Tap water pH is adjusted by local water treatment centers to ensure that minerals present in natural water sources do not deposit in pipes and water meters thereby causing corrosion. Calcium compounds for instance that are are present in most lakes and streams will precipitate out if water becomes acidic, that is the pH drops below 7.0. To prevent this damage from occurring, water treatment centers add base chemicals to the water supply to make it more alkaline. Thus in most regions on the country tap water is alkaline with a pH of about 8.1.

Most tap water is not completely pure water, but if we consider it as pure, it would be classed as pH 7 - completely neutral.

Drinking water, and water in the body is pure therefore pH 7, but just tap water water could have a pH from 6.5-8.5.

Decent water companies should produce tap water from pH 7-8, but it is never safe to assume tap water as neutral.

Depending on where you live, your tap water is pH7 +/-1. The hot water will be less acidic than the cold water because carbon dioxide is less soluble in hot water. Most municipal water is pH balanced higher than 7 so that it does not dissolve lime scale and expose lead salts in Plumbing.
