Cracked toilet tanks can be a real hassle for homeowners. Not only are they unsightly, but they can also lead to leaks and water damage. This article will provide a step-by-step guide on how to replace a cracked toilet tank.

We will cover everything from assessing the damage to gathering the necessary tools and materials, replacing the tank, and maintaining it.

Assessing the Damage

Types of Cracks that Can Occur in Toilet Tanks

When assessing the damage to a toilet tank, it’s essential to identify the type of crack that has occurred. Several types of cracks can occur in toilet tanks, including hairline cracks, complete breaks, and cracks around the mounting bolts.

Hairline cracks are small and not always visible to the naked eye. Full breaks, however, are significant and often result in leaks. Cracks around the mounting bolts can occur if the bolts have been over-tightened, causing the porcelain to crack.

How to Identify if a Toilet Tank is Cracked

To identify if a toilet tank is cracked, you can run your hand over the surface of the tank, or you can use a flashlight to examine it more closely. If you cannot see the crack with the naked eye, you can also check for leaks or water damage around the toilet’s base.

Determining the Severity of the Crack

Once you’ve identified that a crack is present, it’s essential to determine the severity of the crack. A small hairline crack may not require immediate replacement, whereas a large full break will. It’s necessary to address any cracks as soon as possible to prevent further damage and potential leaks.

Safety Precautions

When working with plumbing, taking the necessary safety precautions is essential. Always shut off the water supply before assessing or replacing a toilet tank. It will prevent water from flowing into the tank while you’re working on it.

Also, make sure to wear gloves to protect your hands from any sharp edges or debris. And always be sure to proceed with caution when assessing the damage or replacing a toilet tank to avoid accidents.

Preparing for the Replacement

Gathering Necessary Tools and Materials:

Before replacing your cracked toilet tank, gathering all the necessary tools and materials is essential. You will need a new toilet tank, a new jamb nut, an adjustable wrench, and possibly a new supply line. It’s also a good idea to purchase a new wax ring and mounting bolts. Make sure to have all these materials ready before starting the replacement process.

Cost and Materials

It’s essential to have an estimate of the cost of the replacement and the materials. It will help you budget for the replacement and avoid any unexpected expenses. Check for any warranties or guarantees on the materials you purchase. You need to return or exchange them.

Shutting off the Water Supply

Before beginning the replacement process, shutting off the water supply is crucial. It will prevent water from flowing into the tank while you’re working on it. This step is vital for safety and to avoid any water damage.

Emptying the Tank

The next step is to empty the tank. It can be done by flushing the toilet several times until emptying the tank. It will make it easier to remove the old tank and install the new one.

Troubleshooting

Before starting the replacement process, it’s important to troubleshoot any potential issues that may arise. It could include checking for leaks or loose connections in the current tank or identifying potential problems with the new tank or materials. Troubleshooting beforehand can save time and resources in the long run.

Replacing the Tank

Step-by-Step Instructions:

  1. Test whether the jamb nut holding the tank’s supply line is loose.
  2. If it is, use an adjustable wrench to tighten the nut.
  3. Proceed carefully, as the nut and fitting are likely made of nylon and can strip when over-tightened.
  4. The porcelain tank is also susceptible to cracking from the pressure of over-tightened nuts.
  5. The nuts should be snug, only a quarter turn past hand tightening.

Removing the Old Tank

  1. Once the jamb nut is tightened, remove the mounting bolts that hold the tank to the bowl.
  2. Be sure to carefully remove the nuts and bolts, as they may be rusted or corroded.
  3. Once the nuts and bolts are removed, lift the old tank off the bowl.

Installing the New Tank:

  1. Before installing the new tank, place the new wax ring on the bowl’s rim.
  2. It will help to create a watertight seal between the tank and the bowl.
  3. Once the wax ring is in place, set the new tank and secure it with the mounting bolts.

Reconnecting the Water supply

  1. Once the new tank is securely in place, reconnect the water supply.
  2. This can be done by attaching the new supply line to the tank and securing it with the jamb nut.
  3. Be sure to tighten the nut just enough to create a watertight seal.

Testing for Leaks

  1. After reconnecting the water supply, turn it on and check for any leaks.
  2. If there are no leaks, proceed to the next step.
  3. If there are leaks, check the connections and tighten the nuts again.

Timeframe

Replacing a cracked toilet tank can take anywhere from a few hours to a full day, depending on the crack’s severity and the task’s complexity. It is essential to have all the necessary tools and materials on hand before beginning the replacement process, as this can help to streamline the process and minimize the time frame.

DIY vs. Professional

Many homeowners choose to tackle the task of replacing a cracked toilet tank on their own as a DIY project. However, for those who are not comfortable with plumbing or are unsure of their abilities, it may be best to hire a professional plumber to handle the task.

Hiring a professional plumber can ensure the job is done correctly and save time and money in the long run. Additionally, experienced plumbers are well-equipped with the right tools and knowledge to tackle any problem.
