When we moved in to this house it had a water softener. It uses blocks of salt. It’s quite nice having less limescale and I imagine it’s been very good for the boiler dishwasher and washing machine. However, it’s gone on the blink. Kaput. It is very expensive to repair. Around £500! I could cover this with savings but I’m not sure it’s worth it or I wondered if maybe wise mumsnetters have an alternative idea?
