What is a backflow valve?
A backflow valve is a safety mechanism installed in your plumbing pipes to prevent wastewater or stormwater from flowing back into your home or business. It acts as a barrier to stop dirty water, mud, or unwanted liquids from backing up into your drains or pipes in the event of a drainage system backup. This backflow phenomenon can occur due to heavy rainfall, blockages in sewers, or issues in the public plumbing network.
When a backflow valve is installed, it allows water to flow normally towards the sewers, but it blocks any reverse flow, thus preventing flooding in areas such as the kitchen, bathroom, or even the basement. This not only protects your property from water damage but also from health risks associated with the intrusion of wastewater.
As you can see, installing a backflow valve is essential to protect your home or business from sewer backups and flooding risks. A poorly installed or non-compliant device can compromise its effectiveness, putting your property at risk and potentially leading to significant damage and costs. For optimal protection, it is crucial to hire experienced plumbers for the installation of your backflow prevention device.
Types of backflow valves
There are several types of backflow valves, each with its own specifications depending on the application. Here are the main types we install at PUM:
Ball check valve
This type uses a ball that automatically closes when water begins to backflow. It is ideal for installations in basements or residential sewers.
Swing check valve
A flap that closes under water pressure, preventing water from flowing back into the pipes. This type of backflow valve is very common in residential installations.
Floor drain backflow valve
Installed directly in the floor drain, this device prevents water backflow into basements or garages. It is an ideal solution for homes with a low basement.
Backflow valve for exterior drains
This model is specifically designed for outdoor drainage systems, preventing rainwater or wastewater from flowing back into your home after heavy rainfall.
Each type of backflow prevention device has its advantages, and we will help you choose the one that best suits your needs based on the location and configuration of your pipes. Whether you need a manual or automatic valve, we have the solution that works for you to ensure the protection of your property.
