An early version of the flush toilet was invented as early as 1596, but didn’t see widespread use until 1851. Today it’s hard to imagine life without indoors toilets. Since the toilet is the fixture in your home that sees the most use, you want to make sure that it is in good shape. Here are a few things that you want to check up on.

A toilet that runs continuously wastes a lot of water. There could be a few different reasons for this, such as improper installation of the flushing mechanism, a cracked seal or just old age. Many times the fix will be to replace the failing parts.

If there are cracks in the tank or the bowl, this is a serious problem, and it might be time to replace the entire toilet.

The water-line connection could be leaking, causing damage to your bathroom floor or create a breeding ground for mold. It should be refastened or replaced, if necessary.

No part of your toilet should be loose or wobbly. Make sure that it is fastened properly.
