Completed Operations Claim Due to Installation of Refrigerator

Our insured was hired by the claimant to install a mini-refrigerator and freezer unit; this involved running the water line for the ice maker to the cold water supply for the claimant in her house. The units were purchased by the claimant and the insured was hired only to install them.

During the installation, the water line became crimped and now, several months later, a leak where the water line was crimped caused water damage to the house. Apparently, the freezer unit was sitting on the water line when the insured installed the line causing the crimp, but at the time of the installation, the insured was not aware of this. Would the general liability policy of the insured apply to the water damage claim?
