The term “backflow” refers to an undesirable condition – this is the reversal of the flow of some type of fluid or even suspended solids back into a drinkable or clean water supply. To prevent this from occurring is possible through the installation of a backflow preventer. While they are available in metal, some companies prefer to manufacture and/or install a PVC backflow preventer.
PVC Backflow Preventers
Cross connection describes the point at which drinkable and non-drinkable water join. Positioning backflow preventers correctly prevent the intermingling of contaminated or wastewater with the potable water from occurring by allowing the fluid to flow in one direction only. This preserves the integrity of the water supply system. The correct placement of these special types of check valves on water piping systems is often a requirement under the national, state and/or local plumbing codes.
The decision to install a PVC backflow preventer in preference to a metal one has a solid basis. PVC offers certain advantages over other materials. It is:
- Capable of lasting years
- Highly resistant to corrosion
- Provides accurate control of the potential contamination problem
- Very affordable
To those who favor this type of backflow preventer, the material, and the product combine to reduce the risks of cross-contamination. In doing so, PVC backflow preventers help to maintain high-quality water for those who use it.
The intent of all backflow preventers is to preserve the reliability of the water supply. To accomplish this, its most common applications are as a component of any municipal water supply system. Specifically, a backflow preventer commonly is a part of the water supply piping.
PVC Backflow Preventer
Backflow preventers play a significant role in keeping our potable water supply safe. Available in different materials, the preference for PVC does offer some advantages. It addresses both economic and functionality issues. A PVC backflow preventer is able to combine both affordability with durability and operational effectiveness.
