The Fur Coating Formed by Hard Water in Kettles and Pipes is Not Harmful
by Yated Ne'eman Staff

According to Yaakov Zak, the Chief Engineer responsible for water quality in the Mekorot water company, the fur coating formed by our hard water in kettles and pipes is not harmful. On the contrary, some of the salts it contains are important for our health.

In an interview published in the magazine Green-Blue, White, Zak points out that the consumer is not meant to check and supervise the quality of the water on its way from Mekorot to the outskirts of his home. This is the job of Mekorot's monitoring and inspection arrangement. On the other hand, he can play a part in maintaining the quality of the water.

Water contains salts in its natural state, including calcium carbonate. The fur coating is composed of minerals in the water and is not harmful.

The white cloud that is sometimes present in tap water dissipates quickly. It is merely air mistiness, which reaches the pipes because of swirling of the water, and is not harmful in any way.

In accordance with Regulations of the Health Ministry, Mekorot adds antiseptic material to the water, which remains effective until the water has left the faucet. A slight smell of chlorine is, therefore, reasonable, and not harmful.

A shower head should not be plunged into a bath filled with water, since the stop of the water flow and the creation of hypo-pressure may result in bath water flowing back into the clean water system. For the same reason a toilet seat should not be rinsed with a shower head or any other pipe attached to the water piping, otherwise water from the toilet may be sucked out back into the drinking water system.
