Installing a backwater valve is an effective way to safeguard your home and prevent a sewage backup from happening. A backwater valve is a mechanical device installed in a plumbing system to prevent sewage or wastewater from flowing back into the property during instances of heavy rainfall, flooding, or when the municipal sewage system malfunctions or becomes overloaded.
The valve operates by allowing sewage to flow out of the property as usual, but when there is a reverse flow due to high water levels outside, the valve automatically closes to block sewage from re-entering the property's plumbing system. Once the water level equalizes and the risk of backflow diminishes, the valve reopens to allow normal drainage to resume. Essentially, the backwater valve acts as a one-way gate, ensuring that sewage flows out of the property but cannot flow back in, thereby protecting against potentially damaging and hazardous backups.
