There would not be "technical information" about this situation any way. What would it say? Something like, "After the sink is installed always keep a pan under the sink to catch any "overflow water", or if the sink is installed on top of a countertop, be sure to seal around the drain hole and around the sink so any water exiting the overflow opening is trapped under the sink"? This "situation" needs a phone call to the company's customer service department.
By tech. info, I was looking for dimension specs, install instructions....NOTHING there
