What could result from over tightening the bolts on a water closet during installation?

  1. Water leakage

  2. The bowl or tank breaking from stress

  3. Improper alignment

  4. Clogging issues

The correct answer is: The bowl or tank breaking from stress

If the bolts on a water closet are over tightened during installation, it can result in the bowl or tank breaking from stress. This is because over tightening the bolts puts too much pressure on the ceramic material, causing it to crack or break. Water leakage, improper alignment, and clogging issues are not likely to be caused by over tightening the bolts, making them incorrect choices. Water leakage could be a result of faulty gaskets or loose connections, improper alignment could be due to incorrect installation techniques, and clogging issues could be caused by a variety of factors such as old pipes or foreign objects being flushed.
