Common Questions About Backwater Valves

A backwater valve is a mechanical device installed in your main sewer line that allows sewage to flow out but prevents it from flowing back into your home. It acts as a one-way gate that closes automatically when sewage tries to flow in the wrong direction.
If your home is in a low-lying area, has experienced previous sewer backups, is connected to a combined storm/sanitary sewer system, or if you have finished basement areas, you should consider a backwater valve. Many insurance companies now require them.
The valve is typically installed on your main sewer line inside your basement or crawlspace, before your plumbing connects to the municipal sewer system. Installation requires access to this pipe.
No, a properly installed backwater valve allows normal drainage while only activating when backflow occurs. You shouldn’t notice any difference in your drainage during normal operation.
We recommend annual inspection and maintenance to ensure proper operation. The valve should be cleaned and tested to verify it will function correctly during an emergency.
