About this detail

An electric water heater is mounted on a structural angle iron platform and support provided by the plumbing contractor. The tank features typical heat traps, ball valves, and dielectric unions on both domestic cold water supply and domestic hot water lines. A Watts LF288A lead-free anti-siphon vacuum breaker is installed on the cold water inlet. An Amtrol model ST-5-C expansion tank with a 3.4 gallon maximum expanded volume connects to the domestic cold water line along with a check valve. A temperature and pressure relief valve is piped full size down to a drip pan, which drains through a 1 inch line connected to the tailpiece of a sink. All piping is insulated per project specifications.
