Who is liable for leak

[Help me]

Weve had two radiators replaced and a couple of weeks later (once the heating had gone on )one of them leaked ruining the wood laminate flooring. The plumber came and repaired the leak and said the problem was the original type of joint that was there was not suitable and should never have been fitted.
These pipes were there before we moved in and haven’t leaked for the 15 years we’ve been here.
It’s only since the radiators were replaced.

If we go through our house insurance for the flooring there is a big excess to pay and obviously our premiums will go up next year. Is this something we just have to accept or should the plumbers insurance cover it?

What was the joint do you have a picture?

Nearly all the plumbers and heating engineers I know have disclaimers in their estimates or quotes stating that they cannot be held responsible for any unforeseen damages arising from the work to be carried out on existing supplies , and shall only be responsible for the work they have installed it is not unusual to have a few issues when connecting to existing supplies but the sign of a good trades person is how he or she tackles the problems and minimises any incovience and damage .

Was/is this joint visible to the plumber or was it hidden under the floor?

If it was visible and they thought it ‘was not suitable and should never have been fitted’ - then they should have brought it to your attention at the time and replaced it then, at an additional cost to you.

If it was hidden then they can’t reasonably be held responsible for it.

Pictures of before and after and we’ll be able to give you a better answer.
