Tenant reported water leak under the kitchen sink to the landlord and turned off the valve under the kitchen sink per landlord's instruction. The plumber fixed the leak 3 days later. Landlord discovered severe water damage 3 weeks later during the inspection to the property. As stated by the plumber, the wood floor and based board under the kitchen sink have already warped and bulking when he went there to fix the leak. Tenant did not want to provide any details about the incident but just wanted to have their security deposit back. Can the tenant be hold responsible for the damages due to their negligence: 1. didn't report the water leak when it first arose; 2. never reported water damage until landlord discovered it; 3. did not take any reasonable care (mop off the leaked water etc).
