Water closets must be secured to the floor using which type of hardware?

Water closets, commonly known as toilets, must be secured to the floor using a durable and corrosion-resistant type of hardware to ensure stability and longevity. Brass bolts are typically the correct choice for this application because they provide a strong, reliable connection that can withstand the environment of a bathroom, where exposure to moisture is common.

Brass is known for its strength, resistance to rust and corrosion, and ability to hold up well in wet conditions. This makes it particularly suitable for securing plumbing fixtures like water closets. Additionally, brass bolts can effectively handle the mechanical stresses that occur when the fixture is used, ensuring that the toilet remains securely attached to the floor over time.

In contrast, the other materials present various limitations. Stainless steel is indeed a strong option but may not be as commonly used for this purpose due to cost considerations and compatibility with certain toilet materials. Plastic bolts, while resistant to corrosion, may not provide the same level of structural integrity required for a secure installation of heavy fixtures. Aluminum bolts are generally not recommended in plumbing applications due to their susceptibility to corrosion and potential weakening over time. Thus, brass bolts emerge as the preferred hardware for securing water closets to the floor.
