SWR Full Form
Introduction
India knows Ajay Pipes as the most advanced PVC SWR piping system available, and we offer a complete range of SWR plumbing systems for all your needs.
Ajay Pipes became the first in India to incorporate a DM-seal jointing system, which we exclusively designed for easy, leak-proof, and cost-effective installation. As a result, the system ensures different installation options, impeccable quality finish, and perfect dimensional accuracy.
What is SWR pipe?
SWR pipes are PVC or UPVC pipes that manufacturers design specifically for 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 wastewater from the land surface or sinks of a living space or building. Moreover, the drainage system is very crucial to save crops and fertile lands from overflowing water, especially in India, where monsoon brings heavy rainfall. Over the years, people started to age in modern society and prefer compact housing. However, what they forget to concentrate on is a hi-tech domestic drainage system. This is where SWR pipes come into the picture.
What is the SWR System?
The SWR system is the system engineers design for soil, waste and rainwater drainage. Specifically, we design the SWR drainage system for quick and efficient removal of waste and debris without any blockage or leakage. Our SWR pipes are highly resilient, durable with high tensile and strength. In addition, our SWR pipes are immune to bacteria, fungi, and micro-organisms attacks and prove to be the perfect long term solution for building drainage systems.
What are SWR fittings?
Installers use SWR fittings for soil, waste and rainwater management. They are easy to install due to their lightweight.
We offer a complete range of pipes and fittings like,
- Ring-fit and Solvent-fit pipes
- Ring-fit and Solvent-fit fittings
- Big range of traps for both under floor and ceiling suspended installations
- High-performance solvent cement and lubricants
- Wash Basin P-traps and bottle traps
- Air admittance valves
- WC and Pan connectors
