As a plumber, you understand how vital backflow prevention is for the safety of your community. But did you know several devices are available to assist you with this task?
In this blog post, accurate Backflow Testing & Plumbing will discuss five backflow prevention devices. We will also provide information on how each device works and its benefits. So if you’re looking to learn more about backflow prevention, be sure to read on!
Hose bib vacuum breaker:
Most outdoor taps are equipped with hose bibs, allowing the owner to use a garden hose to wash the car, water the garden or grass, and perform other water-related tasks. Most modern hoses have a built-in vacuum breaker to avoid backflow. However, because older homes may lack an exterior tap, they should be safeguarded with a hose bib vacuum breaker.
Keep the vacuum breaker attached to the hose bib to avoid back-siphonage caused by a lack of water pressure.
Clean water and contaminated water should never mix! Each should always pass through its pipe. An air gap is an excellent technique to avoid this form of backflow.
In plumbing, an air gap is an open, vertical area or gap between the water break and the flood level of a fixture.
Wastewater is routed via the air gap, preventing pollution. Air gaps ensure that your pure water supply is not contaminated by sewage.
Vacuum pressure breakers:
Vacuum pressure breakers are the most recent testable backflow prevention devices, and they are typically used with underground sprinkler systems to avoid back-siphonage. They have a check valve within the unit to prevent pressure drops. The spring at the assembly’s top opens an intake valve, allowing air into the system, breaking the suction effect, and allowing water to flow downstream and escape the pipe. Many guidelines require that underground sprinkler systems be regularly tested with pressure vacuum breakers to ensure good operation.
Dual check valves:
These are commonly used on residential premises to prevent backflow from unprotected cross-connections in your plumbing. Although many laws do not allow dual check valves as part of a cross-connection control program due to their limited use, homeowners must take the required precautions to reduce the harm caused by thermal expansion. If you have this device installed in your pipes, you should contact our professional for guidance on avoiding this.
Automatic flood gate valve:
These devices are highly successful in stopping wastewater and preventing any associated harm. They are entirely automated and run on air pressure. Once closed, a stainless steel knife-edge fully steps backwater for as long as required.
Some older homes lack backflow preventers, putting everyone who lives there in danger. If you notice that your home lacks a backflow prevention device, you should contact Accurate Backflow Testing & Plumbing in Bradenton, FL.
