A running trap sits in a horizontal drain line instead of under a fixture. Here is the South San Francisco guide.
The design
The trap is installed in the line itself, often in older homes or commercial drains.
The problem
Running traps are hard to snake and no longer meet most codes.
The replacement
A modern layout removes the running trap and vents the fixtures individually.
The call
Modernize the old line. Call 888-217-3585 and South San Francisco Plumbing Experts will match you with a South San Francisco pro.
