Tips for Indianapolis Homeowners

Winterize your system. Indianapolis winters can be harsh. Ensure pump chambers, risers, and exposed pipes are insulated before the first freeze.

Maintain your mound system. Many properties in low-lying areas near Indianapolis use mound systems. Keep the mound clear of trees and shrubs, which can damage the distribution pipes.

Know your county rules. Hamilton and Johnson Counties have specific requirements beyond state minimums. Always check with your county health department before scheduling repairs.
