A rotten egg smell in your hot water can be caused by various factors. If you can only smell this smell on your kitchen faucet, it could be due to the fact that the drain is partially blocked by decomposing remains. The odour can also come from your water purifier if it is not regularly maintained. In most cases, a sulphur odour is caused by water with a high magnesium content that comes into contact with the original magnesium anode. The Corro-Protec anode is the ideal solution to this problem, because in addition to eliminating odours in a few hours, the anode stops the corrosion of your water heater and is guaranteed for 20 years.
