Is your basement at risk for backflow flooding?


We’ve experienced some rainy weather lately. As we’ve learned over the years as licensed plumbers in Louisville, Kentucky, heavy rain often means basement backups and flooding. One contributing factor to basement flooding is backflow caused by sanitary sewer overload.

The Kentucky State Plumbing Code requires that runoff water from downspouts and sump pumps be directed to storm sewers or drainage ditches, not sanitary sewer lines. When a sewer line is overloaded with this "clear water” from heavy rains, water can backflow through the sewer lines into basements where there are fixtures or floor drains.

If your basement has downspouts or sump pumps connected to the sanitary sewer system, you could be at risk for a basement flooding situation. Also, if your neighbors have these "improper connections,” you could be at risk.  

Fortunately, MSD offers a no-cost program to fix your improper connections and bring your home up to code. The program is convenient and available to almost anyone with a basement in the Metropolitan Sewer District. The work is performed by an approved Louisville plumbing contractor such as Dauenhauer.

We have a dedicated work force at Dauenhauer just for MSD Program projects, so we can schedule these projects with no wait for the customer. When we take on an MSD Plumbing Modifications program project, we send out Ted or Joey for an assessment, followed up by Ben, Eddie or Frank who complete the work.  Our efficient process and dedicated workforce means the project is typically complete in 1-2 days (our competitors can take 2-3 days).  

If you think your basement could be at risk for flooding, call Dauenhauer at any hour. We’ll be right out, rain or shine, to see how we can help.
