Is it better to run water pipes on the ground or on the top?

From a construction perspective, it is generally not recommended to go to the top! Because that will greatly increase the difficulty of construction and the budget. The cost of roofing will probably exceed the budget of ground walking by 20 to 40 yuan. But from the perspective of future use, walking on the roof is safer and more worry-free than walking on the ground. Because the water pipes laid from the ground (picture below), even if they have passed the pressure test, there is no guarantee that they will not leak one day in the future. Water is a substance that flows downward. It will slowly penetrate the floor and invade the ceiling of the neighbor downstairs, slowly causing damage. And if the ground in your home is paved with tiles or floors, you won't notice it at all. By the time the people downstairs came to the door, the damage would have already been considerable. The next step is to pry the floor tiles (floor) to find the leaking point, reconnect the water pipes, restore them, and repair the damage caused to the people downstairs. The people downstairs may even file a claim. Although the probability of such an accident happening is extremely low, no one can bear it. Not only is it a waste of time and money, but it also takes a toll on one's vitality.
