Running toilets are almost always caused by a worn flapper, a misaligned chain, or a faulty fill valve-simple fixes that often go overlooked. From experience, we've learned that ignoring them leads to wasted water and higher bills, so quick action saves time and money. This has reinforced the importance of addressing small maintenance issues early, both at home and in our projects. It's also taught us to keep common replacement parts, like flappers or fill valves, on hand. Proactive upkeep prevents bigger problems and makes overall home maintenance more manageable.
