Common Questions
Questions homeowners ask about plumbing.
Note: dollar figures below are national averages from our v3 cost index (Craftsman labor hours x BLS regional wages + PPI-adjusted materials + verified permit fees + NAHB overhead).

For metro-specific numbers, see the cost-index pages.

Tankless vs tank water heater?+
