Will the Gearwrench 1/2" Drive 1-1/2" 6pt. Socket 80679 work to remove an electric water heater element? Has any one used a 1-1/2" 6pt. shallow socket to remove a water heater element? Water heater elements are only on electric water heaters, not on gas water heaters. Can I use a shallow socket or do I need a deep socket?
