Description
Designed for quality, reliability, and ease of installation, this resealing bottle trap is ideal for hand basins where space is limited beneath the fixture. The water seal provides effective protection against foul odours, while the resealing design maintains the seal even under extreme syphonic conditions.
The trap uses a simple hydraulic action to break siphonage by drawing air through the inlet and bypass columns when negative pressure occurs. Once normal conditions return, the remaining water automatically falls back to reseal the trap, eliminating the need for secondary ventilation. Secure seals and smoothly bedding threads reduce the risk of cross threading and help ensure a reliable, long-lasting joint.
