The seal is crucial for preventing leaks and ensuring a proper connection between the toilet and the waste holding tank. A worn or damaged seal can lead to unpleasant odors and costly repairs, so addressing this issue promptly is essential.
Identifying Signs of Wear
Before purchasing a new toilet seal, I recommend inspecting the existing one. I noticed that my toilet started to leak slightly, and there were unusual smells in my bathroom.
