Waterless Self-Sealing Wastewater Trap – Odour-Free, Compact & Maintenance-Free

Say goodbye to unpleasant smells and messy water seals with our Waterless Self-Sealing Wastewater Trap — the smart, space-saving solution for modern caravans, RVs, and compact plumbing systems.

Unlike traditional P-traps that rely on standing water to block odours, this innovative unit uses a silicone self-sealing membrane that opens automatically when water flows through, then closes tightly when not in use. This creates an airtight seal that prevents greywater odours, gases, and insects from entering your living space — without needing any water to function.

Compact and easy to install both vertically or horizontally, the waterless trap is ideal for caravans, motorhomes, boats, and tiny homes where space and efficiency are key. With no stagnant water to evaporate or freeze, it’s also perfect for off-grid or seasonal setups, requiring virtually no maintenance.
