An in-line water trap located in the line of the flow of waste through a generally straight line or bend is provided for. Typically, the water trap comprises a fluid conduit having a first end, a second end and a passage between the first and second ends; and a vessel having a closed end, an open end and a skirt between the closed and open ends, the lobed vessel further having an inner surface defining an inner volume and an outer surface, the inner surface attachingly engaging an outer wall of the fluid conduit in so doing defining a flow path between the passage, the inner volume of the lobed vessel and the outer surface of the lobed vessel, in use, a fluid level inside the inner volume of the lobed vessel being substantially in communication with the second end of the fluid conduit to form a fluid seal. |

1. An in-line water trap comprising:
a fluid conduit having a first end, a second end and a passage between the first and second ends; and a resiliently deformable lobed vessel for receiving the conduit having a closed end, an open end and a skirt between the closed and open ends, an inner surface of the closed end, open end and skirt defining an inner volume, at least part of the inner surface attachingly engaging an outer wall of the fluid conduit in so doing defining a flow path between the passage, the inner volume of the lobed vessel and an outer surface of the lobed vessel, so that in use, a fluid level is substantially maintained inside the inner volume of the lobed vessel to form a fluid seal, wherein the lobed vessel is resiliently deformable in response to pressure difference across the closed end of the lobed vessel, between an open position, wherein the closed end of the lobed vessel is spaced from the second end of the fluid conduit facilitating fluid flow between an inner volume of the lobed vessel and the passage of the fluid conduit, and a closed position, wherein the closed end of the lobed vessel abuts and seals against the second end of the fluid conduit thereby hindering fluid flow between the inner volume and the passage. |
