Backflow Questions Answered
Backflow is the flow of water or other liquids or gases in a direction opposite to the intended flow. It can occur in various systems, including plumbing, irrigation, and industrial processes. Backflow can have many negative consequences, including drinking water contamination, property damage, and health hazards. This blog post will discuss backflow and answer common questions about backflow, how it’s prevented, and backflow testing.
What Causes Backflow?
There are two main types of backflow. Back pressure happens when there is too much pressure in the main line. Back siphonage is caused by a separate drainage system, often caused by secondary backflow. This is more likely to occur during the wastewater treatment process.
Several things can cause backflow, including a malfunctioning water main, pressure differences, and extended power outages. Broken water mains cannot keep up with household water usage. This frequently causes leaks inside the home. A malfunctioning water main can also cause sewage to flood the basement if it is not repaired.
Pressure differences also stem from the main line. One of the most obvious ways a homeowner can tell if they have backflow is if the pressure has been altered. This will often become noticeable in the shower. In-house pressure differences cause backflow to release from both the bathroom and kitchen faucets. Backflow may come from an outside system or be attached to the sewer and can cause serious health concerns.
Extended power outages are more likely to cause bacteria inside the plumbing system. Because stagnating water creates mold, this quickly becomes a health risk. Household members should avoid taking showers for safety reasons until the system is fixed. Scalding water may randomly blast from the faucets.
How Can Backflow Be Prevented?
Backflow preventers are commonly used devices and methods that can be installed within the existing pipelines. An air gap or one-way valve is left open so clean water entering the home will flow in the right direction. In the event of a potential backflow crisis, the valve is designed to close automatically. A backflow prevention device will protect household water from contamination.
However, homeowners who do not regularly maintain their plumbing system and backflow preventers may have issues with double-check valves or other backflow prevention devices. These valves and other methods are designed to prevent reverse-flowing water. If they are not inspected, it will not be clear whether they are working and can continue preventing backflow.
When Is Backflow Testing Needed?
Backflow can lead to severe health issues, so it’s essential to have backflow prevention devices tested regularly. Backflow devices should be inspected and tested annually by a licensed plumber. This involves temporarily shutting off the water service to check the valves or other backflow preventers. A backflow tester will assess pressure changes by measuring the flow of water. This can be completed in less than two hours.
If a backflow device is broken, the plumber can help fix or replace it to protect the home’s water from contamination due to backflow. Technicians will handle the job from start to finish so homeowners can have peace of mind that their water will stay safe and that the household’s health is protected.
