Your plumbing needs will not be the same as what your neighbour needs since all residential homes are not the same. When categorizing your plumbing needs, your contractor will include branched and series home plumbing, which is mostly responsible for bringing in water the tubs, sinks, toilets, showers and so on. To easily assess which one you have, your plumber will test this, to determine what you have.
This type of plumbing have a variety of designs, however, they all share similarities with the pipes splitting and going in different directions as they give out hot and cold water. Branched plumbing is when one floor needs cold water and the other needs hot water at the same time, and the water will split off in different directions to accommodate the needs of the users. This kind of plumbing is mostly efficient in providing hot and cold fixtures but is mostly complicated for plumbers to repair.
This type of plumbing is mostly simple as the hot water will just come from a hot water heater and the cold water will be supplied from a ground supply. They can run alongside but they are mostly separate. Since this system is just simple, plumbers also find fixing this fixture much easier as they just need to eliminate the pipes that are fine.
