Just wanted to email to say how fantastic your sales team are, without doubt the most pleasant company I’ve dealt with in the 5 years I’ve been here, and just thought it needed relaying back.

Robbie | PTS Plumbing

Thanks for your response as a result of your first email Boys and Boden Welshpool now have CalChem on the shelf. Many thanks for the technical advice.

Ged | Calmag Customer

Thank you for your guidance concerning our high salt consumption...

Thank you for your advice concerning our high salt consumption in our softener. Your suggestion of a leak in the seal under the black cap with 2 screws was correct.
