What to expect during installation
A licensed plumber will first pull a permit with the city. The job typically takes 3–6 hours for a tank replacement, longer for tankless. They'll disconnect the old unit, install the new one with required safety devices (expansion tank, T&P valve), and test for leaks. After final inspection, the permit is closed.
