Understanding Backflow

Backflow is an unwanted reversal of water flow. Typically, the source of water is contaminated, such as sewage. This pollution then flows into the public water supply, causing issues.

There are currently two types of back flow to consider:

  • Backpressure – Occurs when the system experiences higher pressure than water supply systems, allowing contaminants to enter the potable water system.
  • Backsiphonage – Occurs when negative or reduced pressure exists within the water supply, allowing contaminants to be drawn into the drinking water supply.

Avoiding and Testing for Backflow

Avoiding and Testing for Backflow

There are multiple devices on the market designed for backflow prevention, including reduced pressure backflow preventers and non-return valves. Depending on your situation, we can install one or the other.

A mechanical backflow prevention device, like many plumbing systems, utilizes an internal seal, springs, and various moving parts. Over time, these systems may break down, corrode, or rust. Repairs could be frequent, depending on use and age.

We’ll help prevent a problem by testing and repairing the prevention device thoroughly.
