply the epoxy within 30 minutes.

Let the epoxy cure overnight, or as recommended by the manufacturer. Once cured, open the shutoff valve to the toilet by turning its handle all the way counterclockwise. Let the toilet tank refill, then flush the toilet and check for leaks.
