I hope there is someone here who can help.
We had a dishwasher installed before Christmas. The contractor took off the washing machine fitting to the tap and replaced it with a "y" connector, adding one route back to the washing machine and the other route to the dishwasher, iyswim.
A month or so later and our laminate wood flooring has started to bubble. The laminate was laid new just before we moved in 2.5 years ago (we wouldn't have chosen wood laminate for a kitchen but that's by the by). DH pulled both appliances out, it was obvious that the "y" connector hadn't been fitted properly (because there was a pipe running underneath so it was at an angle) so every time either appliance was used it was spraying water out - but of course being at the back we didn't notice until it had soaked through the flooring into the main part of the room.
The contractor came round to make good, but DH had already done it. He admitted it was probably his fault and accepted how it had happened, but has also said "it's one of those things".
My question is - who is responsible for paying for the new flooring? The contractor has said he will do the work but is reluctant to pay for the replacement. My view is that we wouldn't have been replacing it had it not been damaged by the leak caused by the work that he did. I guess this is an AIBU to expect him to pay?
Thanks for reading, and would appreciate your views.
