Backflow Prevention and Certification Services in Spokane, WA
It’s a common misconception that plumbers are all the same. In reality, not all plumbers are certified to handle backflow prevention or devices. You’ll want to locate a service provider with certification. At Gold Seal Plumbing, we have exactly what you need!
What Do I Have to Know?
A backflow prevention system is designed to prevent water from flowing into the public water supply. As you may know, this situation is not ideal. Dirty water mixing with drinking water often leads to health complications. It’s important to test the system periodically and perform repairs as required.
What is 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.
Two Types of Backflow
There are currently two types of backflow 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.
How Can Backflow Be Avoided?
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.
Why Do Backflow Prevention Devices Have to be Tested?
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.
