Major Septic Problems That Can Affect Your Home
Backyard Flooding
Water and waste backing up from your septic system can flood your yard. Flooding can ruin your lawn and make outdoor activities unpleasant.
Bad Odors in Your Home
Sewage smells from your drains or yard are more than unpleasant—they signal your system isn’t working right. Bad odors inside can make your home feel unclean and unsafe.
Drains That Don’t Work Properly
When water drains slowly, your septic system might need attention. Slow drains can turn into serious backups if not fixed.
Â
Raw Sewage in Your Home
A backup of sewage in your home is a major health hazard. This creates a health hazard and can damage floors, walls, and furniture.
Unexpected Septic Emergencies
Septic issues that are left alone can lead to big, unexpected bills. Addressing problems early helps avoid high repair costs.
Septic Leaks Can Hurt Your Home
A failing septic system can leak harmful bacteria into your soil and water. This puts your family, pets, and landscaping at risk, and can hurt your property’s value.
