Showerhead devices incorporate sensors to control bath fill levels. Showerheads have interchangeable attachments, including bristle attachments. Oral care devices are attachable to standard shower arms. Pump devices allow various lotions and fluids to be used in conjunction with showers. Shower organizing devices provide for ordered storage and access to accessories. Bathtub spouts including sensors and valves to control bathtub filled levels.

The invention relates to a heat recovery unit to transfer heat from a gray water source discharged from a bath or a shower to preheat fresh cold water supplying a bath, a shower, a boiler system or hot water heater. The heat recovery unit comprises an inner tube, an outer tube, a non-return valve, an anode, deflectors as well as associated piping and fittings. Fresh water from a pressurized public network or well flows through the inner tube while the gray water flows between the inner and outer tubes. The non-return valve installed in the fresh water pipe prevents contamination of the drinking water system. A translucent pipe may be installed in a section of the gray water piping system to detect any leaks. An insulated jacket may be placed around the unit to reduce heat loss. The heat recovery unit may be used in domestic, commercial, industrial and institutional buildings.

A thermal expansion compensating device has a conduit with a first opening and a second opening for connection to a first pipe and a second pipe of a hot water system, respectively, the first and second pipes being formed by removing a section from a length of pipe of the hot water system. A pre-tensioning force is applied to the device to axially displace the first opening from the second opening until after connection of the openings of the pipes. A resiliently deformable pipe segment defines a portion of the conduit between the first opening and the second opening and is resiliently deformed to a tensioned position by the application of the pre-tensioning force. Once the hot water system is activated, the pipes axially thermally expand such that the first opening moves towards the second opening and the pipe segment moves from the tensioned position towards a rest position decreasing the stress on the device.

A portable hygiene station that is configured to be transportable so as to facilitate execution of hygiene protocols such as but not limited to hand washing at locations wherein utility infrastructure is unavailable. The portable hygiene station includes a frame wherein the frame is manufactured from a plurality of support members. The frame includes an upper portion and a lower portion that are integrally formed. The lower portion of the frame has mounted therein a first tank and a second tank. Mounted to a support shelf on the lower portion is a power supply and a pump that is electrically coupled to the power supply. The pump is configured to transfer fluid from the first tank into a basin member via a faucet member. Fluid from the basin member is subsequently transferred to the second tank. A top member provides coverage of the station and further has a photovoltaic panel.

A processor may receive an input dataset. The input dataset may include a plurality of waterpipe components and one or more performance factors of the waterpipe system. A processor may generate a digital twin of the waterpipe system using the input dataset. A processor may simulate, using the digital twin, one or more features of the waterpipe system. The simulating may include a forecast having one or more predicted conditions associated with the waterpipe system.
