If you’ve ever experienced issues with a toilet that is leaking, you know that it can be very stressful. Knowing what causes leaking toilet issues can help you to keep your toilet better maintained and prevent it from leaking in the future.
Our Expert Plumbing technicians have assembled some helpful information about some of the leading causes of leaks in toilets and how you can maintain your toilet in order to prevent issues in the future.
Nine times out of ten, if your toilet is excessively running water, it is either because of an issue with your toilet flapper or fills valve.
- The flapper is located in the tank and is responsible for controlling how much water flows from the tank into the bowl when the toilet is flushed.
There are three types of toilet flappers and seals in use today:
- Flush canister “Seals” – Class 5 series toilets with canister valves require class 5 canister seals. These types of seals fight conditions that cause leaks, resist chemical attacks, and withstand wear. Certified to ASME (American Society of Mechanical Engineers) Standards.
- Flush valve “Tank ball” – As the name implies, the tank ball is a rubber ball that sits in the opening of the flush valve with a chain attached to it. When the toilet is flushed, the chain pulls the ball up allowing water to flow from the tank into the toilet bowl. If the chain is not correctly sized, however, the ball will not function properly.
- Flush towers – Tower-style flush valves have a round rubber gasket instead of a flapper to keep water in the tank, and during the flush, the entire tower/canister lifts upward to release water down through the tank opening.
While flapper and seal issues are the most common cause of leaking toilets, if you have replaced the flapper and your toilet is still running, it may be that the Flush Valve is to blame.
One possible cause of a leaking toilet is that the water level in your tank is too high. Luckily, adjusting the water level of your tank is easy enough that it can be done in a matter of minutes with little more than a screwdriver, whether you need to replace the fill valve or adjust the float. While it can be done by yourself, you are much better off contacting a professional to make sure this is done properly and won’t require more repairs in the future.
Here are a few tips to help you maintain a functioning toilet without leaks:
- Keep your toilet clean by cleaning it regularly with a mild cleaner.
- Avoid using chemical cleaners in your toilet tank, as they can be corrosive and damaging to different parts of your toilet.
- Inspect the elements within your toilet’s tank about every 6 months to make sure everything is working properly.
- Don’t flush anything besides human waste and toilet paper down your toilet. Do not flush sanitary wipes or baby wipes.
