Expansion Tank Needs
Closed plumbing systems require an expansion tank to prevent pressure buildup, adding to the installation cost and complexity.
Permit Delays
Costa Mesa requires a permit for water heater replacement; inspections can delay the project if not scheduled properly.
What to Expect During Installation
A licensed plumber will first obtain the required permit and inspect your current setup for code compliance. The old unit is disconnected and removed, then the new water heater is installed with seismic straps and an expansion tank if needed. After installation, the system is tested and the inspector signs off.
