Smelly water means dacaying organic material. Question is: is the material in the water heater, water tank, in the lines or all of the above. Flush all hot and cold water lines by first draining water tank, add a potent amount of lemon scented Clorox to a tank refill. Fire up the old water heater. Purge the water tank by progressively using all the faucets aboard starting with the closest and ending with the farthest away from the supply... at least 3 times using the lemon scented Clorox mixture. This may tax the water pump, so you may want to have a new or spare one ready to swap out. Flush tank 2xs at least.
Taste test water tank at the tank.... If foul taste still there, flush again or there is a trick, but it must be done right: With the vessel water lines disconnected at the tank- plug tank outlets. Fill tank 3/4 full and Mix in a 2% mixture of sulpheric acid into the tank and agitate 5 minutes only . Drain/flush 2xs with fresh water only- no clorox! A 2 % acid mixture will dilude into a drain and will not cause a pollution issue- use no more that this percentage. Taste test. If good taste, hook up water lines and without heating up the water heater. Taste test at progresively outbound faucets. If taste is present at closest faucet to water heater, replace hot water heater. Charge up system again with water heater on. Taste test again.
This is a process of elimination. Using logic as above should solve the problem. First consider environmental conditions and how much the heater is left on. Factor this consideration first so the problem does not reappear later.
