Home plumbing component that frees cupboard space by sitting very low beneath the basin, Wirquin Ultra-Flat Sink Trap. A tidier cupboard and fewer installation headaches follow when space is tight. Is the ultra-flat design and silicone membrane worth choosing over a standard trap?
⚡ At a Glance
- • Low profile: Height under sink 64 mm for installations with very limited clearance
- • Best for: Small kitchens and shallow-sink installations where cupboard space is at a premium
- • Not ideal for: Setups that require a conventional water seal to maintain a standing trap
Ultra-flat siphon sits 64 mm below the sink and uses a silicone membrane to allow flow then seal against odours. Push-fit connection with double-lip seals and a retaining ring creates a secure, tool-free joint.
Save cupboard space, thanks to ultra-flat siphon
Ultra-flat siphon measures 64 mm in height and compresses easily for low-clearance installations; the body can be folded to form angles up to 90 degrees for horizontal or vertical routing. The design removes the need for a traditional water reserve beneath the basin.
More usable storage under the sink and easier access for plumbing or storing cleaning items in confined cupboards.
Keep odours out, with a silicone membrane
A silicone membrane opens to let water and waste pass through and closes afterwards to block unpleasant odours, replacing a conventional water seal. The unit does not include a standing water trap.
Reliable odour control without a P-trap, useful where a conventional water seal is impractical due to height restrictions.
Fit quickly, thanks to push-fit and flexible routing
Push-fit connection requires no screws or gluing and relies on a double-lip seal and retaining ring to ensure a watertight join; the trap can be used with or without a threaded elbow and folded to 90° as needed. Flow rates are specified for both horizontal and vertical configurations.
Fast, tool-free installation that adapts to a variety of pipe layouts and minimizes time under the sink.
