It’s tricky because to be successful in claiming legal liability you generally need to establish negligence.
Burst common property pipes are usually an event that is not due to OC/BC negligence. And if that’s the case, your chances of wining a claim against the OC/BC on liability grounds will be small.
You can certainly try claiming on the OC/BC’s insurance. But OC/BC insurance policies usually specifically exclude lot contents except for lot fixtures and fittings. Lot carpets and floating floors are usually specifically excluded.
So you’d have to try a claim under the OC/BC’s legal liability cover.
Sometimes it works.
