What are the different types of sink traps
What is a trap for kitchen sink?
A trap for the kitchen sink is a device that helps to keep water from draining out of the sink and into the sewer. It has a curved part that catches water, and this water seals the drain so that sewer gas can’t escape and enter your home. Traps are often found in drains because they allow sewer gas to escape. Traps inside toilets serve the same purpose as any drain’s trap.
There are some different types of sink traps. The main difference is in the design of the curved part of the trap. Some traps have a flat design, while others have a curved design. Here you can find more about the different types of sink traps:
P Trap: The P trap is the most common type of sink trap. It has a curved part, and a horizontal part that connects to the vertical pipe. P traps work by trapping water inside the curved part of the trap so that sewer gas can’t escape from your home through drains. The trapped water seals the drain so that sewer gas can’t escape from your home through sinks and other drains in your home.
Q Trap: These plumbing traps are used in the latrine submerged storage room. It is similar to an S trap, but it is only being used on the upper story except for the ground floor.
S Trap: S trap is a pipe that curves into an ‘S’ shape to hold water and prevent sewer gases and bacteria. This is the most common type of sink trap. It is used in sinks, showers, and other drains in your home. The curved part of the trap holds water, and the horizontal pipe connects to the vertical pipe.
Gully trap: A gully trap is a basin in the ground that collects wastewater from your house before it enters the underground sewer. A water seal is placed on the basin to prevent smells from reaching the surface. Well-made gully traps will prevent sewage from flowing into your property or public pipes.
Floor Trap / Nahni Trap: The floor traps are also called Nahni Traps. They prevent foul gases from entering the building by providing a water seal.
Bottle Trap: The bottle trap is a style that emerged from Europe when older buildings had small bathrooms. The design uses the sink’s drain hole as its focal point, where the main pipe connects to it. This led to an upside-down bottle-like shape which gave off this look into the pipes below for natural light and good views of people inside their own homes.
Intercepting Trap: Intercepting plumbing traps are given at the intersection of buildings and public sewers. There is an interceptor sewer vent for foul gases, to keep sewage from entering a building sewer by providing a water seal.
Running Trap: Running trap is like a U, it’s specifically designed to allow liquid flow but prevent sewer gases from entering.
Drum Trap: Drum traps are an older and less popular plumbing component that help prevent larger items from entering the drain, but they can be dangerous if not installed correctly.
Grease Trap: A grease trap is a plumbing device designed to intercept most greases and solids before they enter a wastewater disposal system, ensuring that your pipes remain free of contaminants.

Average Cost of Different Types of kitchen sink trap
The average cost of a kitchen sink trap depends on various factors, such as the material used, the size and shape of the trap and installation costs. The average cost of a kitchen sink trap ranges from $15 to $50. Here are 5 kitchen sink traps that are available on the market.
What is the purpose of having a trap installed under a sink?
The purpose of having a trap installed under a sink is to prevent harmful materials from entering the public sewer. This includes grease, oil, waste, and most other types of liquids. A trap should be installed at the point where the drain pipes enter the public sewer.
The trap itself should consist of a pipe that extends horizontally into the ground, and another pipe on top that runs vertically down into the ground. The horizontal pipe is placed under or near the flooring in order to prevent any grease or other materials from falling through it and into the sewer system. The vertical pipe is placed in such a way as to allow access for waste disposal systems such as garbage disposals, dishwashers, and washing machines.
What happens if you don’t have a trap?
If there is no trap installed under a sink, grease and waste will be flushed into the public sewer system. This can cause pollution, foul odors, and health risks.
If you are having a toilet installed in your home, the plumber will most likely install a trap under the toilet. This is because it is the most common place for grease and waste to be flushed into the sewer system.
The answer to this question is not simple. Some drains do not need a trap. For example, the sink drain and the kitchen drain do not require a trap because they are covered by the sink and the dishwasher.
But drains that are connected to the public sewer system need a trap. For example, sinks, bathtubs, showers, and washing machines do not need a trap installed in order to prevent sewer back-ups.
How often should you clean your traps?
You will need to clean your traps more often if you have pets or children in the home that may be using the drain regularly. You will also need to clean them more often if you have had blockages in your drains before.
How do you open a trap under the sink?
