Bsc Preferred DIB20663 Plastic S-trap 1.5 Inches White

Product Description

The BSC PREFERRED DIB20663 is a 1.5-inch white plastic S-trap designed for bathroom lavatory drain assemblies. This replacement trap maintains the curved, S-shaped configuration that creates the water seal needed to block sewer gases from entering the living space. It ships with nuts and washers included, allowing for a complete installation without sourcing additional hardware. The white finish suits standard residential bathroom fixtures and blends with typical PVC drain components. Plumbers and experienced DIYers install this part as a direct replacement when the existing S-trap is cracked, leaking, or otherwise compromised.

This S-trap is suited for residential bathroom sink drain applications where a vertical drain outlet through the floor is present. It is not appropriate for installations governed by codes that prohibit S-traps, such as those following the Uniform Plumbing Code or International Plumbing Code, which require P-traps in most circumstances. Verify local code acceptance before installation. The 1.5-inch size corresponds to standard lavatory drain and tailpiece sizing found in most residential bathroom vanities.

Key Features

• 1.5-inch diameter fits standard lavatory drain tailpieces
• White plastic construction resists corrosion and is lightweight for easy handling
• Includes nuts and washers for a complete, tool-minimal assembly
• S-trap configuration creates the water seal that blocks sewer gas entry
• Sold individually, making single-fixture replacement straightforward

Compatibility

Designed as a replacement S-trap for residential bathroom lavatory drain systems with a 1.5-inch drain outlet. Verify local plumbing code compliance before installation, as S-trap use is restricted in some jurisdictions.

Installation Notes

Installation is typically performed by a licensed plumber or qualified DIYer familiar with local plumbing codes. Before replacing the trap, shut off the water supply and clear the cabinet space under the sink. Hand-tighten the slip-joint nuts first to align all components, then snug with slip-joint pliers — do not overtighten plastic fittings. Check for leaks at all joints after restoring water flow.
