Its called a Belleville spring/washer and it works by pressure.
The washer is curved and when the nut is tightened down against it, the washer flattens out. But due to the heat treated memory of the metal, it wants to remain curved and pushes back against the nut which creates a locking effect between the threads on the nut and the threads on the bolt.
does the front work? if the front DOES work, it may just be the hose to the back has a leak/hole.
Belleville washers, also known as coned disc springs, conical spring washers, disc springs, Belleville springs, or cupped spring washers, are types of springs shaped like a washer.
Spring washer - is used to keep the nut from loosening due to vibration by Appling pressure between the bolt and nut to stop it from undoing
It has a giant spring on it, and when you sit on it the spring pulls back small amounts at the time, causing it to swing back and forth.
A spring washer is used to apply a constant tension force between two connected components, helping to prevent loosening due to vibrations or thermal expansion/contraction. It also helps distribute the load evenly and provides some level of insulation from friction.

as you jump on the Pogo stick you press down on a spring at the bottom. Then the spring propels you back upwards .
Prevents the spring from going into the filter.
The stored energy in a stretched-out slinky spring toy is potential energy. As the coils are pulled apart, work is done to stretch the spring, and this work is stored in the spring as potential energy. When the spring is released, this potential energy is converted back into kinetic energy as the coils snap back together.
When you pull the handle a washer is lifted and the water goes down into the toilet and at the same time the cistern fills up once the washer is back in place from the flushing mechanism
