My 3 year old Whirlpool 40 gallon water heater decided to stop working yesterday morning (my original water heater lasted 24 years) - the piezoelectric system does not have a visible spark and the gas control valve/thermostat unit to re-light the pilot light will not work either. Since its under a 6 year warranty, Whirlpool will send me one free part. The control unit is $220 and the piezoelectric system is $91, so I opted for the control unit for free. I need a recommendation for someone reasonable to install the new water heater control valve, so I can go back to hot showers
