I have just completed a new Masterton build and reported the 180 day maintenance issues. One issue is that the Look Blikk sink mixer taps installed in the kitchen and laundry have been troublesome - they flop around on the stalk and won't stay in one position. Every tradesman who has seen them has said they are not great and require a hole to be cut in the under sink cupboard which might solve it, but many have had to be replaced.
Has anyone had experience with these units, especially with Masterton and has it been fixed or replaced?
