The toilet, a seemingly insignificant household item, plays an integral role in our lives. Its presence ensures hygiene and ease of living in the home. However, many homes are left in an awkward situation when this “hero” of the household malfunctions due to a broken tank. Can you imagine how embarrassing the scene would be at a party when the toilet suddenly leaks? To avoid this misfortune, it’s especially important to understand the cause of the crack and how to fix a cracked toilet tank.
Causes and iocations of cracks in the tank
The appearance of cracks can be caused by the following reasons:
- Prolonged use: Just like any other household item, prolonged use can lead to fatigue of the water tank material, which can result in small cracks.
- Impact of objects: Whether it’s an accident or a child’s prank, the impact of heavy objects is a common cause of cracks.
- Temperature changes: Sudden temperature changes, such as alternating hot and cold water, can cause the material to expand and contract, increasing the risk of cracks.
- Installation problems: If too much pressure is applied or the tank is twisted during installation, this can lead to cracks at a later stage.
- Material defects: Even brand-new toilets can crack due to manufacturing defects.
Location
The location of a crack can sometimes help us determine its cause:
- Bottom of Tank: Usually caused by prolonged water pressure or heavy impact.
- Around the tank: This may be due to installation problems or impact on an object.
- Water tank cover: mainly due to object impact or misuse.
- Connections or fixing points: Cracks at these locations are usually caused by installation problems or prolonged use.
What are the materials for toilet tanks?
The choice of material for the toilet cistern, not only affects the appearance and texture of the toilet but is also closely related to its durability and longevity. Here are a few common materials:
- Ceramic: Offers a classic look, smooth surface, and good durability. It is the material of choice for household toilets.
- Plastic: Lightweight and unbreakable. Mainly used for lightweight or portable toilets.
- Fiberglass: A composite of fiberglass and resin that combines the benefits of plastic and ceramic.
- Metal (e.g. stainless steel): More common in public or industrial environments, with excellent durability and antimicrobial properties.
Each material has its own characteristics, and in order to choose the toilet that best suits your needs, you need to take into account its use, budget, and personal preferences.
How to fix a cracked ceramic tank
Find a cracked toilet tank? Don’t stress. While this may seem like a big problem, you can actually fix it completely on your own with the right methods and tools. Here are the detailed steps to help you fix it easily!
1. Turn off the water
First, make sure you turn off the water supply to the tank. Most toilets have a water supply valve, usually located underneath or behind the tank. Slowly turn the valve until you feel the water stop flowing.
2. Drying the water tank
Make sure the inside of your water tank is completely dry before repairing the crack. You can use a sponge or towel to soak up the water inside the tank. Make sure the surrounding area is also clear and free of residual water droplets.
3. Prepare ceramic sealant or epoxy resin
There are a variety of sealers and epoxies on the market that are specifically designed for restoring ceramics. Visit your local hardware store or purchase them online. Make sure to prepare and mix according to product instructions for best results.
4. Applying the sealant
Clean the cracked area, making sure it is free of dust and oil.
Using a brush or plastic scraper, carefully apply the sealer, making sure the crack is completely covered.
Focus on avoiding over-application to avoid wasting material.
5. Smoothing sealant
Once the cracks have been fully coated, use a flat blade or spatula to gently smooth the surface. This ensures that your repair is not only functional but also looks as good as it did. If you have a moist paper towel or sponge, use it to gently smooth the surface for a more even finish.
6. Wait for it to dry
This is probably the most important step! Follow the product instructions and allow the sealer to dry completely. Typically, this can take 24 to 48 hours. Make sure you avoid using or touching the toilet during this time as this may affect the restoration.
