Illinois Plumbing Code Practice

Except for repairs, cement mortar joints are acceptable. True or False?

1. True

2. False

The correct answer is: False

Cement mortar joints are not generally considered acceptable for applications other than repairs in plumbing systems according to the Illinois Plumbing Code. This is primarily because cement mortar is not designed to withstand the various pressures and conditions found in plumbing infrastructure. While it can be useful for certain types of repairs where structural integrity is at stake, utilizing cement mortar for joints can lead to failures in the system over time due to issues such as flexibility, movement, and the inherent brittleness of cured cement. For typical plumbing installations, more suitable materials and methods that ensure flexibility and resistance to vibration and pressure changes are required. Thus, the assertion that cement mortar joints are acceptable would be considered false according to the standards set forth in the Illinois Plumbing Code.
