How a Backflow Preventer Works

Understanding the Benefits of Backflow Preventers for Your Home

In this article, we will dive deep into the world of backflow preventers and explore the numerous benefits they offer to homeowners. Backflow preventers are essential devices that protect your home from potential water backup and sewage overflow during heavy rainfall or other sewer line issues. We will discuss how backflow preventers work, their importance in preventing costly damage, and highlight the Clever Cleanout’s innovative solution as a viable option. So, let’s explore the world of backflow preventers and discover how they can safeguard your home.

What is a Backflow Preventer?

Backflow Preventer and How It Works

A backflow preventer, also known as a backwater valve, is a device that allows water or sewage to flow only one way – out of your house. During intense rainfall or when city sewer lines become overloaded, these prevent the reverse flow of sewage or water, protecting your home from potential flooding and damage. They can be installed during the initial construction of a property or retrofitted into existing homes.

Why are they important?

Backflow preventers are crucial for homeowners, especially those with basements or ground floors below street level. The risk of water backup increases in such situations, and a backflow preventer acts as the first line of defense against potential sewage entering your home. By ensuring that water and waste only flow out of your house, backflow preventers prevent costly damage to your property and protect your investment.

How Does it Work?

The mechanics behind backflow preventers are relatively simple yet highly effective. Inside the valve, there is a small flap that remains open under normal circumstances, allowing water to leave your home and vent sewer gases. However, if water or sewage starts flowing backward into your house, floatation devices on each side of the flap lift it up and close, preventing any further entry. The clear top of the valve allows visual confirmation of its proper operation. Once the water has receded, gravity causes the flap to fall back into the open position, allowing normal flow to resume.

Introducing the Clever Cleanout Solution

One innovative and reliable option in the market is the Clever Cleanout. While backwater valves close off the flow completely, the Clever Cleanout provides a unique solution that allows wastewater to continue flowing out of your home while protecting it from sewage inflow. This means that even during a backup, wastewater will drain through the Clever Cleanout until the underlying issue is resolved, keeping your home safe from flooding. This versatile solution ensures you can continue using your home as normal during inclement weather without the risk of causing internal flooding.

The Benefits of Using a Backflow Preventer

Protecting Your Home

The primary advantage of a backflow preventer is its ability to protect your home from sewage backup during heavy rainstorms or sewer line issues. By preventing reverse flow, you minimize the risk of costly and damaging water intrusion.

Ensuring Health and Safety

Backflow preventers play a critical role in maintaining a hygienic environment. By preventing the backflow of contaminated water into your home, they safeguard the health and safety of your family members.

Long-Term Cost Savings

Investing in a backflow preventer is a wise financial decision. By preventing water damage and the need for extensive repairs, it saves you from incurring significant expenses down the line.

Peace of Mind

Knowing that you have a backflow preventer installed provides peace of mind during heavy rainfall or sewage line issues. You can rest easy knowing that your home is protected against potential flooding and its associated consequences.


Backflow preventers are invaluable devices that safeguard your home from potential water backup and sewage overflow. With their ability to prevent costly damage, ensure health and safety, and provide long-term cost savings, they are a must-have for homeowners. Whether you opt for a traditional backwater valve or choose the innovative Clever Cleanout solution, investing in a similar solution brings invaluable protection and peace of mind.
