My OPINION is that the pump itself - the container and motor, sold as a unit - is separable from the drain piping or tubing. A condensing gas-fueled tankless water heater recaptures much of the heat that would have gone up the flue, uses it to help heat the domestic hot water, and produces a much-cooler exhaust and condensate that is typically vented through PVC piping to the exterior. Some home inspectors and HVACR technicians want the drain to be insulated either to cure an actual observed wetting problem OR because they're making their own, probably unnecessary, interpretation of one of the model energy codes.
