Sink bottle traps act as a first line of defence against harmful bacteria, foul gases and clogging of the drain pipes.
Bottle traps are under sink piping with a bottle-like pipe of wide diameter that automatically fills itself after every use of the sink. This water in the bottle pipe acts as a water seal that does not let any debris enter the drain pipe. Also, the connection of sink pipe is ultimately to the sewer systems which acts as a pathway for harmful foul gases that are produced due to dirt in the sewer systems to escape through the sink and contaminate the entire area. With this water seal in place, these gases do not find a way out and remain trapped inside the pipes.

P traps under the sink are fittings that can be used in place of sink bottle traps. They do not have a bottle like pipe, instead, there is a long small diameter pipe in the shape of the alphabet P which gets filled with the water and performs the same functions as the bottle traps.
As under sink piping should be done keeping in mind the space under the kitchen, P traps are used where the sinks are not pedestal mounted so that there is ample space for their installation.
In case of pedestal mounted sinks, bottle traps for kitchen sinks are the best options.




Ajay pipes is a more than 50 year old business organisation, a leading name in the plumbing industry.
The company is a pioneer in the following products:

  • UPVC pipes
  • UPVC corrugated pipes
  • Handpumps
  • Reinforced Layflat hose
  • Reinforced suction hose

As plumbing & drainage systems are a crucial part of any physical infrastructure, components used in these systems must be of the best quality to avoid the hustle of replacing them in some time.

The most popular types of pipe and pipe fitting in use these days are PVC plastic pipes and fittings.

Fittings are the accessories that are used along with the pipes to form an effective plumbing & drainage system. Fittings are connected to the pipes either by rubber ring or using solvent cements.

What is SWR pipe?

SWR pipes are the PVC or UPVC pipes that are designed specifically for the drainage systems. SWR’s full form is Soil, Waste, and Rain water. So technically SWR pipe means the pipes and fittings used for soil, waste, and rainwater drainage.
A drainage system is highly important to discharge the wastewater from the land surface or sinks of living space or a building. The drainage system is very crucial to save crops and fertile lands from the overflowing water especially in India where monsoon brings heavy rainfall. Over the years people started to age in modern society and prefer compact housing. What they forget to concentrate on is a hi-tech domestic drainage system. This is where SWR pipes come into the picture.

Schedule 40 & Schedule 80 pipes


Introduction to Schedule pipes or simply Sch pipes

The meaning of Schedule in the world of piping systems is a reference to how heavy or light duty the piping component is. Pipe Schedule details the thickness of the pipe or more specifically the wall thickness of pipe with respect to different internal pipe bore diameter. Under this system the pipe diameter remains same for a particular nominal diameter designation. For eg a 2” pipe will have the same outer diameter for Sch 20 or sch 40 or sch 80 or sch 120 systems however the thickness will keep increasing in the same order.



PVC Plumbing Valve:

Valves are mechanical fittings that are used to control the flow in the plumbing systems, sometimes also used to change the direction of the flow.
Valves are very crucial in plumbing systems where flow control is required like motor pump connections, aquariums, swimming pools, industries, etc.
They are also essential to stop the flow whenever maintenance work needs to be carried out.
