Problems solved by technology

[0004] It is also known that the siphon effect that will develop in the trap causes the liquid in the trap to be sucked out of the trap, thus breaking the liquid-tight part

Embodiment Construction

[0044] First refer to figure 1 , the cross-sectional view shows a duct sealing device according to an embodiment of the invention, generally designated by the reference numeral 10 .

[0045] A plumbing seal 10 includes a passageway 12 having an inlet 14 suitable for connection to a waste outlet (not shown) and an outlet 16 suitable for connection to a sewage pipe (not shown). A one-way valve 18 is positioned between the passage inlet 14 and the passage outlet 16 , the one-way valve 18 being adapted to allow fluid to flow through the passage 22 in only one direction from the inlet 14 to the outlet 16 .

[0046] The pipe sealing device 10 also includes a water trap 20 configured to allow a liquid-tight portion 22 to be formed between the passage inlet 14 and the passage outlet 16 .

[0047] The water trap 20 includes a trap body 24 and a tubular partition 26 . The water trap body 24 includes an upper trap body portion 28 and a lower trap body portion 30 . The upper and lower ...

Abstract

A plumbing sealing arrangement (10) comprises a passageway having an inlet (14) adapted to be connected to a waste outlet (16) and an outlet adapted to be connected to a soil stack, a one way valve (18) located between the passageway inlet and outlet, the one way valve adapted to permit the passage of fluid through the passageway in one direction only from the inlet to the outlet and a trap (20) arranged to permit a liquid seal to be formed between the passageway inlet and the passageway outlet. In normal use, at least a portion of the one way valve is immersed in the liquid seal and in a described embodiment, an outlet of the valve is immersed in the liquid seal.

Description

technical field [0001] The present invention relates to an improved pipe seal for waste outlets. Background technique [0002] Traps, such as bottles or convoluted pipes, are widely used throughout the world to connect waste water outlets from sinks, bathrooms or showers, etc. to sewer pipes. Conventional traps include an inlet and an outlet, and define a pathway for liquid to flow from the inlet to the outlet. Conventional traps are designed so that, in use, liquid remains in the passage to provide a barrier between the inlet and outlet, preventing odors and gases from the sewer through the trap into the surrounding environment. [0003] While conventional traps are quite effective, there are also associated disadvantages. It is known, for example, that the liquid seal evaporates after a certain period of time, so that it is no longer possible to prevent the leakage of gas in the sewer pipe from the waste outlet. The problem is particularly acute where the waste outlet i...
