Are S Traps Still Used?
What is all the talk about “S” Traps? Yes, they are still in use. You wouldn’t think that we would still find “S” traps during a home inspection but it’s a common defect in older homes. These traps are prohibited by the Florida Plumbing Code.
What is an S Trap?
The mechanical purpose of the trap is to hold water to prevent sewer gases containing viruses and bacteria from entering the home through the drain. With an “S” trap drain, the trap is easily siphoned dry with each use and the water seal no longer exists.
1002.3 Prohibited Traps
The following types of traps are prohibited:
- Traps that depend on moving parts to maintain the seal.
- Bell traps.
- Crown-vented traps.
- Traps not integral with a fixture and that depend on interior partitions for the seal, except those traps constructed of an approved material that is resistant to corrosion and degradation.
- “S” traps.
- Drum traps.
