Why the Height of the Toilet Flange Matters

The proper height of the toilet flange is essential for the smooth operation of your bathroom. If it is not adjusted correctly, it can lead to water leakage, floor damage, and an unstable toilet bowl. To avoid these inconveniences, make sure to install the flange properly.

This small but significant detail will prevent leaks, provide a secure connection, and ensure a stable placement of the toilet bowl. It’s a crucial aspect to consider when it comes to your bathroom plumbing.

Physical Indications

Water leaking around the base of your toilet, visible cracks or damage on the bathroom floor, or difficulty aligning the toilet bowl may all be indications of a high toilet flange. Though seemingly insignificant, these issues can escalate into major problems if not dealt with promptly. Leakage around the base of the toilet suggests that the flange is not properly sealed to the floor.

This can result in costly water damage to the bathroom floor and create an environment conducive to mold and mildew growth, which can be harmful to your health. Cracks or damage visible on the bathroom floor are another telltale sign of a high toilet flange. The excessive pressure exerted on the floor by the elevated flange can lead to long-term damage and structural issues within your bathroom.

Neglecting this can have serious consequences. Struggling to align the toilet bowl is also a common indicator of a high toilet flange. When the flange is elevated, achieving a level and stable toilet bowl becomes challenging.

This can result in an unstable and potentially hazardous toilet bowl that may wobble or rock. It is crucial to address these signs promptly. Ignoring a high toilet flange can result in further complications down the line.

Seeking professional assistance to realign and stabilize the toilet bowl is the best course of action, preventing further damage and inconvenience.
