Do you hear a constant “whooshing” sound in your bathroom? Are you using more water than usual? If so, chances are your toilet is running. A running toilet may seem like a minor issue, but it can actually lead to a significant waste of water and higher water bills. Plus, it can be a sign of a more serious plumbing problem. In this blog, we’ll discuss the common reasons why your toilet might be running and what you can do to fix it.

1) Faulty Flapper

The most common culprit of a running toilet is a faulty flapper. The flapper is the rubber seal that allows water from the tank to flow into the bowl when you flush. If the flapper isn’t sealing correctly, water will continuously leak into the bowl, causing your toilet to run. A simple fix for this issue is to replace the flapper with a new one, which is relatively inexpensive and easy to do.

2) Loose or Worn Out Fill Valves 

The fill valve is the mechanism that fills your toilet tank with water after you flush. If the fill valve is loose or worn out, it can cause water to continuously stream into the tank, leading to a running toilet. To fix this issue, you’ll need to tighten or replace the fill valve.

3) High Water Pressure

If you have high water pressure in your home, it may cause your toilet to run continuously. High water pressure can cause the fill valve to not shut off correctly, leading to constant water flow. In this case, a pressure regulator can be installed to remedy the problem.

4) Cracked Tank 

A crack in your toilet tank may also be causing it to run. A cracked tank won’t hold water, which leads to a leak and a running toilet. Unfortunately, the only fix for this issue is to replace the entire toilet.

5) Mineral Buildup 

Over time, minerals from hard water can build up in the valves and pipes in your toilet, causing blockages and leaks. This buildup can prevent the flapper from sealing correctly, leading to a running toilet. The fix for this issue is a professional cleaning or replacement of the affected parts.


A running toilet can be an annoyance but also a serious issue if left unchecked. If you’re experiencing a running toilet, it’s best to address it sooner than later.
