Answer:
A toilet leaking between the tank and the bowl is usually due to a faulty tank-to-bowl connection.
These are typically the most common causes and recommended solutions to remedy the issue.
1. Worn-Out Rubber Gasket:
The most likely cause is a worn-out rubber gasket. This gasket acts as a seal between the tank and bowl. Over time, it can deteriorate, crack, or become dislodged, causing leaks.
Solution: Replacing the tank-to-bowl kit, which includes a new gasket, is a simple and effective solution. To ensure the correct fit, please identify your toilet model before purchasing a replacement kit.
2. Loose Bolts:
The bolts securing the tank to the bowl can loosen or corrode over time causing leaks.
Solution: Gently try to rock the toilet tank. If you notice movement, the bolts need tightening. Be careful not to overtighten, as this could damage the porcelain.
3. Cracked Toilet Bowl or Tank:
While less common, a crack in the toilet bowl or tank can also lead to leaks.
Solution: Cracks in the porcelain usually require replacing the damaged component, or in some cases, the entire toilet.
If you're unsure about the cause of the leak or how to fix it, we recommend contacting a licensed plumber.
