Introduction of S Traps
An S trap is a U-shaped portion of a plumbing pipe that is designed to trap liquid or gas to prevent unwanted flow, particularly sewer gases from entering buildings while allowing waste materials to pass through. It is important to note that S traps have a major flaw that could cause a water siphon, removing the water built up in the curve, opening the seal, and allowing sewer gas to pass through, which is why they are no longer allowed in plumbing code.
Basic Design of an S Trap
An S trap is a type of plumbing trap that is commonly used in residential and commercial buildings. It is named after its distinctive shape, which resembles the letter “S”. The trap is designed to prevent sewer gases from entering the building while allowing waste materials to pass through.
The basic design of an S trap consists of a U-shaped pipe that is connected to the drainage system. The top of the trap is connected to the sink or fixture, while the bottom is connected to the sewer line. The U-shaped pipe is filled with water, which creates a seal that prevents gases from escaping into the building.
The water in the trap acts as a barrier, trapping any gases that may be present in the sewer line. This helps to maintain a healthy and odor-free environment inside the building. If the trap becomes dry or the water seal is broken, sewer gases can enter the building, causing unpleasant odors and potentially posing a health risk.
Historical Use In Plumbing
The S trap has been used in plumbing systems for many years and was a common type of trap in older buildings. However, it has since been replaced by the P trap, which is considered to be more effective and reliable.
In the past, S traps were used because they were easier and cheaper to install. However, they were found to have several drawbacks, including the potential for the water seal to be broken and the risk of siphoning, which could lead to the release of sewer gases.
Due to these issues, S traps are no longer permitted in many plumbing codes and regulations. Instead, P traps are now the preferred choice for most plumbing installations. P traps have a more effective design that prevents siphoning and maintains a reliable water seal.
While S traps may still be found in some older buildings, it is recommended to replace them with P traps to ensure proper functionality and prevent any potential health hazards.
