3 Ways To Prevent Sewer Backflow

Posted on

A functional sewer system is a modern amenity that business owners often take for granted. When a sewer system is working correctly, waste flows from a commercial building to a municipal waste disposal system.

Flooding can cause a surcharge within the municipal system that limits the system's ability to process new waste. These surcharges result in backflow, which is raw sewage traveling back through your pipes and into your commercial space. Backflow can cause damage to your property and pose a serious health risk. It's important that you work with your plumber to prevent sewer backflow from plaguing your property in the future.

1. Sewer Check Valve

If you are looking for an affordable way to control backflow, then the installation of a sewer check valve might be the answer. These valves are designed to detect changes in your commercial building's drainage system.

When the pressure behind the valve builds, a flapper within the valve closes to prevent waste from moving back into your building. Sewer check valves offer short-term protection. Any significant sewage problems that last longer than a few days will need a more aggressive mechanism to prevent backflow problems.

2. Automatic Floodgate Valve

If you are doing business in an area where flooding occurs on a regular basis, you will want to install an automatic floodgate valve in your commercial plumbing system to protect yourself against backflow.

These types of valves are very sophisticated. They can provide you with maximum protection against backflow caused by a surcharge within your municipal sewer system.

An air chamber helps to monitor the pressure within your drainage system. Even the slightest change in pressure can be detected by a floodgate valve. When these pressure changes surpass safe levels, the valve automatically closes to create a barrier between your commercial space and the sewer system.

Backflow will be contained by the floodgate valve for an extended period of time, allowing your maximum protection during a flood.

3. Air Gap

An air gap should be present between all major plumbing fixtures and your commercial drainage system. The air gap is a vertical section of pipe that maintains air pressure. The pressurized air prevents raw sewage from creeping back up the drains in your sinks, washing machines, and other plumbing fixtures.

Although an air gap will not protect against the backflow created by a serious flood, these air gaps can provide daily protection against minimal amounts of backflow. For more information, contact a company like Silverdale Plumbing & Heating Inc.
