Filed:

Oct 9, 2020

Appl. No.:

17/067214

Inventors:

- Oviedo FL, US
Christopher Harrison - Deltona FL, US

International Classification:

E03D 11/18

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.

Inventors:

- Oviedo FL, US
Blaine Andersen - Maitland FL, US
Christopher R. Harrison - Deltona FL, US

International Classification:

F16K 37/00
E03D 5/10

E03C 1/05

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.

Inventors:

- Oviedo FL, US
Blaine Andersen - Maitland FL, US
Christopher R. Harrison - Deltona FL, US

International Classification:

F16K 37/00
E03D 9/00

Abstract:

A system for monitoring flush valves is provided, including a plurality of flush valves arranged in at least one restroom of a building, each flush valve of the plurality of flush valves including a communication device configured to transmit flush valve data, and at least one controller in communication with each flush valve of the plurality of flush valves. The at least one controller is programmed or configured to receive the flush valve data from each flush valve of the plurality of flush valves and determine if a first flush valve of the plurality of flush valves is in need of servicing or replacement based at least partially by comparing flush valve data for the first flush with flush valve data for at least one other flush valve of the plurality of flush valves. A method and apparatus are also disclosed.

- Oviedo FL, US
Blaine Andersen - Maitland FL, US
Christopher R. Harrison - Deltona FL, US

International Classification:

G05D 7/06
F16K 31/06

Abstract:

A system for optimizing a timing of a flush valve is provided. The system includes a flush valve comprising a flow area and a solenoid configured to open the flush valve, at least one pressure sensor configured to measure a pressure in the flush valve, and at least one controller in communication with the at least one pressure sensor and the solenoid. The at least one controller is programmed or configured to control the solenoid to open the flush valve for a flush time in response to a flush request, measure a pressure in the flush valve to obtain at least one flush valve pressure, adjust the flush time based at least partially on the at least one flush valve pressure, resulting in an adjusted flush time, and control the solenoid to open the flush valve for the adjusted flush time in response to a flush request.
