Old Home Plumbing
Homes built in the 1970s may have outdated connections or insufficient gas lines, requiring upgrades during installation.
Permit Requirements
Only Oklahoma-licensed plumbers can pull permits, so unlicensed work can lead to fines or failed inspections.
Expansion Tank Needs
Closed water systems, common in newer homes, require an expansion tank to prevent pressure damage.
What to Expect During Installation
A licensed plumber will first assess your existing setup, including gas lines and venting. After obtaining the required permit, they'll disconnect the old unit and install the new one, ensuring code compliance. The job typically takes 2–4 hours for a standard tank replacement. For tankless units, additional time may be needed for gas line upgrades. Final inspection by the city may be required.
