It's important to understand that the water from your
bathroom tap may not be suitable for drinking due to a few factors. Firstly,
the water from your bathroom tap may contain higher levels of minerals, such as
calcium and magnesium, which can make the water taste different and may not be
suitable for drinking.
Secondly, the water from your bathroom tap may not be
treated to the same level as the water from your kitchen tap, which means it
may contain harmful bacteria or other contaminants. However, in countries like
the USA and the UK, there is a reliable purifying system in place that ensures
clean water is available in every part of the city. The water from your kitchen
tap is treated to a high standard, which means it's safe to drink.
The same clean water that goes to the kitchen also goes to
the bathroom, and it's available in every street, restaurant, and hotel. So,
you can rest assured that the water from your kitchen tap is safe to drink, and
you should avoid drinking the water from your bathroom tap.
This is not the case with African countries. Here most water
is been stored in a tank and further distributed to the house. Although some
houses have vitrified clay (VC) pipes underground that carry water to the house
in a more purified form. Often, what is used to carry water in most houses is
copper or lead pipe. When water sits on this pipe for so long it becomes warm
which then generates some toxic metal that contaminates the water. If you run
your tap frequently you’ll often notice some cold water rushing out. That cold
water means that you have flushed out any water that has been sitting in the
metal pipes that run through the house.
The kitchen sink is usually applied with a filter that
filters the water coming from this pipe making it safe for drinking. Except
you’re familiar with your house pipe connection that carries water it is not
advisable to drink water from your bathroom tap.
In summary, factors such as unclean storage tanks, lead
pipes generating toxic metals and filters not applying to the bathroom tap. It
is not advisable to drink tap water.
