Buying Guide for Best Backflow Preventer For Sewer Line

Types of Backflow Preventers

Backflow preventers are devices used to stop contaminated water from returning back into the main water supply. Backflow preventers come in two main types: atmospheric vacuum breakers and double check valves.

Atmospheric vacuum breakers (AVBs) are designed to let air in when the pressure in the system is lower than the source pressure. This allows water to flow only one way, preventing backflow. AVBs can be installed at the end of a pipe or hose, or as part of a plumbing fixture such as a showerhead or faucet.

Double check valves (DCVs) are designed to provide an additional layer of protection against backflow by providing two independent check valves that must be opened before water can flow through them. DCVs are typically used in applications where higher levels of protection against contamination are required, such as commercial and industrial settings.

Factors To Consider When Buying A Backflow Preventer For Sewer Line

When buying a backflow preventer for your sewer line, there are several factors you should consider:

1. Size – Make sure you buy a backflow preventer that is the right size for your sewer line. If it’s too small, it won’t be able to handle the pressure from your system and could lead to backflow. Too large and it could cause excess debris to build up in your pipes and create blockages over time.

2. Installation – Make sure you understand how to install the backflow preventer, as some models require professional installation while others can be installed yourself with minimal tools and supplies.

3. Maintenance – Regular maintenance is essential for keeping your backflow preventer working properly, so make sure you understand what kind of maintenance is required for the model you purchase and how often it needs to be done.

4. Material – The material used for a backflow preventer will determine its durability and longevity, so make sure you choose one made from a sturdy material like brass or stainless steel that will last for many years with proper care and maintenance.

Cost

Backflow preventers vary widely in cost depending on size, type, material, brand name and other factors but generally range from $50-$500 or more for residential use depending on the model chosen and installation costs associated with it if professional help is needed . Commercial models tend to cost significantly more than residential versions due to their higher levels of protection against contamination but may save money in the long run due to their increased durability and longevity compared with residential models if properly cared for and maintained over time .

The best backflow preventer for your sewer line depends on the size of the pipe, the type of water supply, and your budget. While there are many different types of backflow preventers available, a quality one-piece unit is typically the best choice for most applications. These units are designed to provide superior protection against backflow and help safeguard your homes plumbing system. Be sure to choose a unit that is designed for your specific application, as this will help ensure it provides the most effective protection.
