Your plumber, Clive Adams, carried out work on the above appliance on Thursday 18th November last. I was very satisfied by his tidy workmanship, and his attitude to the work. While he was working, he suspected that the existing house plumbing near the location of the softener was unsatisfactory; his suggestion as to an easy remedy; and readiness to carry it out. This was completely in contrast to the performance of domestic plumbers in my previous experience. As ‘senior citizens’ we do not usually find many of the building trades so considerate. I should be grateful if you would place my comments in your staff records.
