How to Choose the Best Toilet Mounting Parts

Understanding Toilet Mounting Parts

Proper toilet mounting ensures stability and prevents leaks. Key components include the wax ring, closet bolts, and flange. The wax ring creates a watertight seal between the toilet and the drainpipe, while closet bolts secure the toilet bowl to the floor flange. The flange, typically made of PVC or cast iron, connects the toilet to the waste line and anchors it to the subfloor.

Types of Wax Rings

Standard wax rings are the most common, offering a reliable seal. For uneven floors or slightly off-center flanges, consider wax rings with a built-in horn, which helps guide waste into the drainpipe. Extra-thick wax rings are available for situations requiring a taller seal or to compensate for minor imperfections in the floor.

Choosing Closet Bolts and Flanges

Closet bolts, often included with new toilets, come in various lengths. It's important to select bolts that are long enough to extend slightly above the finished floor but not so long that they interfere with the tank. Flanges can be made of PVC, ABS, or cast iron. PVC flanges are common, durable, and easy to install, while cast iron offers superior strength but is heavier and more expensive. Ensure the flange is properly secured to the subfloor.

Installation Considerations

Before purchasing, measure the distance from the finished wall to the center of the closet bolts. This measurement, known as the rough-in, typically ranges from 10 to 12 inches. Ensure your new mounting hardware is compatible with your existing flange or the new one you plan to install. Always turn off the water supply to the toilet before starting any work.

Frequently Asked Questions

What is a wax ring's main function?
The wax ring's primary function is to create a watertight and airtight seal between the toilet bowl and the drainpipe in the floor. This seal prevents water and waste from leaking out during flushing.
How do I know what size closet bolts I need?
Closet bolts typically come in standard lengths. You'll need bolts long enough to pass through the toilet base and the flange, with a small portion extending above the finished floor. Ensure they are compatible with your toilet's bolt spread.
Can I reuse an old wax ring?
It is strongly recommended not to reuse an old wax ring. Once compressed, its sealing capabilities are compromised, and reusing it significantly increases the risk of leaks.
What is a toilet flange?
A toilet flange, also known as a closet flange, is a fitting that connects the toilet to the waste pipe system. It also serves as an anchor point to secure the toilet to the floor.
Are there wax-free toilet seals available?
Yes, wax-free seals are available and can be a good alternative, especially for DIYers. They often use rubber or foam gaskets to create a seal and can be more forgiving with minor floor imperfections or movement.
How do I fix a wobbly toilet?
A wobbly toilet is often caused by loose closet bolts or an uneven floor. Tightening the closet bolts can resolve this, but if the floor is uneven, shims may be necessary in addition to ensuring the mounting hardware is secure.
