For building code compliance, what type of material should be avoided when constructing water closet bolts?

When constructing water closet bolts, using soft metals is not advisable due to their lack of durability and susceptibility to deterioration over time. Soft metals, such as lead or low-grade aluminum, can easily deform or corrode when exposed to moisture and the conditions typically present in a bathroom environment. This can lead to failure in holding the toilet securely in place, resulting in leaks or instability.

On the other hand, corrosion-resistant materials are preferred because they can withstand the humid conditions and potential exposure to water without degrading. Similarly, standard steel, when treated or coated to prevent rust, can also be suitable provided it meets the necessary corrosion-resistance requirements. Plastic may be appropriate in certain contexts, but it must meet the strength and compliance standards outlined in building codes.

Thus, avoiding soft metals is critical for ensuring the longevity and reliability of water closet installations, aligning with building code requirements.
