D. An excess of active hydrogen in the tank. This is caused by corrosion protective action of the anode.
Smelly water may be eliminated or reduced by chlorinating the water heater tank and all hot water lines. Contact the local Sears Service Center concerning this Chlorination Treatment. Chlorination of the tank is not covered by the water heater’s warranty.
If smelly water persists after this chlorination treatment, it may be necessary to chlorinate or aerate your water supply to eliminate the problem.
Do not remove the anode leaving the tank unprotected. By doing so, all warranty on the water heater tank is voided.
“AIR” IN HOT WATER FAUCETS
HYDROGEN GAS: Hydrogen gas can be produced in a hot water system that has not been used for a long period of time (generally two weeks or more). Hydrogen gas is extremely flammable and explosive. To prevent the possibility of injury under these conditions, we recommend the hot water faucet be opened for several minutes at the kitchen sink before any electrical appliances which are connected to the hot water system are used (such as a dishwasher or washing machine). If hydrogen gas is present, there will probably be an unusual sound similar to air escaping through the pipe as the hot water faucet is opened. There must be no smoking or open flame near the faucet at the time it is open.
RUMBLING NOISE
