How To Clean Toilet Siphon Jet?

In toilets, water enters the bowl through 2 channels; most of the water dumped into the bowl through a siphon jet parallel to the toilet trap. The remaining water enters the bowl through jets located on the rim of the toilet. They are positioned at an angle to create a swirling effect.

In the toilet bowl, the siphoned jets are small holes less than an inch wide. These tiny holes allow water from the tank to flow down into the bowl.
