I emailed this all and photos to the SS. He got back to me pretty quickly and said he would look into next week.
As those reading my blog know I am obsessed with driving past, so on a drive by after sending my email I chanced upon the plumbers back on site - bingo. We had a quick chat about the problems. He showed me the plans he has and yes, he was working off the original draft construction plans, not the ones that we actually agreed on and signed. So as people have mentioned before, often they find errors because the contractors are given the wrong plans. Just annoying that draft plans are sent out. I was very adamant that I wasn't signing any Construction Plans until everything was spot on (to the best of my knowledge). I felt very apologetic, but the plumber was just disappointed that he finds this out from me and that he didn't have the right plans. So I headed home, printed off the right plans and took them around to him (perhaps with a 6 pack beer - bribery!) to thank him for making it right. He thanked me for bringing the new plans as he called the office (guessing plumbing office) and they had no record of any newer plans - ie my signed plans!!! Anyway, we will head over this morning and see what is happening.
Edit - 11 Jun
Went by on the weekend to do a double check and the washing machine taps now fixed.
Also checked the shower rose height to see if fixed - well a shower rose was adjusted higher, just the wrong bathroom!!! Not too fussed as I actually wanted all the shower roses at 1900mm, so now I might just say, leave our ensuite at that height and correct the bathroom one as per the plans and discussed on Friday!
