A toilet flange is a crucial component in any bathroom. It connects the toilet bowl to the drainpipe and helps form a secure seal to prevent any leakages. There are mainly two types of toilet flanges: the pvc and the cast iron flange.

The pvc is ideal for new installations, and the cast iron flange is preferred in remodeling projects. Pvc flanges are lightweight, easy to install, and corrosion-resistant. On the other hand, cast iron flanges are more durable, making them perfect for remodeling projects.

Therefore, before installing a toilet, it is essential to determine the type of flange that suits your bathroom. Proper installation of a toilet flange is critical to ensure a snug fit, which eliminates any possibility of leakages and related issues.

Do You Really Need To Glue Your Toilet Flange?

The use of glue when installing a toilet flange depends on various factors. If you’re dealing with an uneven floor or removing a broken flange, gluing may be necessary to prevent leaks. On the other hand, if the flange fits perfectly over the drainpipe and the floor is level, gluing it isn’t necessary.

Plus, using glue sometimes makes future repairs more difficult. When installing a new flange, it’s best to follow the manufacturer’s instructions and use the appropriate solvent/cement. However, if the flange is in good condition and sits securely, you don’t have to glue it as it can still function properly.

Ultimately, the decision to glue your toilet flange depends on whether it needs the extra stability or not.
