Why Is My Flush Valve Leaking? Here’s The Solution You Need!

A leaking flush valve can be a frustrating and wasteful problem. Not only does it waste water, but it can also lead to higher water bills and even damage to your bathroom. If you’re wondering why your flush valve is leaking, you’re not alone. This is a common problem that can be caused by a variety of factors. In this blog post, we’ll explore the most common causes of flush valve leaks and provide step-by-step instructions on how to repair them.

Common Causes of Flush Valve Leaks

There are several reasons why a flush valve may start to leak. Some of the most common causes include:

• Worn or damaged flapper valve: The flapper valve is a rubber seal that sits at the bottom of the toilet tank. When you flush the toilet, the flapper valve lifts up to allow water to flow from the tank into the bowl. Over time, the flapper valve can become worn or damaged, which can cause it to leak.
• Damaged fill valve: The fill valve is responsible for filling the toilet tank with water after each flush. If the fill valve is damaged, it can cause the tank to overfill, which can lead to a leak.
• Loose or cracked flush valve: The flush valve is the assembly that connects the toilet tank to the bowl. If the flush valve is loose or cracked, it can cause water to leak from the base of the toilet.
• Corroded or clogged water supply line: The water supply line is the pipe that brings water to the toilet. Over time, the water supply line can become corroded or clogged, which can restrict the flow of water to the toilet and cause a leak.
