Different types of Plumbing traps./15 types of plumbing traps.

Let us go through the different types of traps used in plumbing works.

1. Bottle trap:

These traps are used in wash basins & sinks to collect heavier waste & prevent the entry of foul gases. Bottle traps are installed when the plumbing system has no separate built-in traps. 

 2. P -trap:

This trap resembles the English alphabet P in its shape. They are installed in the water closet, basins & sinks to prevent the entry of foul gases into the house. The water retained within the curved shape acts as a barrier to the entry of bad odors & gases.

P- trap is generally used to provide the outlet at the wall level of the building.

3. S- trap:

They work similarly to the P-trap in retaining the entry of foul gases. The S-trap is used when the outlet is needed at the floor level of the latrine. The S- shape makes the exit end parallel to the inlet of the trap.

4. Q - trap:

Q-trap is used for the upper-floor levels rather than the ground-floor water closet. The selection of a Q-trap or P-trap for the installation mainly depends upon the available space beneath the pan or sink.

5. Nahani trap:

They are also known by the name floor traps. They are installed at the floor level to collect the wastewater from the bathroom, washroom, kitchen sinks, etc. They contain grating or jali at the top surface to prevent the entry of solid waste into the drainage system.

6. Gully trap:

These traps are provided at the exterior plumbing system of the building. They are enclosed with masonry chambers at the connection points. The grating cover at the top retains all the solid waste & prevents them from entering the drains.

 They are the junction point to collect the wastewater coming from all the areas such as washbasins, kitchen sinks, wash areas, bathrooms, etc.

The water seal within the gully trap acts as a barrier to the entry of cockroaches & foul gases.

7. Running trap:

They are usually installed in public buildings, where a single trap is utilized for all types of washing sinks & basins. 

8. Drum trap:

It consists of drum shaped vessel to hold a larger volume of water. They are mostly used in bathtubs & laundry sinks. 

The main advantage of a drum trap is, it never allows the water to siphon out from the pipeline due to the larger water depth.

9. Bell trap:

A bell trap is installed in the outdoor plumbing lines coming out of garages, patios, passages, etc. to trap the floor-level draining water. It seals through the water stored within the cup having a bell-shaped cover that dips into the retained water. 

10. Building trap:

This is the U-shaped bend, provided at the exterior of any building's main sewer line. In comparison to the P or Q traps, they are the bigger type of water trap to handle the larger flow of waste liquid.

They act as a secondary line of defense against the sewer gas & vermins.

11. Intercepting trap:

 The manholes constructed within the building area to provide the connection to the public sewer line are known as interceptor manholes. These traps are attached to the intercepting manholes or chambers to prevent the entry of unwanted gas & odor from the public sewer system.

They are usually required in apartments or larger buildings, where a large amount of wastewater gets collected.

12. Low-level bath trap:

They are ideal for bathtubs & other shower units, where there is less space for the outlet connection.

13. Grease trap:

The purpose of providing these traps is to separate & filter the grease from the liquid & retain the grease. They can be cleaned at regular intervals by opening the top cover. 

This type of trap is mostly installed in the plumbing system of food manufacturing units.

 

14. Straight through trap:

In a straight-through trap, the inlet & outlet openings are in line with each other. This helps for neater plumbing installation within a minimal space.

 They are used as pedestal basin traps to fit within the pedestal coverings.

15. Silt trap:

It allows silt & debris to separate from the water & settle at the bottom. This helps to remove unwanted materials from contaminated water before entering the drainage system.

They are installed in the stormwater systems to trap the sediment from blocking the drainage line due to the sudden gush of rainwater.
