Patent number: 11725374Abstract: 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.Type: GrantFiled: July 9, 2021Date of Patent: August 15, 2023Assignee: PHYSICLEAN LTD.Inventor: Nir Nahum

Patent number: 6341618Abstract: A method for installing plumbing fixtures in a multi-story building having a waste stack includes a stop valve between the waste output of each fixture and the waste stack, the valve allowing the waste water to flow from the fixture toward the waste stack, but preventing flow from the waste stack back into the plumbing fixture. The valve has a cylindrical body, a lower assembly and an upper assembly, which together form a water-tight structure, with threaded outlets in each assembly. Within the body there is suspended a stop ball having a diameter larger than that of the ball seat in the upper outlet. When water attempts to back up from the waste stack in the direction of the stop valve, the ball is forced against the upper seat and blocks the water flow.Type: GrantFiled: May 30, 2001Date of Patent: January 29, 2002Inventor: Rudolph V.
