Does the water in loft tank reach drinking taps or is it only for heating?

In most residential plumbing systems, the water stored in a loft tank (also known as a cold water storage tank) is not directly used for drinking. The primary function of a loft tank is to provide a constant supply of cold water to the taps and fixtures in the house. The water stored in the loft tank is typically fed from the mains water supply and is not treated to make it drinkable.

Drinking water in most homes comes from a separate water source that has been treated to meet drinking water quality standards. This water is typically stored in a storage tank or cistern located underground or in a purpose-built structure. From there, the drinking water is distributed throughout the house through a separate set of pipes, ensuring that it remains clean and safe for consumption.

The water in the loft tank, on the other hand, is mainly used for non-potable purposes, such as washing, bathing, flushing toilets, and running appliances that require a cold water supply. To ensure that the water in the loft tank is suitable for these purposes, it may be treated with chemicals to prevent bacterial growth and corrosion.

It is important to note that the water in a loft tank should never be consumed unless it has been specifically treated and tested to meet drinking water standards. Drinking untreated water from a loft tank could pose a health risk, as it may contain harmful bacteria or contaminants.

If you are unsure about the quality of water coming from your taps, it is advisable to consult with a qualified plumber or water quality expert to ensure that the water is safe for consumption. They can assess your water supply and recommend any necessary treatment or maintenance to ensure that you have access to clean and safe drinking water.
