Why Does My Toilet Bowl Keep Running? Here’s The Answer!
What To Know
- Over time, the fill valve can develop leaks or become clogged, causing the water level in the tank to rise too high and overflow into the bowl.
- If the flush valve seat is cracked, warped, or misaligned, it can prevent the flapper valve from closing properly and cause a leak.
- A loose or broken toilet handle can allow the flush valve to remain open, resulting in a running toilet.
The incessant sound of a running toilet can be both annoying and alarming. Understanding the underlying causes of this common plumbing issue is crucial for homeowners and renters alike. In this comprehensive guide, we will delve into the various reasons why your toilet bowl keeps running and provide practical solutions to resolve this vexing problem.
Leaky Flapper Valve
The flapper valve is a rubber or silicone seal located at the bottom of the toilet tank. Its primary function is to prevent water from flowing into the bowl when the toilet is not in use. A worn, torn, or misaligned flapper valve can cause a constant leak, leading to a running toilet.
Worn-Out Fill Valve
The fill valve is responsible for filling the toilet tank with water after each flush. Over time, the fill valve can develop leaks or become clogged, causing the water level in the tank to rise too high and overflow into the bowl.
Faulty Refill Tube
The refill tube is a small plastic tube that connects the fill valve to the overflow tube. A damaged or disconnected refill tube can allow water to leak into the bowl, resulting in a continuous flush.
Misaligned Flush Valve Seat
The flush valve seat is the surface that the flapper valve seals against. If the flush valve seat is cracked, warped, or misaligned, it can prevent the flapper valve from closing properly and cause a leak.
Clogged Overflow Tube
The overflow tube is a small hole located near the top of the toilet tank. Its purpose is to prevent the tank from overflowing if the fill valve fails. A clogged overflow tube can cause water to back up and flow into the bowl.
Worn-Out Toilet Handle
The toilet handle is connected to the flush valve. A loose or broken toilet handle can allow the flush valve to remain open, resulting in a running toilet.
Incorrect Water Pressure
Excessive water pressure can put strain on the toilet’s internal components and lead to leaks. If your toilet bowl keeps running, it is worth checking the water pressure in your home.
