When it comes to plumbing, there are many elements that are essential to a well-functioning system. One of those elements is the trap, which is designed to prevent sewer gases from entering the home. There are two types of traps commonly used in plumbing: the S trap and the P trap. In this article, we will differentiate between the two and provide information on how to identify them.
S Trap
An S trap is a plumbing device that is shaped like the letter “S” and is typically used for drains located in bathrooms or kitchens. The purpose of an S trap is to prevent sewage gas from coming back into the home by maintaining a water seal. S traps are typically made of PVC or ABS plastic, which makes them easy to install and replace. They are also more affordable compared to other types of traps.
One way to tell if you have an S trap is to look under your sink or tub. If the pipe goes straight down and then makes a 90-degree angle, making an “S” shape, then you have an S trap. If your drain has an S trap, make sure that it is installed correctly and that there is no clog in the line. If there is a clog, it can cause the trap to fail and let sewer gases into the home.
P Trap
A P trap is a U-shaped plumbing device with a horizontal inlet and a vertical outlet. It is the most common type of trap used in residential plumbing. P traps are designed to prevent sewer gas from entering the house by maintaining a water seal. They are typically made of PVC or cast iron, making them durable and long-lasting.
To identify a P trap, look under your sink or tub. If the pipe comes out of the wall and then goes down into the drain, it is most likely a P trap. P traps are available in different sizes and shapes to fit various plumbing systems.
Identifying trap issues
Identifying whether you have an S trap or a P trap is the first step in recognizing potential plumbing problems. The following are some common issues you may face with either type of trap:
Smell from Drain
If you notice a foul smell coming from your drain, it could be an indication of a problem with your trap. The water seal that is being maintained by the trap may have dried up, which can allow sewer gases to enter your home. Pouring water down the drain can help replenish the water seal and potentially resolve the issue. If this does not resolve the issue, you may need a professional plumber to check and repair the trap.
Clogged Drain
If you have a clogged drain, it could be due to an issue with the trap. The trap may have become clogged with debris or failed due to age or damage. A clogged trap can cause water to back up into the sink or tub, which can be a significant inconvenience. You can try to use a plunger or drain cleaner to unclog the trap, but it may be best to call a professional plumber to fix the issue.
In conclusion
In summary, understanding the difference between an S trap and a P trap is essential in identifying potential plumbing problems. While both types are designed to prevent sewer gases from entering your home, they differ in design and function. If you encounter any issues with your trap, it is essential to address them immediately to prevent further damage or inconvenience.
