Understanding the Backwater Valve

Saskatoon is no stranger to heavy rainfall and potential flood risks. Homeowners face the ever-present danger of basement flooding, which can lead to significant property damage and financial loss. In the battle against these threats, one crucial line of defense stands out: backwater valves. In this blog post, we will explore the importance of having a backwater valve to protect your home.

A backwater valve, also known as a backflow prevention valve or a sewer backup valve, is a simple yet highly effective device installed in your home’s plumbing system. Its primary purpose is to prevent sewage water from flowing back into your home during heavy rainfall or sewer backups. The valve is strategically positioned in the main sewer line or branches serving basement plumbing. It allows wastewater to flow out but closes upon a backup to prevent reverse flow.

Mitigating Basement Flooding

Basement flooding can be devastating and can cause extensive damage to your property and possessions. In Saskatoon, where heavy rainfall and overwhelmed sewer systems are common, the risk is even more pronounced. However, by installing a backwater valve, you significantly reduce the likelihood of basement flooding.

During heavy rainstorms, the municipal sewer system can become overloaded, unable to handle the excess water. When this happens, sewage water can flow backward through the pipes and into your basement. This can lead to contamination and significant damage. A backwater valve acts as a barrier, closing off the pipe and preventing the sewage water from entering your home.

Financial Protection

Apart from the physical damage caused by basement flooding, the financial implications can be overwhelming. Repairing or replacing damaged flooring, walls, furniture, and appliances can quickly escalate into a substantial financial burden. By installing a backwater valve, you can protect your home and possessions, potentially saving thousands of dollars in restoration costs.

Peace of Mind

Knowing that your home is equipped with a backwater valve brings peace of mind, especially during heavy rainfalls or when you’re away from home for extended periods. With this valuable device in place, you can be confident that your basement will remain dry and your property protected from sewage backups. The sense of security provided by a backwater valve allows you to focus on other aspects of your life without constantly worrying about potential flood damage.

Local Regulations and Insurance Considerations

In Saskatoon, as in many other municipalities, the installation of a backwater valve is highly recommended for existing homes and is required in new homes by local building codes. Municipalities recognize the importance of these devices in safeguarding homes against basement flooding. Moreover, having a backwater valve installed may also have a positive impact on your home insurance coverage. Insurance companies often view proactive measures such as backwater valve installation favorably, potentially leading to lower premiums or expanded coverage options. Many insurance companies require homes to have these installed to maintain insurance coverage (check with your insurance company).


For Saskatoon homeowners, protecting their properties against basement flooding is a top priority. With the frequency of heavy rainfalls and the risk of overwhelmed sewer systems, installing a backwater valve becomes an essential step. The investment in this simple device not only guards against costly property damage but also provides peace of mind and compliance with local regulations. Don’t wait for disaster to strike; take proactive measures to secure your home with a backwater valve and ensure a safer, more secure future.
