What is the average cost to replace a water heater?
A standard tank water heater replacement costs $800–$1,800 installed. Tankless water heaters cost $2,500–$5,000 installed but offer significant long-term energy savings.
How do I know if my pipes need to be replaced?
Signs include discolored water, low pressure, frequent leaks, or pipes made of galvanized steel or polybutylene (common in homes built before 1995). A licensed plumber can inspect and camera your lines.
Do plumbing repairs require permits?
Major plumbing work — new lines, water heater replacement, sewer work — typically requires permits. Simple repairs like fixing a leaky faucet usually do not. Always ask your plumber upfront.
