Although you probably don’t think about how they work, toilets are a critical component of any household. When yours breaks down, it's bound to wreak havoc and make life difficult for everyone in your home. A common problem with toilets is a leaky tank. Midwestern Plumbing Service, a plumber based in Cincinnati, OH, explains what causes toilet tanks to leak.

What Causes Toilet Tanks to Leak?

1. Cracked Tank

If you’ve noticed a leak coming from your toilet, look for cracks along the bottom of the tank. If you identify the source of the leak and it's a crack in the tank, you’ll want to reach out to your local plumber as quickly as possible to prevent further deterioration. While professional repair is possible, your best option is usually a complete replacement. 

2. Broken Toilet Flapper

The flapper is the device in the tank responsible for keeping all the water down once the tank has been completely flushed. If it's not closing properly, your tank can easily overflow or constantly run. To see if it’s working correctly, take off the tank lid and flush the toilet, watching for whether any water leaks through the flapper. This issue can usually be repaired by a professional plumber.

3. Faulty Fill Valve

The fill valve, which refills the tank each time someone flushes the toilet, can get worn down over time and gradually become less effective. A bad fill valve can cause a host of problems for a toilet, including leakage or a weak flush. To regain proper water flow for your toilet, hire a plumber to replace the valve.
