Because it doesn’t depend on a standing water seal, the HepvO removes common risks such as evaporation, siphonage and freezing-related failure, offering reliable odor control in tight installations and intermittent-use fixtures.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the HepvO valve stop sewer odors without water?\u003c\/h3\u003e\n\n\u003cp\u003eThe HepvO uses a one-way, self-sealing membrane that opens for wastewater flow and re-seals immediately after, preventing foul air from returning into the room.
