Abstract

A drain cleaning and maintenance system, including a drain trap, having a first inlet in fluid communication with a drain of a plumbing fixture, a second inlet in fluid communication with the drain trap and a cleaning and maintenance assembly. The assembly includes a maintenance-assembly inlet in fluid communication with a source of pressurized liquid, and a maintenance-assembly outlet in fluid communication with the second inlet. An electronic valve has an open state allowing flow of liquid, from the maintenance-assembly inlet to the maintenance-assembly outlet, and a closed state blocking flow of liquid from the maintenance-assembly inlet to the maintenance-assembly outlet. An electronic controller is adapted to transition the electronic valve between the open state and the closed state, to allow liquid flow from the source to the drain trap via the second inlet.

IPC Classes  ?

• E03C 1/304 - Devices to facilitate removing of obstructions in waste pipes or sinks using fluid under pressure

Abstract

A drain pipe connector adapted to be disposed between a drain portal of a plumbing fixture and a sewage pipe. The drain pipe connector includes a first unidirectional valve adapted to be in fluid communication with the drain portal, and a drain trap in connected to the first unidirectional valve and adapted to be connected to the sewage pipe. The first unidirectional valve has a closed operative orientation, in which the first unidirectional valve forms a seal between the drain portal and the drain trap, and an open operative orientation which enables flow of fluid from the drain portal, via the first unidirectional valve, into the drain trap. The first unidirectional valve is normally closed, and when liquid drains into the first unidirectional valve, pressure applied by the liquid transitions the first unidirectional valve from the closed operative orientation to the open operative orientation, thereby enabling the liquid to flow into the drain trap.

IPC Classes  ?

• E03C 1/298 - Odour seals consisting only of non-return valve
• E03C 1/122 - Pipe-line systems for waste water in buildings
• E03C 1/282 - Odour seals combined with additional object-catching devices

Abstract

A drain pipe connector adapted to be disposed between a drain portal of a plumbing fixture and a sewage line, including a first unidirectional valve adapted to be in fluid communication with the drain portal, and a drain trap connected to the first unidirectional valve and adapted to be connected to the sewage pipe. The valve has a closed operative orientation, in which the valve forms a seal between the drain portal and the drain trap, and an open operative orientation which enables flow of fluid from the drain portal, via the valve, into the drain trap. The valve is normally closed, and when liquid drains into the valve, pressure applied by the liquid transitions the valve from the closed operative orientation to the open operative orientation, thereby enabling the liquid to flow into the drain trap.
