How a Toilet Works – (Anatomy of a Toilet)

“My toilet is clogged or has a weak flush, it doesn’t always empty the bowl when I flush it….”

The above quote is a very common symptom reported by many clients. Would it surprise you to know that about half of the time the toilet isn’t clogged at all! Take a look at the picture below: Notice the spot marked “trap,” this is the place where water & waste travels on its way to the sewer drain pipe. Technically the toilet is only “clogged” when an obstruction exists inside the trap preventing passage. Note the hollow area around the bowl. When a toilet is flushed, water sitting in the tank rushes into and around these hollow chambers and then enters the bowl via water jets. The main water jet (aka “siphon jet”) is usually at the bottom of the toilet bowl.

Anatomy of toilet

An older, poorly performing toilet can have clogged jets and/or obstructed jets preventing the water from entering the bowl as needed. This causes weak flushing toilets & toilet bowls that don’t empty all the way. Additionally, if the water level inside the tank is too low this results in an inadequate amount of water for a proper flush.

An old plumbing trick called “the bucket test” can narrow the possibilities.  Simply fill a 5 gallon bucket of water and pour it into the toilet bowl expeditiously. If the toilet bowl revives the water with no problem or back up – it’s more than likely your toilet is in need of repair or replacement.
