Backwater Valves – Do I Need One?

 
One of the questions we are often asked is: ”We have never flooded during storms, do I really need a backwater valve?”

This is a very valid question that is almost impossible to give a 100% accurate answer to. However, what we can advise you of are the potential issues when combined with the correct weather conditions that could possibly put your home at risk of flooding. We hope that the information that we are about to provide will help in making the decision of whether you should install a backwater valve or not.

The main concern as to whether a backwater valve is needed or not is the weather. Flash storms, heavy downpours and above normal rainfall amounts are all contributing factors when it comes to basement flooding.

One of the world’s most trusted forecasters is the Farmer’s Almanac. As seen below, these are the predictions of precipitation from November 2014 to October 2015. As you can see the months of April, May, July and October they are predicting higher than normal rainfall.

Now that we’ve established that there’s potential for the weather trends of the past few years to continue let’s determine if your home could possibly be at risk.

 

Over the past few years have any of your neighbours basements flooded during heavy rain falls?

If you answered yes to the above question, this would indicate that you are living in a potential flood zone.

 

Have any of your neighbours that have previously flooded, installed a backwater valve in their home?

If you answered yes to the above question, this puts your home in jeopardy of flooding when a major storm hits the area. The reason being, is that the water that filled the homes during the last storms, will be redirected by their backwater valves further up the system. This can potentially affect the unprotected home, even if they were not flooded previously.

 

Has the City, Municipality or Region that you live in implement programs, rebates or funding for the installation of backwater in your area?

If the City, Municipality or Region that you live in are offering programs, rebates or funding for the installation of backwater valves in your area, there is a perfectly good reason why they are doing this. Their engineers and upper management have predetermined the risk of residential flooding in your area and are working towards preventative measures to greatly reduce or eliminate residential flooding in the affected communities.

 

If you answered yes to any of the above questions, then the potential risk for your basement to flood during a major storm is present. With the proper installation of a backwater valve by a certified professional, you can greatly reduce your risk of flooding.
