Client has us out today because she is wanting her electric water heaters serviced as she hasn’t performed any maintenance and has lived here for 6 years. One unit is located in the basement, piping ram to this unit is cpvc, the expansion tank is unsupported and held up by cpvc. The other unit is located around the back side of the basement in a utility storage type room accessed through an exterior wall. This water heater is older and does not have an expansion tank and is also piped in with cpvc. Today we went with just flushing both units, sending other options to email on file.
