Waco sits on the famous Texas Blackland Prairie with heavy, expansive clay soil that swells when wet and shrinks when dry, creating relentless pressure on rigid cast iron pipes. Combined with Waco's mature oak and pecan trees that seek water in sewer lines, cast iron pipes often deteriorate rapidly. If your Waco home was built before 1975, especially near Baylor University or in historic neighborhoods, schedule an inspection immediately.
Waco homes built before 1975 near Baylor University, Downtown Waco, North Waco, Castle Heights, and Dean Highland often have cast iron pipes that are 50+ years old—well past their expected lifespan. Watch for these warning signs:
Multiple drains backing up simultaneously indicates widespread pipe damage
Sulfur or rotten egg smells signal cracks in your cast iron sewer line
All drains affected (not just one) points to main line issues
Unexplained soggy areas near your sewer line path
Waco clay soil + leaking pipes = serious foundation problems
Oak and pecan trees seek water in aging cast iron pipes
If you notice these signs, schedule a cast iron pipe camera inspection immediately.
