will the toilet leak if its not leveled

9November 2023

When installing a toilet, one critical aspect often overlooked is ensuring that the toilet is level. A toilet that isn’t level can lead to several problems, some of which may not be immediately apparent.

Why a Level Toilet is Essential

A level toilet is crucial for several reasons. For one, it ensures that the toilet sits flush against the wax seal, which prevents leaks at the base. If the toilet is not level, there can be gaps that allow water to seep out every time the toilet is flushed. This constant leaking can damage your bathroom floor over time, leading to costly repairs.

Signs of a Non-Level Toilet

  • Visible gaps: One side of the toilet base is higher than the other.
  • Movement: The toilet rocks or moves when you sit on it.
  • Leaks: Water appears on the floor around the base after flushing.

Consequences of a Non-Level Toilet

  • Leaks: The most apparent issue with a non-level toilet is leaking. The weight distribution can put pressure on one side, breaking the wax seal.
  • Uneven Wear: An uneven toilet can lead to irregular wear on its parts, particularly the flapper and fill valve, leading to further leaks or inefficiencies.
  • Cosmetic Damage: Over time, a leaking toilet can cause staining, rot, or mold growth on the flooring, which may become a health hazard.

Leveling a Toilet

If you find that your toilet is not level, it’s often a simple fix:

  1. Tighten or loosen the bolts: Sometimes, simply tightening or loosening the bolts that hold the toilet to the floor can fix a minor leveling issue.
  2. Use shims: Toilet shims can be used to level out the toilet. Once inserted, you can caulk around the base to seal and hide the shims.
  3. Replace the wax ring: If there has been a leak, replace the wax ring before reseating the toilet.

Professional Help

If you’re uncomfortable leveling the toilet yourself or if there’s significant damage due to leaking, it’s best to call a professional plumber. They can ensure that the toilet is properly installed, leveled, and sealed, preventing future leaks and damage.

Preventive Measures

  • Always check the level during installation.
  • Perform routine inspections to catch leaks early.
  • Address any bathroom floor unevenness before installing the toilet.

In summary, a toilet must be level to function correctly. If not, it can result in leaks that may lead to significant damage over time. Always ensure proper installation, and do not hesitate to correct any leveling issues promptly.
