Backflow preventers are an essential component of a property's plumbing system, as they help prevent contaminated water from entering the system and posing a risk to public health. With so many types of backflow preventers available, choosing the right one for your property can be a daunting task.
In this blog, we'll explore what you need to consider when choosing a backflow preventer, and provide some new ideas and advice to help you make the right decision.
Understanding Backflow Preventers
Backflow preventers are designed to prevent backflow from occurring in a plumbing system. Backflow occurs when the pressure in a plumbing system is reduced, allowing contaminated water to flow back into the system. Backflow preventers work by creating a barrier between the contaminated water and the potable water supply.
Types of Backflow Preventers
There are several types of backflow preventers available, including:
Reduced pressure principle backflow preventers (RPPBs)
Double check valve assemblies (DCVAs)
Pressure vacuum breakers (PVBs)
Double check valve assemblies with atmospheric vent (DCVAs-AV)
Factors to Consider When Choosing a Backflow Preventer
When choosing a backflow preventer, there are several factors to consider, including:
Water Pressure: The water pressure in your plumbing system needs to be considered when choosing a backflow preventer. Some backflow preventers are designed for high-pressure systems, while others are designed for low-pressure systems.
Flow Rate: The flow rate of your plumbing system also needs to be considered. Some backflow preventers are designed for high-flow applications, while others are designed for low-flow applications.
Contamination Potential: The contamination potential of your plumbing system also needs to be considered. Some backflow preventers are designed to prevent contamination from specific sources, such as cross-connections or backpressure.
New Ideas and Advice
Consider a Combination Backflow Preventer: If you're looking for a backflow preventer that can handle multiple types of backflow, consider a combination backflow preventer. These devices can handle both backpressure and back-siphonage.
Consider a Backflow Preventer with a Built-In Air Valve: If you're looking for a backflow preventer that can handle air intrusion, consider a backflow preventer with a built-in air valve. These devices can help prevent air from entering the plumbing system and causing problems.
Consider a Backflow Preventer with a Built-In Check Valve: If you're looking for a backflow preventer that can handle both backpressure and back-siphonage, consider a backflow preventer with a built-in check valve. These devices can help prevent backpressure and back-siphonage from occurring.
Conclusion: Choosing the right backflow preventer for your property can be a complex task, but by considering the factors mentioned in this blog, you can make an informed decision. Remember to consider the water pressure, flow rate, and contamination potential of your plumbing system, and don't be afraid to ask for help from a professional if you're unsure about which type of backflow preventer to choose.
