Common Reasons Why Toilets Leak

A toilet is used multiple times a day in most households, so it is essential to have a toilet that is in good working condition. While toilets are quite durable and are designed to last for many years, it is possible for problems to develop. One common problems found in toilets is leaking. If you discover that your toilet is leaking, it is normal to be concerned, however, in most cases, a plumber can diagnose what is causing the leak and then make the necessary repairs. Some of the most common reasons for a toilet leak include the following.

Problems with the Seal at the Base of the Toilet

When a new toilet is installed, a seal is placed around the base of the toilet in order to secure it and help keep it in the proper position. The seal also plays an important role in keeping the area around the base of the toilet dry. If you discover that the area around the base of your toilet is wet, the problem is most likely a loose seal or a seal that has worn out. The good news is that replacing a faulty seal typically stops the leaking.

Toilet Bowl Crack

The material used to manufacturer toilets is quite strong, but that doesn't mean that it is immune to damage. Since many toilets are used for many years before they are replaced, it is possible for a crack to form in the toilet bowl. If your toilet bowl has a very small crack that is caught early, it can most likely be patched by a plumber. But, if your toilet bowl develops a large crack that is leaking a lot of water, your best bet is to have your old toilet removed and have a new one installed.

The Tank is Not Properly Connected to Bowl

Many people do not realize that a toilet consists of two major parts, the tank and the bowl, which are tightly connected together to ensure that the toilet functions properly. Your toilet has nuts, gaskets, and bolts which keep the two pieces of the toilet together. But, over time it is possible for a nut, gasket, or bolt to wear out or become loose. When that happens, your toilet will begin leaking in the area where the toilet bowl and tank connect. Some companies, like Marcum Plumbing Services, Inc., know that typically, this type of issue can be solved by a plumber—tightening or replacing the faulty part will take care of the problem.
