Is there a real difference in water and electricity consumption? Personally, I don’t use a lot of water to wash my dishes (by hand), but maybe I should install a flow meter to make sure.
What is your opinion on the subject? Do you have any evidence or studies available that could confirm your intuition? Or do you have other alternatives in mind?
That’s how it is in the US. Sometimes you may have to disconnect and connect things underneath with limited clearance, and usually have to disconnect the drain tube on the sink side. It may be screwed into the countertop. There are leveling feet to adjust. It also may or may not be hard wired. It just takes a few minutes in theory, but tight clearances can make it a pain.
