I wanted to take this opportunity to commend the outstanding professionalism of the plumber who actioned this particular job. His expertise in identifying the problem and resolving it quickly and effectively was impressive. I have had previous plumbers attend to this particular issue, and also other issues, however none have conducted themselves with such a high level of professionalism. I would appreciate your conveying my personal thanks to the plumber involved and can assure you I will be utilising his services again, via Tunnel Vision WA, if and should the need arise. Many thanks again.
