Hard Water

I have a tenant who has issues with hard water in his apartment – it leaves mineral residues in the sink etc., after each use, and the kettle needs frequent cleaning.

The water is perfectly safe to use. It is a central London flat, so hard water is to be expected.

We have looked at some options. Primarily installing a water softener, but this would then need the filter changed every 2/3 months.

I am not keen to have additional plumbing to maintain as I am sure it will fall to the landlord under section 11.

Where do we stand under section 11 – I am sure as long as the water is safe, we do not have to provide anything further in terms of softening.

Thanks
