The 10 Common Types of Water Filtration System at Home

27/1/2021, · The Ideal pH level of tap water is 7.5. The pH level between 7.0 and 8.0 is preferable because if the tap water pH level is below 7.0, ,the acidity, may cause corrosion to pipes, appliances, and fixtures. If the pH level is above 8.0, the alkalinity may produce minerals deposits inside the pipes and on floors.
