Damian Taylor2025-04-15Trustindex verifies that the original source of the review is Google. We have this morning just had fitted a new Rinnai 28 HWS after our 23 yr old unit " died " ( or so we thought ) Yesterday I emailed an inquiry to Rinnai and received a call back from a Kelly within hours. Kelly answered my initial queries thoroughly and quoted the replacement fitted cost including gst and then managed to book a plumber in for this morning first thing after we accepted the price and gave the go ahead. Steve the plumber arrived punctually and after checking the unit surprised us by saying it was in fact still working and a fault was in the wall mounted control unit. He was honest and said he could simply test both control units and replace any if faulty for considerably less than the cost of a brand new unit. We appreciated his candour but given the age of the old unit, decided to press ahead and change it over. Very impressed with the prompt and friendly response from Kelly and equally so with Steve's honest advice and giving us a choice of options. Well done Immerse.

I had an outstanding experience with Immerge Plumbing, and I can’t thank Kellie and the team enough for their exceptional service. After dealing with a few unreliable and unhelpful companies, I was relieved to find Immerge. From start to finish, the entire process flowed smoothly without any hassles.
