Current code changes have been made to all water heaters installed in San Antonio.
* All water heaters installed within San Antonio city limits must have a vacuum breaker installed on the cold side inlet.
*A sediment trap has to be installed before the gas control valve to prevent debris from the gas line entering the control valve or pilot assembly.
IMPORTANT NOTE: All water heaters have a T&P (temperature and pressure relief valve) and a T&P drain line. This line must have continuous fall and be piped to the outside of the home. This valve and line is the safety mechanism for your water heater and releases pressure if excess pressure is reached within the tank.
