Where should a whirlpool bath tub pump be located concerning the trap?

• A. Above the outlet
• B. Above the weir of the trap
• C. Below the weir of the trap
• D. Beside the trap

Answer: (B)

The recommended placement of a whirlpool bath tub pump is above the weir of the trap. This positioning is crucial for ensuring proper drainage and preventing the backflow of wastewater into the tub. When the pump is situated above the weir, it helps maintain positive air pressure and prevents siphoning, thereby allowing the waste to flow smoothly through the trap without creating air pockets that could lead to clogs or drainage issues. By ensuring that the pump is above the weir, it utilizes gravity effectively, allowing the water to drain properly without compromising the trap’s ability to seal against sewer gases. This placement complies with plumbing codes and standards, which aim to enhance safety and functionality within plumbing systems. It’s essential for maintaining efficient operation while safeguarding against potential plumbing mishaps.
