The kitchen in a home has a complex set of plumbing pipes and various fixtures. Any kitchen plumbing concern needs to be addressed by licensed plumbers with the best tools.
Now, imagine a commercial kitchen. Unlike a residential kitchen, a commercial kitchen must work for hours at a time, often from early morning until late in the evening. And it needs to service an enormous number of people with a variety of different types of food that must be grilled, baked, fried, deep fried, or cooked with special equipment like a pizza oven. On top of all that food preparation, the kitchen must handle immense disposal of food waste.
