Troubleshooting Toilet Flange Installation Problems
Installing a toilet flange can be daunting for those new to plumbing. Some common problems occur during toilet flange installation.
Here are some of the most common problems and how to troubleshoot them:

- The flange is too high or too low: If the flange is too high or too low, the toilet will not sit properly, causing leaks and instability. You can use an extender or a spacer to raise or lower the flange to the correct height.
- The bolts are over-tightened: Over-tightening the bolts can cause the flange to crack or break. It can also cause damage to the toilet. To avoid this, tighten the bolts until they are snug, but do not over-tighten them.
- Using the wrong type of flange: Different flanges are available, and using the wrong type can cause problems. Make sure you choose the right flange type for your toilet and plumbing system.
