Modernize your home's drainage system by removing outdated building traps. We replace them with modern two-way cleanouts for code compliance and free-flowing drainage.

Modernize Your Home's Drainage System

Homes built before the mid-20th century likely contain building traps -- outdated U-shaped sewer pipes that were originally designed to create a barrier against foul smells. Modern plumbing has individual P-traps on each fixture, making these main traps redundant and problematic.

Over decades, the old traps accumulate hair, grease, and debris, causing persistent backups. Their curved design prevents standard cleaning equipment from accessing the blockage. Tree roots are attracted to the stagnant water within the trap and can penetrate easily, potentially collapsing the entire sewer line.

Building Trap Removal FAQ

A building trap, also known as a main house trap, was traditionally used to create a barrier against foul smells from entering the home through the sewer line. It is a U-shaped pipe installed on the main drain line, typically found in homes built before the 1950s.
Look for two large brass caps near your basement floor drains or foundation walls. These are typically found in pre-1950s homes. If your home was built before this era and you experience recurring drain blockages, there is a good chance a building trap is the cause.
The trap's deep bend collects grease and hair over many years, creating persistent blockages. The curved design prevents standard cleaning equipment from accessing the clog. Tree roots are attracted to the stagnant water and can penetrate the trap, potentially leading to a complete sewer line collapse.
No. Modern individual fixture traps (P-traps) and vent pipes already provide complete protection against sewer gases. The building trap is redundant in homes with properly functioning P-traps on each fixture, which is standard in all modern plumbing.
A two-way cleanout is a straight pipe installation that replaces the old, curved sanitary trap. It provides bidirectional access for maintenance, allowing plumbers to clean and inspect the sewer line in both directions. This makes future drain maintenance faster and more effective.
