Did You Know?
1. The first flush toilet was invented in 1596 by Sir John Harington, a godson of Queen Elizabeth I. However, it was unreliable and gained little popularity until the 19th century.
2. Toilets operate on a principle known as the siphon effect. When you flush, the water in the toilet bowl creates a pressure imbalance that initiates a siphoning action, effectively pulling the waste down the drain.
3. The average American flushes the toilet about five times per day, which accounts for roughly 20% of the nation’s total daily water usage. Implementing low-flow toilets can significantly reduce water consumption and save around two gallons per flush.
4. A leaking toilet base is often caused by a faulty wax ring, a circular gasket that seals the connection between the toilet and the floor drain. This wax ring can become damaged over time, leading to leaks around the base of the toilet.
5. Some ancient civilizations, such as those in ancient Rome, had communal toilets where individuals sat next to each other with no partitions for privacy. These toilets, known as “latrines,” were used as social gathering places, where people would engage in discussions, read, or even gamble.
1. Turning Off The Water Supply
When facing a leaking toilet base, the first step is to turn off the water supply. Locate the shut-off valve usually located near the base of the toilet or on the wall behind it. Turn the valve clockwise until the water stops flowing into the toilet tank. This will prevent any further water leakage during the repair process.
2. Disconnecting The Supply Line
After turning off the water supply, remove the tank lid and flush the toilet to drain any remaining water in the tank and bowl.
Next, disconnect the supply line from the tank by twisting the nut counterclockwise. Use a pair of pliers or a crescent wrench, if necessary, to loosen the connection.
To avoid any water spills, place a bucket or towel under the disconnected supply line to catch any excess water that may still be in the line.
3. Removing The Toilet From The Base
To remove the toilet from the base, loosen the T-Bolts that secure it. Start by removing the plastic caps covering the bolts at the base of the toilet. Once the caps are removed, using a crescent wrench, loosen the bolts by turning them counterclockwise.
With the bolts loosened, lift the toilet straight up off the bolts. Be careful as the toilet is heavy and can be awkward to handle. Place the toilet gently on a thick cardboard or old towels to protect the floor and prevent any damage to the toilet.
4. Replacing The Wax Ring Seal
Now that the toilet is removed, it’s time to replace the wax ring seal. The wax ring is a crucial component that creates a watertight seal between the toilet flange and the base of the toilet. Start by scraping off the old wax ring from both the flange and the toilet base. Use a putty knife or scraper to remove any residue left behind.
Once the old wax ring is completely removed, replace the toilet bolts with either a 1/4″ or 5/16″ bolt and slide plastic washers over them. Next, place the new wax ring over the bolts, ensuring it is centered over the flange opening. Press the wax ring gently to create a proper seal between the flange and the toilet base.
5. Securing The Toilet Back On The Base
Instructions for Installing a Toilet:
- Carefully lift the toilet and align it with the bolts protruding from the floor.
- Lower the toilet onto the bolts, making sure that the wax ring stays properly in place.
- Apply pressure on the toilet bowl rim or seat to compress the new wax seal and ensure a tight fit.
- Tighten the bolts using a crescent wrench, being careful not to overtighten and crack the base.
- If the toilet wobbles after tightening, use rubber shims to stabilize it.
-
Finally, trim the excess length of the bolts using a hack saw or bolt cutters.
-
Lift the toilet and align it with the floor bolts.
- Lower the toilet onto the bolts, ensuring the wax ring is in place.
- Apply pressure to compress the new wax seal.
- Tighten the bolts without overtightening.
- Use rubber shims to stabilize a wobbly toilet.
- Trim the excess length of the bolts.
Note: It is important to carefully follow these steps to ensure a proper installation and prevent any damage to the toilet or the floor.
6. Finishing Touches And Safety Precautions
With the toilet secured back on the base, it’s time to reconnect the water supply line to the toilet tank. Twist the nut clockwise to secure the supply line back in place. Once the connection is tight, turn the water supply valve counterclockwise to allow water to fill the tank.
- Fill the tank completely and flush the toilet a few times to check for any leaks around the base.
- If there are no leaks, you can proceed with the finishing touches. Apply a bead of caulk around the base of the toilet to seal it to the floor. This will provide added protection against any potential water seepage.
Before wrapping up the repair process, it’s important to take necessary safety precautions. Always use gloves when working with toilets to protect yourself from any potential bacteria or germs. Additionally, clean the work area thoroughly with a disinfecting solution to maintain proper hygiene.
fixing a leaking toilet base can be a relatively easy DIY repair. Most repairs can be completed in just a half-hour and require inexpensive materials. By following the step-by-step guide provided above, you can successfully fix a leaking toilet base and prevent further damage to your bathroom.

Frequently Asked Questions
How do I stop my toilet base from leaking?
If you are experiencing a leaking toilet base, addressing the issue might be as simple as tightening the bolts that secure the toilet to the floor. To accomplish this, begin by removing the plastic caps covering the bolts using a putty knife or screwdriver. With a wrench, gently tighten each bolt, applying only mild pressure. This straightforward solution should help resolve the leakage problem and restore the proper functioning of your toilet.
What causes a toilet to leak from the bottom of the base?
A toilet leaking from the bottom of the base can occur due to several reasons. One possible cause could be a damaged wax gasket or loose mounting bolts. When the toilet is flushed, water could seep through these gaps and leak onto the floor. Another possibility is a faulty seal between the toilet tank and its base, which can result in a continuous leak. Additionally, a loose water supply line connection or a problematic water shutoff valve could also lead to a persistent leak from the bottom of the toilet. Identifying and addressing these issues promptly is important to prevent further damage and water wastage.
How do you seal the gap under the toilet?
To seal the gap under the toilet, you can use a sealant specifically designed for bathroom fixtures. Apply a thin layer of the sealant around the base of the toilet, covering the gap along the floor and concealing any shims if needed. It is important to ensure the caulk is even and smooth by using your finger to smooth it out, regularly cleaning your finger with a paper towel or rag for best results. This will effectively seal the gap and provide a clean and tidy finish to your toilet installation.
1. What are the common causes of a leaking toilet base and how can they be fixed?
There are several common causes of a leaking toilet base. The first is a faulty wax ring, which is a seal between the toilet and the floor. If this ring becomes damaged or worn out, water can leak from the base. To fix this issue, the toilet will need to be removed, the old wax ring replaced with a new one, and the toilet reinstalled.
Another cause of a leaking toilet base is a cracked toilet bowl. Over time, the porcelain bowl can develop cracks, leading to water leakage. In this case, the only solution is to replace the entire toilet bowl. It is important to identify the cause accurately before attempting any repairs to ensure the problem is resolved effectively.
