No one really knows how these plumbing tall tales began, but you’ve probably heard at least one. As your friendly plumbers, we feel like it’s our duty to inform you that these are all untrue, no matter how much your grandmother swears it works.

Myth: Throwing ice cubes down the garbage disposal will sharpen the blades.

Throwing ice cubes down the garbage disposal will not sharpen the blades, but it also won’t hurt anything. In fact, the ice cubes may help to clean the blades of your garbage disposal. So, if your sink is a little smellier than usual, throw a couple of ice cubes down the garbage disposal to help freshen it up.

Myth: Placing a brick in your toilet tank will help to save water.

We’re not really sure how this myth started, but putting a brick in your toilet’s tank will not help to conserve water. In fact, putting a brick in there could harm your toilet. The brick will deteriorate over time and possibly cause other parts of the toilet tank, like the flapper, to break. It can also displace too much water, resulting in you having to flush the toilet twice, defeating the purpose of the brick in the first place.

Myth: Toilet tablets containing bleach are safe and will keep your toilet clean.

A tablet containing bleach designed to sit in your toilet tank for an extended period of time is not safe. Within six months of using the tablet, all working parts of the toilet would be destroyed. Don’t shy away from using bleach to clean your toilet bowl, however. Just make sure to not let the product sit in the bowl for more than ten minutes.

Myth: Flushable wipes are safe to flush down the toilet.

Regardless of their misleading claim to be flushable, flushable wipes should not be flushed down the toilet. These wipes can cause major clogs and are wreaking havoc on city sewer systems all over the world. For more information on the impact of flushable wipes, please read our previous blog on the topic.

Myth: Based on which hemisphere you’re in, the toilet will flush a different direction.

The direction in which a toilet flushes is based on the way your toilet is designed, not the hemisphere you are in. This myth was most likely based on the Coriolis effect, which applies to much larger bodies of water not toilet bowls.
