Gas-fired water heaters require a mechanical permit and electrical water heaters need a plumbing permit to ensure that the unit is installed properly with a temperature and pressure relief valve, the valve has an attached drainpipe, and the entire system is installed in a safe location.
If a permit is issued, you will need to do the following: Comply with the provisions of the permit. (This includes any monitoring and reporting requirements.) Notify TCEQ if you wish to discontinue permit coverage. Pay an Annual Water Quality Fee. As long as the permit is active on September 1st of the year, you will receive an invoice for this fee.
