Sewer Backflow Valve Installation

24/7 Emergency Service Call856-858-1965



A sewer valve, often referred to as a backwater valve, sewer backflow preventer, or check valve, is a device installed in a sewer line or drain system in a building to prevent sewage from flowing back into the building.

When heavy storms or flooding occur, the municipal sewage system may become overwhelmed, leading to the possibility of sewage backing up into your home’s sinks, toilets, and bathtubs due to increased pressure. This can pose significant health risks and property damage.

To combat this, installing Sewer Backflow Preventers is a proactive measure. These devices are engineered to prevent contaminated water from re-entering your home’s clean water supply, ensuring water flows only in one direction – out of your home.
