gas hot water heater ripoff??

[Marci Stein]

my tenant told me gas hot water heater is leaking big time - plumber replaced it with a new gas hot water hearter . over the phone quote was$ 450..

bill came today for $695,with labor. i thought initial quote was for everthing. how much have you paid for a gas hot water heater , with labor?

i am tempted to have him take it back and not pay?

am i getting ripped off??
