A water supply mechanism includes a switching part that executes switching between water supply and water shut-off, a manual operation valve on the switching part that is capable of a manual operation thereof, and a pushing member that pushes the manual operation valve to provide a valve-closed state. The manual operation valve is pulled in a direction opposite to a pushing direction of the pushing member to provide a valve-opened state. The manual operation valve includes a plunger, an external cylinder member that encloses the plunger, a first engaging point in the external cylinder member, and a fixation part in the external cylinder member that fixes the plunger in the valve-closed state or the valve-opened state. The plunger moves beyond the first engaging point as the manual operation valve is pulled, and is fixed in the valve-opened state as a pull of the manual operation valve is released.

A check valve comprising, between an inlet end and an opposite outlet end along a common longitudinal axis, optionally an adapter arranged between the inlet end and a seal seat, a seal seat formed by a rigid scaffold, a closure element formed by an elastic closure part, optionally a stop ball, and optionally a stop that can be latched to the scaffold, wherein the scaffold and the closure part are shaped to match one another in the region of the seal seat, and the closure part is tensioned against the scaffold in the region of the seal seat in the rest position and is retained therein, wherein the scaffold has breaches in the region of the seal seat, and the closure element is formed in one piece with a venting device

Toilet like device, which saves water through the separation of solid and liquid depositions, in a hygienic, comfortable, simple, autonomous and aesthetic manner. It's composed by a main toilet body, which has an open space within itself, connected to the main toilet bowl, a space which is open in its front and superior sides. This space works as a water and urine recipient, the water and urine come from the urinal, which at the same time works as a drainage for urine and water. This space also works as a liquid recipient when the urinal is in vertical position, since it is very likely that, after a liquid deposition, the urinal needs to be raised towards a vertical position, for various different reasons. Any liquid remaining in the urinal falls into this space, without going into the rest toilet body, and much less onto the user.

An example vacuum-assisted toilet includes a toilet bowl including an outlet. The outlet of the toilet bowl is fluidly coupled to a first flush valve, for example, using a first pipe. The first flush valve is fluidly coupled to a second flush valve that is positioned downstream from the first flush valve. For example, the first flush valve may be fluidly coupled to the second flush valve using a second pipe. The second flush valve is fluidly coupled to a vacuum source. The vacuum source may include, for example, a holding tank having a vacuum pressure therein, a vacuum pump, or any other suitable vacuum source.

An intermittent fluid delivery system includes a fill tank and a batch tank which is connected to the fill tank via a first pump and a first hose. The fill tank holds a first quantity of fluid. The batch tank holds a second quantity of fluid, which is lesser than the first quantity. The first pump delivers fluid from the fill tank to the batch tank. A second pump delivers fluid from the batch tank to a receiving tank.
