    Abstract: An apparatus for detecting wear in a flush valve includes at least one programmed controller. The flush valve comprises at least one pressure sensor and a valve element, and operates when an internal pressure causes the valve element to open. The controller is programmed to record at least one water pressure detected within the flush valve with the at least one pressure sensor after at least one operation of the flush valve, record a water pressure detected within the flush valve after a subsequent operation of the flush valve, and determine if the flush valve is faulty based at least partially on a comparison between the at least one water pressure detected after the at least one operation of the flush valve and the water pressure detected after the subsequent operation of the flush valve.

    Abstract: A flush valve system is provided having an inlet and an outlet, and a main valve element adapted for transition between a closed position and an open position is disclosed. The flush valve further includes a control chamber in communication with the inlet, and a vent outlet in communication with the outlet. The system includes a solenoid for establishing communication between the control chamber and the vent outlet to establish a pressure differential across a portion of the main valve element. The system also includes a power supply for energizing the solenoid, a deployable actuator in communication with the power supply, and a microprocessor in electrical communication with the main valve element. The microprocessor is adapted to determine a valve opening time, calculate fluid pressure based on the valve opening time, and deliver a predetermined quantity of fluid through the valve based on fluid pressure.

    Abstract: A toilet fixture is provided including an inlet pipe, a toilet bowl in fluid communication with the inlet pipe, an outlet pipe in fluid communication with the toilet bowl, a jet pipe in fluid communication with the inlet pipe and the outlet pipe, and a removable jet pipe assembly that connects the jet pipe to the outlet pipe. A foreign object strainer may be positioned in-line with the inlet pipe. A flush assembly may also include a flush valve, a vacuum breaker tube in fluid communication with the flush valve, a foreign object strainer in fluid communication with the vacuum breaker tube, and an outlet pipe in fluid communication with the foreign object strainer.

    Abstract: A system for monitoring flush valves includes a plurality of flush valves arranged in at least one restroom, each flush valve including a communication device configured to transmit flush valve data, and at least one controller arranged in a first flush valve and in communication with each other flush valve. The at least one controller is configured to determine a static pressure within the first flush valve, detect a second pressure within the first flush valve, determine that the second pressure is less than the static pressure, in response to determining that the second pressure is less than the static pressure, compare the second pressure with at least one other pressure associated with at least one other flush valve, and determine that the first flush valve is in need of servicing or replacement based on comparing the second pressure with the at least one other pressure.

    Abstract: A fence valve to catch material introduced into a pipe includes a housing defining a chamber and a catch plate disposed within the chamber that is movable with respect to the housing. The catch plate includes at least one magnetic region. The valve further includes a magnetic body in communication with at least a portion of the chamber, an indicator in communication with the catch plate, and a cable having a first end secured to the catch plate and a second end secured to a hook. The catch plate is transitionable from a first position in which the catch plate is disposed at a first location within the chamber, to a second position in which the catch plate is displaced from the first location. The catch plate is detachably held in the first position by interaction between the at least one magnetic region and the magnetic body.
