Various embodiments of a reverse thermostat for use in restricting hot water in a plumbing system from being delivered to cold water fixtures are disclosed.

Water and space saving bathroom components especially useful for a comfort station. Included are a novel toilet having a cistern with a sink in combination with the toilet, a novel waterless urinal and a hand sanitizer dispensing station. The sink is an integrally formed sink into the top of the cistern and has a drain formed into the sink for draining effluent from the sink into the toilet cistern. A faucet is installed in the surface of the sink to provide a clean water source for hand washing and the like that generates grey water after washing. The waterless urinal can be plumbed and mounted to a comfort station wall or on a mobile stand, while the hand sanitizer dispensing station may be adapted for multiple dispensers. The dispensers may be mounted at different heights to accommodate adults, children and disabled persons in wheelchairs.

Systems, methods, and devices relating to urinal, in some examples having a movable portion able to pivot from a generally closed to a generally open position. The urinal may have a drain line engaged with a proximal end of the funnel for conveying urine and rinse water into a sewer line or a toilet bowl and a rinse line coupled with a water supply for rinsing urine therein. The urinal may be movable with the assistance of one or more sensors that may automatically signal other electrical or mechanical components to move one or more portions of the urinal, and may be include elements that seal portions of the urinal when not in use or during cleaning to reduce gas or liquid escaping from the urinal system.

For combination with a flush toilet water tank having a side wall, a pond water receptacle integrated with said tank side wall at the exterior of the tank, the receptacle opening upwardly, there being a water passage through the tank side wall, whereby pond water in the receptacle has a gravity determined top level at approximately the same level as water in the tank, and a removable cover extending over water in the receptacle, protecting against contaminated pond water gaining access to tank water.

A toilet tank washbasin and faucet system that rests on top of a toilet tank is described by way of example. The faucet dispenses water intended to fill the toilet tank over a drain that leads into the toilet tank. The faucet is useful to a person for washing their hands with the water dispensed from the faucet to advantageously provide a second use of the water before flushing down the toilet. Generally described is a basin that sits atop an open toilet tank. A faucet having a nozzle end is attached to the basin via a keyed member that a) positions the nozzle end over a drain in the basin and b) prevents rotation of the faucet when attached to the basin, the drain leads into the toilet tank. Water is provided to a flexible tube that attaches to a bowl refill tube. The flexible tube extends through the faucet and terminates essentially at the nozzle end.

The present disclosure discloses an anti-siphonage water storage device, a sanitary water supply device, and a sanitary cleaning device. The anti-siphonage water storage device is set in a cleaning water path of a sanitary cleaning device, and the anti-siphonage water storage device comprises a water tank for storing cleaning water. The water tank is disposed with a water inlet structure and a water outlet structure, and the water tank is disposed with an overflow structure. A water outlet surface of the water inlet structure is higher than an overflow surface of the overflow structure.

The invention relates to a cistern, in particular an in-wall cistern, for a toilet or urinal, with a drain valve which has a closure body which can be lifted from a closed position into a flushing position. The closure body is designed as an overflow pipe and has a seal which rests tightly on a valve seat in the closed position, with at least one water intake line, with a valve assembly for letting in drinking water present in the water intake line, with a water discharge line for discharging the drinking water let in by the valve assembly, and with a controller which generates a control signal for actuating the valve assembly as a function of a sensor signal and/or when a predefined time interval has been exceeded since the last withdrawal of drinking water from a cold water or hot water line connected to the water intake line. The valve assembly lets in water from the water intake line as a function of the control signal. According to the invention, the water discharge line is designed in such manner that it discharges the drinking water let in by the valve assembly directly into the overflow pipe. The cistern according to the invention makes it easier to maintain the drinking water hygienic, offers the possibility of carrying out required hygienic flushes with relatively low water consumption and enables a hygienic flushing independent of the flushing water level.

Systems, methods, and devices relating to urinal, in some examples having a movable portion able to pivot from a generally closed to a generally open position.
