A no emission tank gauge has a housing having a valve connection extending from a bottom side of the housing, a gauge line within the housing, the gauge line having a plumb bob attached at a free end, a pulley attached within the housing and supporting the gauge line, the pulley configured to allow extension and retraction of the gauge line, and an actuator connected to the pulley and extending exterior to the housing and configured to actuate the extension and retraction of the gauge line via rotation of the pulley. The housing has a window in a wall of the housing facing a marked side of the gauge line. The valve connection has an opening sized to allow for passage of the plumb bob and the gauge line. The housing is sealed when the valve connection is connected to a valve to prevent escape of fluid.

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.

A water fullness alarm device may include an alarm switch, a bracket, and a float. The alarm switch may include an alarm switch body and a switch button disposed on the alarm switch body, where the switch button is adjacent to an elastic piece, and where a first end of the elastic piece is fixed on the alarm switch body and a second end of the elastic piece is free. The bracket may be rotatable, where a first end of the bracket is connected with the float, and where a second end of the bracket is propped against the elastic piece. The first end and the second end may be integrally formed such that the second end swings synchronously with the first end around an axis when the bracket rotates, where the second end drives the elastic piece to trigger the switch button when the bracket rotates.

A fully adjustable liquid tank float incorporates a float for use for gauging the amount of fuel or other liquid contained within a storage tank, the float being connectable to an adjustable lateral arm, which pivotally connects to a vertical structure, which secures to an adaptor that is mounted onto the top of the storage tank. The adaptor connects a transparent housing, which discloses an indicator of the amount of fuel remaining in the tank. The vertical structure is likewise adjustable in length. A flexible linkage connects with the indicator, and is adjustably secured with the lateral arm, to provide for a precise indication as to when the tank is full, partially full, or approaching empty.

A tank valve system comprises a main valve body, an overfill protection device (OPD), a gauge drive apparatus and a fuel level indicator. The OPD and gauge drive apparatus are configured to both be inserted through a narrow neck of a fuel storage tank prior to connecting the valve body to the neck. The valve body includes a primary fuel channel and a shuttle interface channel. The OPD includes an overfill float driving an overfill shutoff valve for controlling fluid flow from the primary channel into the tank. The gauge drive apparatus includes a gauge float, a shuttle, and an elongated extension body. The gauge float is movable with respect to the extension body between an uppermost position and a lowermost position, thereby driving the shuttle. The shuttle has a gauge actuation portion transportable within the shuttle interface channel to thereby actuate the fuel level indicator.
