Water Seal: The trap holds a small amount of water, which acts as a barrier to prevent odors and gases from the sewer from coming back into the room.
Telescopic Adjustment: The telescopic feature allows the trap to be adjusted vertically, making it easier to align with the waste pipe under the sink, especially in tight or awkward spaces.
Applications:
Bathroom Sinks: Commonly used in bathrooms where the trap needs to be adjusted to fit within cabinetry or other tight spaces.
Kitchen Sinks: Also used in kitchens, particularly where the waste pipe alignment might be off-center or where space is limited.
