Slighly acidic water is fine to drink and wash with, but it can degenerate your water heater over time. Some water heaters have an in-built anode rod of soft metal that will break down instead of the other components of the water heater.anodes should be replced when they have degraded more than 75%, usually yearly, but this is dependent on the quality of water used.
