There is described an apparatus for determining a level of a liquid to be contained in a container, comprising: a body extending along a longitudinal axis, the body being insertable within the container; and a level sensor unit secured to the body for detecting the level of the liquid along the longitudinal axis of the body.

A device adapted for installation onto a toilet overflow pipe to indicate a leaking condition of a toilet flush valve. The device having a stem portion with a diameter configured for receipt within an interior diameter of a toilet overflow tube. The device including a housing forming a reservoir for collection of water prior to entering the overflow tube. The reservoir including a cavity for the placement of a water soluble pigment, wherein the pigment is dissolved within water in the housing and into the overflow tube. An alternate embodiment of the device, includes a stay member configured to support a ball float member in an off condition.

A flushing station is provided. The flushing station includes a connection piece for a hot water pipe, a connection piece for a cold water pipe, a collecting tank with a siphon for draining the water, pipes at the connection pieces which conduct the water from the connection pieces into the collecting tank at least one sensor per pipe a control unit connected to the sensor, a valve actuatable in the pipes, wherein the control unit is coupled to the actuatable valve and the actuatable valve can be opened by the control unit for flushing the hot or cold water pipe. According to the invention, a flow restrictor and a flow straightener are integrated in each of the pipes.

A monitoring system for monitoring a water level in a plumbing element. The monitoring system has a sensor unit, which includes at least one sensor for detecting a measured value and with the aid of which a water level in a receiving space of the plumbing element may be ascertained. A plumbing element is also provided that comprises a receiving space for accommodating water and at least one water outlet for emptying the water from the receiving space.

An overflow system for determining a level of a liquid to be contained in a container, which comprises a body extending along a longitudinal axis, the body being insertable within the container; and a level sensor unit secured to the body for detecting the level of the liquid along the longitudinal axis of the body.

This device when adapted to an ordinary bath tub, converts the tub into a system that prevents spilled water resulting from the process of taking a bath, from spilling onto the bathroom floor. This device captures the water that ordinarily would have fallen on the floor and redirects it to a reservoir tank, for holding. This tank or water holding device, stores the water until it is quickly and easily disposed by dumping it back into the tub's drainage system. There is no other system that has the ability to keep the bathroom floor completely dry when either taking a shower or a bath. With a series of shield, water trough and hoses, the water that ordinarily would have become a safety hazard on the floor, is quickly channeled off to a drain line, there to a reservoir tank from which the water would be disposed. The device is attractive, non-intrusive and light weight. It is also detachable after installation and is completely portable and transferrable.

A standing water alert system comprises two conductive wires or a float extending into a drain and connected to an audible or visual alarm that is triggered when standing water is present. A drain alert system and method comprises a plurality of sensors, such as pressure or acoustic/vibration sensors, at various locations within a plumbing or fluid filtration system to measure pressure or an acoustic profile at that location and a control system to compare the measured parameters to a threshold value or range and/or to other measured parameters from nearby sensor locations. A signal is sent to a remote user or computer or an alarm is triggered when the comparison shows a potential blockage, a leak, or indicating that a filter needs to be replaced or cleaned. An approximate location of the blockage, leak, or fouled filter is determined by comparing measured parameters at nearby sensor locations.
