How To Raise Your Toilet Flange By 1 Inch: A Simple Guide

A toilet flange is a crucial component that connects the toilet to the drainpipe. If the flange is too low, it can lead to leaks and other plumbing issues. In such cases, raising the toilet flange by 1 inch becomes necessary. This comprehensive guide will provide you with step-by-step instructions and valuable tips on how to successfully raise a toilet flange 1 inch.

Understanding the Need for Raising a Toilet Flange

Improper Height: If the toilet flange is too low, the toilet bowl may not sit level, causing rocking or wobbling. This can lead to leaks at the base of the toilet and potential damage to the floor.

Floor Replacement: When replacing flooring, the new floor may raise the level of the floor, making the existing toilet flange too low. Raising the flange ensures a proper connection and prevents leaks.

Plumbing Code Compliance: Building codes often specify the minimum height of the toilet flange above the finished floor. Raising the flange to the required height ensures compliance with code requirements.
