Understanding the Need for Replacement
When I realized my Gerber toilet was leaking, I knew I needed to replace the tank. Over time, wear and tear can affect the tank’s performance, leading to problems like cracks or rust. Recognizing the signs early can save me from more extensive plumbing issues.
Assessing Compatibility
Before diving into the replacement process, I made sure to check the compatibility of the new tank with my existing toilet bowl.
