The white crust on shower heads across Castle Hills, Texas is the visible half of a hard water problem. The expensive half is cast-iron drain lines corroding through after decades in the ground — appliances failing years before they should.
Castle Hills, Texas deals with cast-iron drain lines corroding through after decades in the ground because of hard SAWS water. Softening is not a luxury upgrade here; it is the difference between replacing a water heater on schedule and replacing it early.
