A backwater valve is located at the exit point of the sanitary pipe under your home. The valve allows waste water to flow from your property out to the main sanitary sewer towards the street. In conditions when waste water flows back toward your home, the valve closes and prevents it from re-entering.
Luckily, your back water valve’s lid is removable and you can look inside to inspect how the system is functioning. Check to see that the flapper is intact, and moving freely. Furthermore check the gaskets on both the flap and lid. If you suspect something is not operating correctly call us immediately and we can come to your home for a detailed inspection.
Your home insurance provider may want to know if you have a backwater valve installed, especially if you’re located in a high risk area for a sewage backup. Not sure if you have one installed? The easiest way to know is to check your home inspection report. Some insurance providers require you to have one installed in order to be eligible to receive coverage caused by sewage related damage. Going through the necessary steps to ensure you have one installed and maintain it properly is a lot easier than dealing with the damage associated from not having one.
